Cable Specifications
Cable Srandards are the meaning of the number of cores and cross-sectional size of wire and cable representation. The main wire and cable products used in power systems are overhead bare wires, busbars (busbars), power cables (plastic cables, rubber cables, overhead insulated cables), branch cables (replacing some busbars), electromagnetic wires, and electrical equipment wires and cables for power equipment.
ZMS cables can be manufactured to the most stringent standards in the world, including BS, CSA, IEC, VDE, and UL. And if you need a cable to suit your application or a custom-made special cable, our technical team is at your service to meet the best requirements for your project.

Several Types of Commonly Used Cable Models and Their Use Occasions
VV Cable | Polyvinyl Chloride Insulation (VV Cable) PVC-sheathed power cables can be laid indoors, in tunnels, cable trenches, pipelines, and flammable and seriously corrosive places. |
YJV Cable | Cross-Linked Polyethylene Insulation (YJV Cable) Polyvinyl chloride sheathed power cable can be laid indoors, in tunnels and pipelines, and can withstand a certain laying draw through. |
ZR-VV Cable | Flame-Retardant Polyvinyl Chloride Insulation (ZR-VV Cable) The Flame-retardant PVC-sheathed power cable can be laid indoors, in tunnels, cable trenches, pipelines, and flammable and seriously corrosive places. |
ZR-YJV Cable | Flame Retardant Cross-Linked Polyethylene Insulation (ZR-YJV Cable) Polychlorinated ethylene-sheathed power cable can be laid indoors, in tunnels, and pipelines, and can withstand a certain amount of laying traction. |
NH-VV Cable | Fire-resistant PVC Insulation (NH-VV Cable) The PVC-sheathed power cable can be laid indoors, in tunnels, cable trenches, pipelines, and flammable and seriously corrosive places. |
NH-YJV Cable | Fire-Resistant Cross-Linked Polyethylene Insulation (NH-YJV Cable) PVC sheathed power cable can be laid indoors, in tunnels and pipelines, and can withstand certain laying traction. |
