Low Smoke Zero Halogen Power Cable is a flame-retardant power cable featuring a copper conductor and XLPE insulation. As an LSZH type, it emits minimal smoke and no halogens during combustion, making it ideal for fire-sensitive environments such as high-rise buildings, indoor facilities, data centers, and public transit systems where human safety and low toxicity are top priorities
Construction and Material
Conductor
Manufactured from pure electrolytic copper for high conductance, low ohmic loss, and efficient energy transmission.
Insulation
Made of cross-linked polyethylene or PVC, offering robust dielectric performance, heat resistance, and durability against dampness, chemicals, and scratching.


Sheath
A rugged PVC or zero-halogen, low-smoke jacket that shields against mechanical stress, UV exposure, and severe operating conditions.
Core arrangement
Four conductors in one cable, allowing versatile power delivery, especially for three-phase networks with a neutral wire.
Application
Tall office and residential towers
Underground train stations and tunnels
Data centers and computer rooms
Schools, hospitals, and shopping malls

Key Features
Fire behavior: low smoke output and zero toxic acid gas emissions under fire conditions.
Thermal capability: XLPE-based insulation enables a maximum continuous conductor temperature of 90°C.
Conductor type: copper, offered in both solid and stranded configurations.
Packaging
Finished product + wooden barrel packaging
