Control cable for intrinsically safe circuits
This product has low capacitance and low inductance, has excellent shielding performance and interference performance, so the explosion-proof performance is superior to general computer cable and control cable. It is suitable for circuits such as distributed systems and automatic detection and control systems with explosion-proof requirements. The transmission line for weak signals, rated voltage: 300/500V and 450/750V.
Execution standard: The enterprise standard is equivalent to BS5308-1986.
Use characteristics: cable conductor long-term allowable working temperature ≤ 70 ° C (cross-linked polyethylene ≤ 90 ° C, heat resistance 105 ° C ≤ 105 ° C); cable laying environment temperature ≥ 0 ° C; minimum bending radius when laying cables should be ≥ cable 6 times the diameter, armored and copper tape shielded cable should be ≥ 12 times the outer diameter of the cable.
