Classification & Features

Types: Ordinary RVS line, flame retardant RVS line, fire-resistant RVS line, low smoke and halogen-free RVS line.

Features: RVS has the flame resistance of flame-retardant fire-resistant cables. Under the condition of direct flame burning, short-circuit and open-circuit failures will not occur within a certain time (not less than 3h), ensuring continued power supply for lighting and signal transmission, protecting personnel for safe evacuation, and helping to extinguish fires while reducing losses.

Applications

Suitable for power with AC rated voltage of 450/750V and below, household appliances, instruments, and telecommunications equipment. It can be used for lighting connections, internal wiring of machines, emergency power supplies, fire pumps, and elevator communication signal systems. Widely used in high-rise buildings, oil fields, power stations, mines, chemicals, and subways.
