Concentric cables consist of a single or multi-core conductor with an insulation layer between the multi-core conductors that effectively prevents electromagnetic interference between the two conductors.

Concentric cables produced by ZMS are typical of the high quality of most cable insulation types.

Concentric cables are often used as energy supply cables and are most common in power distribution, panels, and street lighting.

ZMS Cable company mainly provides complete supply services for distributors and suppliers all over the world. Consulting services, purchasing services, transportation services, and after-sales services are included.

Description of ZMS Cable Products

Concentric conductor cables are suitable for use in dry and wet locations, they can be buried directly underground or used outdoors.

Their maximum operating temperature is 70°C (PVC or PE insulation) or 90°C (XLPE insulation) and their service voltage in applications is 600V.

The armor layer of the armored concentric conductor cable gives it better mechanical strength.

When it is buried in the ground, it improves the cable's ability to withstand pressure, reduces damage from external forces, and ensures the proper efficiency of the cable and linked equipment.
