2 Product Overview
The YY/CY/SY LSZH flexible control cable is designed for control circuits, signal transmission, and low-voltage power supply where fire safety is a priority. Featuring Low Smoke Zero Halogen (LSZH) insulation and sheath, it produces minimal toxic gas and low smoke in a fire, making it essential for public buildings, tunnels, and high-occupancy environments.
Available in three construction variants: YY (unscreened) for general-purpose control wiring, CY (tinned copper braid shielded) for EMC/EMI protection in electrically noisy environments, and SY (galvanised steel wire braid) for mechanical protection against impact and rodent damage. The Class 5 flexible stranded copper conductor per IEC 60228 provides excellent flex life and ease of installation.
The LSZH compound meets IEC 60754-1 for zero halogen and IEC 61034-2 for low smoke density, ensuring compliance with stringent fire safety regulations. The cable is suitable for installation in conduit, trunking, or cable trays in dry and damp indoor environments.
Manufactured to rigorous quality standards under the management of SORIVO, each cable is tested for conductor resistance, insulation integrity, and voltage withstand. For detailed company information, please visit sorivocable.com/about-us/.

5 FAQ
What does LSZH mean in control cables?
LSZH stands for Low Smoke Zero Halogen. These cables use a special polymer compound that does not emit halogen gases (such as chlorine or fluorine) when exposed to fire, and produces significantly less smoke than standard PVC cables. This improves safety in enclosed or populated spaces.
What is the difference between YY, CY, and SY LSZH cables?
YY is an unscreened cable for general-purpose control applications. CY has a tinned copper wire braid shield for EMC/EMI protection in electrically noisy environments. SY has a galvanised steel wire braid for mechanical protection against impact and rodents. CY provides signal integrity while SY provides physical protection.
Can CY LSZH cable be used for VFD motor connections?
Yes, CY shielded LSZH cable is suitable for VFD motor connections where EMI suppression is required and halogen-free performance is specified. For longer VFD cable runs, we recommend our specialised VFD cable with symmetrical earth conductors and higher braid coverage.
What is the temperature range for LSZH cables?
LSZH flexible control cables typically operate from -35°C to +85°C in fixed installation, and from -5°C to +70°C when flexing. These ranges may vary slightly depending on the specific LSZH compound formulation. Contact SORIVO for application-specific temperature data.
Is this cable suitable for outdoor installation?
Standard LSZH cables are intended for indoor use in dry or damp environments. For outdoor or direct UV exposure, specify the black UV-stabilised LSZH sheath option. For direct burial applications, armoured variants are recommended.
