ZMS LSZH sheath cables also include PVC single-core AWA armored cables and XLPE multi-core SWA armored cables. 

This design is commonly used for auxiliary power cables in power grids and various environments. The included armor means that the cable can be buried directly into the ground to prevent accidental shock and damage.

ZMS cables offer a comprehensive range of LSZH sheathed cables, typically used in fixed installations such as wiring in buildings.

It is also used in applications where fire and smoke emissions could pose a potential threat to human health or critical equipment.

LSZH cables are different from PVC cables and cables made of other compounds.

When a cable catches fire, it can produce large amounts of dense black smoke and toxic gases. However, because LSZH cable is made of a thermoplastic material, it produces only small amounts of smoke and toxic gases, and it contains no acidic gases.

It makes it easier for people to escape from a fire or hazardous area. Therefore, they are often installed indoors, such as in public areas, other hazardous areas, or poorly ventilated environments.

Application of LSZH Sheathed Power Cable

These XLPE-insulated and LSZH-sheathed power cables are generally used for fixed installation.

Suitable for building wiring, especially in areas where smoke and fume emissions may cause a potential threat to life but not for burial in the ground, either directly or in ducts.

ZMS Power Cable Group mainly provides complete supply services of LSZH sheathed power cables for distributors and suppliers all over the world.
