Main technical features

1. IASYV - 75 series of characteristic impedance is 75 Ω;

2. IAYV - 50 series of characteristic impedance is 50 Ω;

3. At 20 ℃ insulation resistance of cable should be no less than 5000 m Ω · km;

4. Flame retardancy of the cable passed single vertical combustion test in mt386-1995;

5. Applicable environment and working conditions,

Explosion-proof cable varieties have control cable, signal cable, computer cable, coaxial radio frequency cable and other IA grades. Explosive gas mixtures cannot be ignited when there is one or two faults in the circuit under normal working conditions. In the IA circuit, the working current is limited below 100mA, suitable for chemical industry, oil refining, ship, etc.

Class IB: explosive gas mixtures should not be exposed to alene under normal operating conditions and in the presence of a fault in the circuit. In the IB circuit, the operating current is limited to less than 150mA, suitable for mine and explosion-proof equipment.
