YY/CY/SY LSZH Flexible Control Cable 300/500V
Halogen-free, low-smoke flexible control cable for tunnels, public buildings and confined spaces — unscreened, copper-braid screened or steel-braid armoured, 0.5 to 2.5 mm², up to 50 cores.
On the designation: the Y, CY and SY codes are inherited from the PVC control-cable family this construction is sold alongside. On this cable the insulation and the sheath are halogen-free (TI6 / TM7), so the code is a market convention rather than a description of the compound — the halogen-free equivalents are normally designated in the H nomenclature, such as LiHCH or the H05ZZ-F family.

Product Overview
For the places where PVC smoke is the real hazard
A halogen-free, low-smoke control cable exists for one reason: in a fire, ordinary PVC releases hydrogen chloride, which is corrosive to electronics and acutely hazardous in a confined space, and it produces dense smoke that hides the exit. Where the cable runs through a tunnel, a metro station, a hospital, an airport concourse, a data hall or any space people have to evacuate, that is a specification decision rather than a preference. This is the halogen-free version of our flexible control cable family, in the same three construction levels: unscreened, copper-braid screened and steel-braid armoured.
One naming point has to be dealt with, because it is a genuine contradiction rather than a matter of taste. In this product family the letter Y means PVC — YY is PVC insulated and PVC sheathed, CY and SY are the screened and steel-braided versions of the same thing. So “YY/CY/SY LSZH” reads literally as “halogen-free PVC cable”, which cannot exist. The YY/CY/SY part is the market designation this product is sold under and the structure it shares with the PVC versions; the compound system is entirely different, and it is the compound that makes the cable halogen-free. Halogen-free control cable is normally designated in the H nomenclature (LiHCH, H05ZZ-F family) precisely to avoid this confusion, and we describe the construction in full in Table 2 so the actual materials are unambiguous.
On the fire performance, three standards are involved and they are not interchangeable. IEC 60754-1 / EN 60754-1 measures the quantity of halogen acid gas released when the compound burns — that is what “halogen-free” means, and it says nothing about smoke. IEC 61034-1/-2 / EN 61034-1/-2 is the smoke density test, which is what “low smoke” means. IEC 60754-2 / EN 60754-2 covers the acidity and conductivity of the combustion gases, which is the corrosion question. Datasheets that cite only 60754-1 and then claim “low smoke” have not tested the second property at all.
The temperature rating follows from the compound. The TI6 halogen-free thermoplastic insulation (EN 50363-5 family) and the TM7 halogen-free thermoplastic sheath (EN 50363-7 family) are rated at +70 °C long-term conductor temperature. The +85 °C figure that appears on some datasheets for this product class has no compound behind it; if the application genuinely needs more than 70 °C, the answer is a cross-linked halogen-free compound and it has to be quoted against its own data sheet rather than assumed.
The construction otherwise follows the family: Class 5 flexible stranded copper to IEC 60228, cross-sections from 0.5 to 2.5 mm², up to 50 cores at 0.5 mm², a 2000 V AC conductor-to-conductor and 1200 V AC conductor-to-screen test, and flame retardance to IEC 60332-1-2. For the PVC versions of the same family see the YY/SY/CY Control Cable and the CY Shielded Control Cable.

Key Features
Eight things that matter on a halogen-free installation
Halogen-Free Compound
No halogen acid gas on combustion, tested to IEC 60754-1 / EN 60754-1 — the property that protects both people and the electronics in the same room.
Low Smoke Density
Tested separately to IEC 61034-1/-2 / EN 61034-1/-2, because a halogen-free cable is not automatically a low-smoke one and the two claims are not interchangeable.
Acid Gas Emission Tested
IEC 60754-2 / EN 60754-2 covers the acidity and conductivity of the combustion gases — the corrosion question that matters most in a control room.
TI6 / TM7 Compound Family
Halogen-free thermoplastic insulation to the EN 50363-5 family and sheath to the EN 50363-7 family, rated +70 °C long-term conductor temperature.
Three Construction Levels
Unscreened, tinned copper braid screen for EMC, or galvanised steel braid for mechanical protection — the same choice as the PVC family.
Class 5 Flexible Copper
Stranded copper to IEC 60228 / DIN VDE 0295 class 5, which keeps a 25- or 50-core halogen-free cable workable in a cabinet.
Up to 50 Cores
50 cores at 0.5 mm², 24 at 0.75 mm² and typically up to 6 at 1.0–2.5 mm², with the availability matrix published.
Flame Retardant
Single-core vertical flame propagation to IEC 60332-1-2 / EN 60332-1-2 on the finished cable, in addition to the halogen and smoke tests.
Applications
Where a halogen-free control cable is specified
Confined spaces, evacuation routes and anywhere the corrosion of electronics after a fire is part of the risk assessment.
01
Tunnels and Metro Systems
Road and rail tunnels, where the cable run is long, escape is difficult and smoke density is the controlling hazard.
02
Hospitals and Healthcare
Wards, theatres and plant rooms where patients may be non-ambulatory and corrosive combustion products would take equipment out of service.
03
Airports and Transport Terminals
Concourse and baggage-handling areas with high occupancy and large volumes of exposed cable in ceiling voids.
04
Data Centres and Control Rooms
Where the post-fire corrosion of electronics is the dominant loss, and acid gas emission matters as much as flame spread.
05
Public Buildings and Auditoria
Schools, stadia, shopping centres and theatres, where reaction-to-fire performance forms part of the building approval.
06
Rail Rolling Stock and Depots
Rolling-stock wiring and depot installations where halogen-free cable is the standing requirement.
07
Underground and Confined Plant
Basements, pits, cable ducts and ships’ spaces where smoke has nowhere to go.
08
Battery and Energy Storage Rooms
Enclosures housing lithium cells, where both fire load and gas corrosivity are part of the design case.

Table 1 Three halogen-free construction levels
| Variant | Construction | Braid or screen | What it is for |
|---|---|---|---|
| Unscreened | Halogen-free insulation, laid-up cores, halogen-free sheath, no braid | — | General halogen-free control wiring in ducts, voids and trays where no screen or armour is needed |
| Copper braid screen | Halogen-free insulation, tinned copper wire braid over the laid-up cores, halogen-free sheath | Tinned copper wire braid, optical coverage approx. 85% | Halogen-free installations that also need EMC screening for drives, encoders and signal circuits |
| Steel braid armour | Halogen-free insulation, galvanised steel wire braid, halogen-free sheath | Galvanised steel wire braid | Halogen-free installations where the cable is pulled, dragged or exposed to mechanical damage |
The variant names in the product title are the market designation this cable is sold under. Note that Y means PVC in this family, so the YY/CY/SY label describes the construction level rather than the compound — the halogen-free compounds are named separately in Table 3. The steel-braided variant has no CENELEC harmonised part standard, and in common with the PVC family its braid is armour rather than an EMC screen.
Table 2 Core count available at each cross-section
| Cross-section | Core counts normally offered | Typical maximum |
|---|---|---|
| 0.14 mm² | 2, 3, 4, 5, 10, 12, 18, 25, 32, 50 | 50 cores |
| 0.25 mm² | 2, 3, 4, 5, 7, 10, 12, 18, 25, 32, 50 | 50 cores |
| 0.38 mm² | 2, 3, 4, 5, 7, 12, 18, 25, 32 | 32 cores |
| 0.5 mm² | 2, 3, 4, 5, 7, 12, 18, 25, 32, 50 | 50 cores |
| 0.75 mm² | 2, 3, 4, 5, 7, 12, 18, 24 | 24 cores |
| 1.0 mm² | 2, 3, 4, 5, 6 | 6 cores |
| 1.5 mm² | 2, 3, 4, 5, 6 | 6 cores |
| 2.5 mm² | 2, 3, 4, 5, 6 | 6 cores |
The core counts listed are the typical range offered at each cross-section, not a limit set by the conductor standard. Most panel and machine wiring uses 2–12 cores; 18–50 core constructions are common in plant wiring and are quoted individually. The 0.75 mm² row is highlighted because it is the size most often held in stock.

Halogen content, smoke density and acid gas emission are three separate properties tested to three separate standards, and this table names each against its own standard rather than collapsing them into one “LSZH” claim. The +70 °C conductor temperature is the long-term rating of the TI6 insulation and TM7 sheath compound family; a higher temperature would require a cross-linked halogen-free compound quoted against its own data sheet, and we do not publish 85 °C. The family has no CENELEC harmonised part standard, so the remaining standard-based values are the conductor class (IEC 60228) and the flame test (IEC 60332-1-2), with the compound families named in the EN 50363 series. Confirm the requirement against the fire strategy for the specific project.
Certificates & Standards
Verify before you buy — we make it easy
Halogen-free to IEC 60754-1
The compound releases no halogen acid gas on combustion, tested to IEC 60754-1 / EN 60754-1 (DIN VDE 0482-754-1) — the property that protects people and electronics in a confined space.
Request test report →Low smoke to IEC 61034-1/-2
Smoke density is tested to IEC 61034-1/-2 / EN 61034-1/-2, separately from the halogen test. A halogen-free cable is not automatically a low-smoke one, and we quote the second test rather than implying it.
Request test report →RoHS and CPR documentation
RoHS 2011/65/EU compliance declaration, and a Declaration of Performance under CPR (EU) 305/2011 for the construction supplied — for a halogen-free thermoplastic control cable of this type the realistic Euroclass is Eca, and a higher class such as Dca or Cca is a different compound and a different test programme. We do not use the phrase “CE certified”: there is no CE certification for cable, only a manufacturer’s declaration, and a DoC is provided on request where it applies.

Transparency note: certification status and exact scope should always be confirmed against the certificate for the selected product configuration. We provide the certificate and test reports with every quotation — no blank promises.
Quality & Factory
Fire performance tested separately from the electrical release test
On a halogen-free cable the compound is the product, so the records that matter include the material data sheet as well as the routine electrical tests.
- 1Compound verification — the halogen-free insulation and sheath compounds are checked against the compound data sheet and the TI6 / TM7 designation before extrusion.
- 2In-line process monitoring — conductor diameter, insulation and sheath thickness and the lay length of the core bundle are tracked during production.
- 3Electrical routine tests — conductor resistance, insulation resistance and the withstand voltage test between conductors, and between conductor and screen where fitted, are measured on the finished cable and recorded.
- 4Material documentation — the compound data sheet covering the halogen content, smoke density and acid gas test results is supplied with the quotation so the fire performance can be filed with the project documentation.

FAQ
Questions buyers ask before ordering
LSZH stands for low smoke zero halogen. The two halves are separate properties with separate tests: zero halogen is IEC 60754-1, which measures the halogen acid gas released on combustion, and low smoke is IEC 61034-1/-2, which measures smoke density. A cable can be halogen-free and still produce a lot of smoke, so citing 60754-1 alone and claiming “low smoke” is not a test result. We quote both, plus IEC 60754-2 for the acidity of the gases.
Because it is the market designation this cable is sold under, and it is a real contradiction — YY means PVC insulated and PVC sheathed and CY and SY are the screened and steel-braided versions, so a literal reading is “halogen-free PVC cable”, which is impossible. What is actually shared with the PVC family is the construction geometry; the compound system is entirely different, and it is the compound that makes the cable halogen-free. Halogen-free versions of this product type are normally designated in the H nomenclature such as LiHCH or the H05ZZ-F family, and we name the actual compounds (TI6 insulation, TM7 sheath) in the specification table so nothing rests on the label.
+70 °C long-term. That is the rating of the TI6 halogen-free thermoplastic insulation (EN 50363-5 family) and the TM7 halogen-free sheath (EN 50363-7 family). The +85 °C figure that circulates for this product class has no compound behind it, so we do not publish it. If the application genuinely needs more than 70 °C, the answer is a cross-linked halogen-free compound, and we will quote it against its own data sheet rather than assume it.
Yes — screened halogen-free control cable is a normal choice for control and feedback wiring near a drive, and the screen is terminated at the gland in the usual way. It is not the right cable for the motor output, where a symmetrical drive cable belongs. Note also that in a halogen-free installation the glands, conduit and trunking are part of the same decision; a halogen-free cable through a PVC gland is a compromise worth avoiding.
It is an indoor control cable. Halogen-free thermoplastic compounds are more moisture-sensitive than PVC in some formulations, and the sheath is not UV-stabilised for permanent outdoor exposure. Tell us the environment — UV, humidity, washdown, oil — and we will confirm which compound suits it, or quote a different family if the answer is none of them.
Yes. The compound data sheet covering the IEC 60754-1 halogen content, the IEC 61034-1/-2 smoke density and the IEC 60754-2 acid gas results is supplied with the quotation, together with the conductor resistance and withstand voltage records for the batch. Because the fire performance belongs to the compound, the data sheet is the document a fire engineer actually needs — not a certificate for the cable as a whole.
A Declaration of Performance under CPR (EU) 305/2011 can be issued for the construction supplied, and the Euroclass is stated in it — for a halogen-free thermoplastic control cable, Eca is the realistic level, and a higher class such as Dca or Cca is a different compound and a different test programme. We will not print an Euroclass we cannot support with a DoP, so ask for the declaration for the specific construction.
MOQ is 100 m with sample orders available for project qualification. Stocked configurations ship in 3–5 days, and made-to-order core counts and sections in 7–20 working days. Halogen-free compounds are held in fewer sizes than PVC, so for a large project it is worth sending the schedule early and letting us hold compound for the run.
