Product Overview
Two voltage classes under one product name
RVV is the Chinese designation for a flexible PVC insulated and PVC sheathed multi-core cable, and it is defined in GB/T 5023.5-2008 — the part of the GB/T 5023 series that covers flexible cables and cords, equivalent to IEC 60227-5. Under that standard there are two RVV types, and confusing them is the single most common error in this product category: 60227 IEC 52 is the light-duty type at 300/300 V, limited to 2–3 cores and 0.5–0.75 mm²; 60227 IEC 53 is the ordinary-duty type at 300/500 V in 0.75–2.5 mm², which is the construction this page is built around.
That distinction is not pedantry. A 2.5 mm² core cannot be a 300/300 V cable, because the light-duty type does not extend to that cross-section — so a datasheet that lists “300/300 V, 0.5–2.5 mm²” is describing two different products, and a buyer who orders to it may receive either. Table 1 sets out the two types side by side. Where a project needs 0.5 or 0.75 mm² for light duty, we supply the IEC 52 type and mark it as such; where it needs 1.0 mm² or above, or a 4- or 5-core construction, it is IEC 53 at 300/500 V.
The conductor is Class 5 flexible stranded copper to GB/T 3956, which is what makes an RVV cable easy to route and terminate by hand. Insulation is a PVC/D compound and the sheath a PVC/ST5 compound, the two grades GB/T 5023.1 assigns to flexible cables. The finished-cable withstand test follows the voltage class: 1500 V AC for 300/300 V, 2000 V AC for 300/500 V and 2500 V AC for 450/750 V, applied for 5 minutes.
Temperature-wise, the working range is −15 °C to +70 °C with a maximum conductor temperature of +70 °C. The cable is a general-purpose flexible type for indoor installation in conduits, ducts, trunking and equipment wiring. It is not an outdoor cable, not a buried cable and not a continuous-flexing cable: “flexible” describes how the cable is made and installed, not an ability to survive repeated movement.
Two compliance points are worth stating precisely. CCC certification applies to this cable type — PVC insulated cables rated 450/750 V and below to the GB/T 5023 series are in the China Compulsory Certification scope, and the certificate is provided with the shipment. CE does not apply to a cable built to a Chinese standard: where a European equivalent is needed the correct route is the EN 50525 family, and we quote it as a separate product rather than labelling a GB cable as CE. RoHS is a substance restriction and is documented by a test report rather than by a product standard; it is available on request.

Key Features
Eight things that decide the specification
GB/T 5023.5-2008
The part of the GB/T 5023 series covering flexible cables and cords, equivalent to IEC 60227-5 — the standard RVV is actually defined by.
300/500 V, 60227 IEC 53
The ordinary-duty RVV type, covering 0.75 to 2.5 mm² in 2 to 5 cores. This is the construction the page is built around.
300/300 V, 60227 IEC 52
The light-duty type for 0.5 and 0.75 mm² in 2 or 3 cores — supplied and marked separately, and never mixed with the 300/500 V sizes.
Class 5 Flexible Copper
Stranded copper to GB/T 3956 that routes and terminates by hand, which is the point of a flexible PVC cable.
PVC/D and PVC/ST5
The insulation and sheath compound grades GB/T 5023.1 assigns to flexible cables, rather than the fixed-installation grades.
Voltage-Matched Withstand Test
1500 V AC at 300/300 V and 2000 V AC at 300/500 V for 5 minutes on the finished cable, recorded against the production length.
+70 °C Conductor
A working range of −15 °C to +70 °C, with a maximum conductor temperature of +70 °C for continuous operation.
CCC Certification
CCC applies to this cable type under the PVC insulated cable scope of the China Compulsory Certification catalogue — the certificate is provided with the shipment.

Table 1 The two RVV types — 60227 IEC 52 and 60227 IEC 53
| Type | Duty | Rated voltage U0/U | Core count | Cross-sections |
|---|---|---|---|---|
| 60227 IEC 52 (RVV) | Light duty | 300/300 V | 2 to 3 cores | 0.5 – 0.75 mm² |
| 60227 IEC 53 (RVV) | Ordinary duty | 300/500 V | 2 to 5 cores | 0.75 – 2.5 mm², with 4 and 6 mm² available on some constructions |
The two types are separate products with separate voltage classes, and they must not be combined in one specification. In particular, a 0.5–2.5 mm² range cannot sit under a single 300/300 V heading: the light-duty type stops at 0.75 mm². Tell us the duty and the cross-section and we will confirm which type the order is built to, and mark the drum accordingly.
Table 2 Core count and cross-section availability
| Cross-section | Available cores | Type |
|---|---|---|
| 0.5 mm² | 2, 3 | 60227 IEC 52 — 300/300 V |
| 0.75 mm² | 2, 3 (IEC 52) or 2, 3, 4, 5 (IEC 53) | Both types are available at this size — the voltage class is confirmed on the order |
| 1.0 mm² | 2, 3, 4, 5 | 60227 IEC 53 — 300/500 V |
| 1.5 mm² | 2, 3, 4, 5 | 60227 IEC 53 — 300/500 V |
| 2.5 mm² | 2, 3, 4, 5 | 60227 IEC 53 — 300/500 V |
0.75 mm² sits on the boundary and can be supplied as either type; the 1.0 mm² row is highlighted because it is the size most often ordered in volume. Core identification follows the standard colour code for the construction, and larger or non-standard combinations are covered by the JB/T 8734 series of industry specifications where the project requires them.

| General Information | |
| Product Name | RVV Multi-Core PVC Control Cable 2–5 Cores |
| Model Designation | 60227 IEC 53 (RVV) — ordinary duty, 300/500 V, this product. 60227 IEC 52 (RVV) — light duty, 300/300 V, available separately for 0.5 and 0.75 mm². |
| Standard | GB/T 5023.5-2008, PVC insulated cables of rated voltages up to and including 450/750 V — Part 5: Flexible cables (cords), equivalent to IEC 60227-5 |
| General Requirements | GB/T 5023.1-2008 |
| Supplementary Standard | JB/T 8734.3, PVC insulated wires and flexible cords of rated voltages up to and including 450/750 V — Part 3: Flexible cords for connection. The JB/T 8734 series covers a wider size and core range than GB/T 5023 and is used as the basis for non-standard combinations. |
| Conductor Standard | GB/T 3956, Conductors of insulated cables |
| Electrical Ratings | |
| Rated Voltage (U0/U) | 300/500 V for 60227 IEC 53; 300/300 V for 60227 IEC 52 |
| Rated Voltage Test (finished cable) | 2000 V AC for 300/500 V and 1500 V AC for 300/300 V, 50 Hz, 5 minutes. 2500 V AC applies to the 450/750 V class, which is not this product. |
| Conductor Type | Class 5 flexible stranded copper to GB/T 3956 / IEC 60228 |
| Conductor Material | Annealed copper to GB/T 3956. The standard specifies conductor resistance and construction rather than a purity figure, so no purity percentage is claimed here. |
| Cross-sections | 0.75 / 1.0 / 1.5 / 2.5 mm² for 60227 IEC 53; 0.5 / 0.75 mm² for 60227 IEC 52 |
| Core Counts | 2 to 5 cores for 60227 IEC 53; 2 to 3 cores for 60227 IEC 52 |
| Insulation Resistance | Manufacturer test value, confirmed against the test report for the selected construction |
| Construction | |
| Insulation Compound | PVC/D compound per GB/T 5023.1 — the grade for flexible cables |
| Sheath Compound | PVC/ST5 compound per GB/T 5023.1 — the grade for flexible cables |
| Sheath Colour | Black, white or grey as standard; other colours to order |
| Core Identification | Standard colour code for the core count, with a green/yellow protective conductor where the construction includes one |
| Outer Diameter | Depends on core count and cross-section; confirmed on the construction drawing |
| Environment | |
| Max. Conductor Temperature | +70 °C continuous |
| Operating Temperature Range | −15 °C to +70 °C |
| Min. Installation Temperature | 0 °C recommended by the manufacturer — PVC becomes brittle below this and a cold bend can damage the insulation without visible signs |
| Bending Radius | 4 × outer diameter for fixed installation (manufacturer recommendation). GB/T 5023 does not set a bending radius for this cable type, so this is guidance rather than a standard requirement. |
| Flame Performance | Single-core vertical flame test to IEC 60332-1 as standard. This is not a flame-retardant product: ZA / ZB / ZC classes per GB/T 19666-2019 require a flame-retardant compound and are specified as ZR-RVV with the class stated. |
| Certification & Logistics | |
| Certification | CCC for this cable type under the PVC insulated cable scope of the China Compulsory Certification catalogue; certificate provided with the shipment. CE does not apply to a cable built to a Chinese standard — a European equivalent is quoted against the EN 50525 family. |
| RoHS | Compliance report available on request. RoHS is a substance restriction documented by a test report, not a product standard. |
| Standard Lengths | 100 m / 200 m / 500 m per coil; cut lengths on request |
| Packaging | Coil, reel or cut length |
| Customization | Core count, cross-section, sheath colour, cut length and customer marking |
| MOQ | 100 m — sample orders available |
| Lead Time | 5–15 working days; stocked configurations 3–5 days |
The two RVV voltage classes are what this specification is really about: 60227 IEC 53 at 300/500 V covers 0.75 to 2.5 mm² and is this product, while 60227 IEC 52 at 300/300 V covers 0.5 to 0.75 mm² in 2 or 3 cores and is supplied separately. The finished-cable withstand test follows the voltage class. Insulation and sheath compounds are the PVC/D and PVC/ST5 grades that GB/T 5023.1 assigns to flexible cables. The bending radius and the minimum installation temperature are manufacturer recommendations, because GB/T 5023 does not set either for this cable type. Final selection should be based on the circuit voltage, the installation method and the applicable local requirements.

Quality & Factory
Tested at the voltage class the cable is built to
Because RVV exists in two voltage classes, the release test follows the type rather than a single house figure.
- 1Incoming material control — copper conductor and the PVC/D and PVC/ST5 compounds are checked against specification before extrusion starts.
- 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 for the voltage class of the cable — 1500 V AC or 2000 V AC for 5 minutes — are measured and recorded.
- 4Finished-cable inspection — core identification, sheath surface, outer diameter and the printed marking including the type designation are checked before the coil is released.

FAQ
Questions buyers ask before ordering
RVV is the Chinese designation for a flexible PVC insulated and PVC sheathed multi-core cable: R for flexible (软), the first V for PVC insulation and the second V for the PVC sheath. It is defined in GB/T 5023.5-2008, the flexible cable and cord part of the GB/T 5023 series, which is equivalent to IEC 60227-5.
It depends on which RVV you are buying, and this is where most datasheets go wrong. 60227 IEC 52 is the light-duty type at 300/300 V, limited to 2–3 cores and 0.5–0.75 mm². 60227 IEC 53 is the ordinary-duty type at 300/500 V, from 0.75 to 2.5 mm² in 2–5 cores. A specification that lists 300/300 V and 2.5 mm² in the same table is describing two products, because the light-duty type does not reach that cross-section.
The extra P means screened. RVVP is the same flexible PVC construction with a copper wire braid screen over the laid-up cores, for circuits that need EMC protection — it is the Chinese counterpart of a CY screened control cable. RVV is unscreened and is for circuits where no screen is needed. If your circuit runs next to a drive or an inverter, ask for the screened version rather than accepting induced noise and chasing it later.
No. RVV is a general-purpose indoor cable: the PVC sheath is not UV-stabilised for permanent outdoor exposure, and the construction is not rated for direct burial or for wet locations. It is intended for conduit, trunking, ducts and equipment wiring in dry conditions. Tell us the environment and we will quote an armoured or XLPE insulated alternative rather than let a standard RVV cable be used where it will not last.
Core identification follows the standard colour code for the core count, with a green/yellow protective conductor where the construction includes one, so a 3-core cable is commonly brown, blue and green/yellow. Sheath colour is black, white or grey as standard, with other colours to order. Because the core code changes with the core count, the exact arrangement is confirmed on the construction drawing before production.
A maximum conductor temperature of +70 °C continuous, with an operating range of −15 °C to +70 °C. The manufacturer recommends not installing below 0 °C, because PVC becomes brittle when cold and a bend made at low temperature can damage the insulation without any visible sign at the time.
CCC applies to this cable type: PVC insulated cables rated 450/750 V and below to the GB/T 5023 series are within the China Compulsory Certification scope, and the certificate covering the ordered construction is provided with the shipment. CE does not apply to a cable built to a Chinese standard — CE marking is a European declaration against a European standard, so where a European equivalent is required the correct answer is the EN 50525 family, which we quote as a separate product rather than mislabelling a GB cable.
MOQ is 100 m with sample orders available. Stocked configurations ship in 3–5 days and made-to-order core counts, sections and colours in 5–15 working days. Standard supply is 100 m, 200 m and 500 m coils, with cut lengths, reels and customer marking on request. Because the type designation (IEC 52 or IEC 53) is printed on the cable and the drum, confirming the duty at inquiry stage avoids a labelling problem at site.
