Flammable and explosive enterprises mainly use cable specifications and models

1. Explosion-proof and flame-retardant control cables

The application scope of control cables: They are suitable for signal transmission, control and measurement systems of electrical instruments and distribution devices with an AC rated voltage (U○/U) of 450/750V and below in industrial and mining enterprises such as metallurgy, power, petrochemicals, etc. Its rated voltage is :0.45/0.75kV. Common product models include :ZRIA-KVV,ZRIA-KYJV,ZRIA-KYJVP,ZRIA-KVVR,IAZR-KVVRP,IAZR-KVVP,IAZR-KVVP2,IAZR-KVVP22,IAZRKVVP32, and ZRIA-KVVP2-22. ZRKFV ZRKFF, ZRKFVP ZRKFVR, ZR KFFR, etc. The maximum long-term allowable operating temperature of the cable conductor: 90℃ for cross-linked polyethylene insulated cables, 70℃ for polyvinyl chloride insulated cables, 70℃ and 90℃ for low smoke zero halogen flame-retardant polyolefin insulated cables, and 150℃ to 250℃ for fluoroplastic insulated cables. Silicone rubber insulation is 180℃.

Ii. Flame-retardant and explosion-proof computer cables

The application scope of computer cables: Twisted pair shielded signal cables are one of the dedicated cables for electronic computer systems. They are urgently needed supporting products for modern industrial construction and are widely used in electronic computers, instruments and meters, various automatic detection equipment and other information transmission and control systems in factories, mines, enterprises and scientific research departments in the energy industry, metallurgical industry, petroleum and chemical industry, etc. It is especially suitable for computer distributed control systems, transmitting the detection and control of process variables in production facilities, as well as analog and digital signals. Common cable models include :ZRIA-DJYVP,ZRIA-DJYPVP, ZRIA-DJYP2VP2,ZRIA-DJYPV22, ZRIA-DJYP3VP3,ZRIA-DJYVP32, ZRIA-DJYP2VP2-22, etc. The temperature of polyvinyl chloride insulated cables is 70℃, that of cross-linked polyethylene insulated cables is 90℃, and that of fluoroplastic insulated cables is 150℃ to 250℃

Iii. Flame-retardant and explosion-proof coaxial cables

This flame-retardant and explosion-proof video coaxial cable is suitable for signal transmission connection feeders in video monitoring systems in the petroleum, chemical, fire protection, mining and underground industries. This series of flame-retardant and explosion-proof RF coaxial cables must be laid separately for application. This product has flame retardancy and shielding properties.

ZRIASYVPVP-75-3, ZRIASYVPVP-75-4, ZRIASYV-75-5, ZRIASYV-75-7, ZRIASYV-75-9, ZRIASYV-75-12,IAYV-50-3, IAYV-50-5,  IAYV-50-7, IASYV-50-9, IASYV-50-12

Main technical features

The characteristic impedance of the IASYV-75 series is 75Ω.

The characteristic impedance of the IAYV-50 series is 50Ω.

At 20℃, the insulation resistance of the cable shall not be less than 5000MΩ·km.

4. The flame retardancy of the cable has passed the single vertical burning test in MT386-1995.

5. Applicable environment and working conditions

The varieties of explosion-proof cables include control cables, signal cables, computer cables, coaxial radio frequency cables, etc., of IA grade. Under normal working conditions, when there is one or two faults in the circuit, the explosive gas mixture cannot be ignited. In type IA circuits, the operating current is limited to below 100mA and is suitable for use in chemical engineering, oil refining, shipping, etc.
