Intrinsically safe explosion-proof circuit with distributed type instrument signal cable of this product for explosion dangerous situations and other explosion-proof safety requirements higher occasions in the petroleum, chemical, electric power, gas, mining and other transmission automatic control signals. The cable has a low capacitance, low inductance distributed instrument signal cable, referred to as intrinsically safe cable for DCS system, has excellent shielding performance and anti-jamming performance, so explosion-proof safety performance was significantly higher than that of general cable for DCS system and computer control cable.
