Product Description
ZR-KYJV is a 450/750 V flame-retardant control cable constructed with annealed copper conductors, XLPE insulation, flame-retardant filling, non-woven tape wrapping, and a flame-retardant PVC outer sheath.
It is designed for fixed control, monitoring, protection, and signal transmission circuits in industrial electrical systems. The XLPE insulation supports a maximum operating temperature of 90°C, while the flame-retardant PVC sheath is intended for installations where flame propagation needs to be limited.

Cable Construction
The cable is constructed in the following sequence:
Annealed Copper Conductor → XLPE Insulation → Flame-Retardant Filler → Non-Woven Tape Wrapping → Flame-Retardant PVC Outer Sheath
-
Conductor
Annealed copper conductors provide the electrical path for control, monitoring, protection, and signal circuits.
-
XLPE Insulation
XLPE insulation supports a maximum operating temperature of 90°C and provides electrical insulation between individual cores.
-
Flame-Retardant Filling
Flame-retardant filling material is used between the insulated cores to maintain cable shape and support the overall flame-retardant construction.
-
Non-Woven Tape
The wrapped layer helps hold the cable cores together and maintain a stable cable structure.
-
Flame-Retardant PVC Sheath
The outer PVC sheath provides mechanical protection and contributes to the cable's flame-retardant performance.
