1. NH-YJV: fire-resistant cross-linked polyethylene insulated, PVC sheathed power cable
It can be laid indoors, in tunnels and in pipelines, and can enjoy a certain amount of laying traction, but the cables cannot accept external forces, and single-core cables are not allowed to be laid in magnetic material pipelines. If it is necessary to accept mechanical external force and wind the steel tape armor.
Suitable for occasions with special requirements, such as large-capacity power plants, nuclear power plants, subways, high-rise buildings, etc.

2. YJV: XLPE insulated, PVC sheathed power cable
It can be laid indoors, in tunnels, and in pipelines. It can enjoy a certain degree of laying traction, but the cables cannot accept external forces. Single-core cables are not allowed to be laid in magnetic material pipelines. If it is necessary to accept mechanical external force and wind the steel tape armor.

3. ZR-VV: flame-retardant PVC insulated, PVC sheathed power cable
It can be laid indoors, tunnels, cable trenches, pipelines, flammable and severely corroded places, but cannot accept mechanical external forces. If it is necessary to accept mechanical external force and wind the steel tape armor.
Features: When an open flame is burning, remove the fire source, and automatically extinguish within 12s.
