WDZN-RYJS wire and cable is a fire-resistant polyolefin insulated connection flexible wire. RYJS stands for cross-linked polyethylene absolute twisted-type connection cord. R- flexible wire, YJ- crosslinked polyethylene, S- twisted pair. R is the type and use code, YJ is the insulation type, and S is the characteristic. Its fire resistance meets the requirements of GB/Tl9666 class. The long-term working temperature of the wire conductor does not exceed 70℃; When laying cables, the ambient temperature should not be lower than 0 ° C. Suitable for power plants. Used in instrumentation, aerospace, electric power smelting, chemical industry, ships, vehicles, food machinery, tunnels, stations. The fire prevention system of high-rise buildings and other key parts is suitable for lines with rated AC voltage of 450/750V and below, as well as occasions with high fire safety requirements, which is conducive to fire suppression and loss reduction in the event of fire. The power supply line of the emergency power supply and fire alarm equipment, the power supply line of the emergency power supply to the signal lamp, and the power supply line of the emergency power supply to the ventilation and smoke exhaust equipment.
