Description
1. Product Description:
Low smoke halogen free flame retardant shielding electronic computer cable uses: low smoke halogen free flame retardant computer cable has low voltage capacitance and low inductance, and has good shielding performance and anti-interference performance. Therefore, the explosion-proof performance is better than the general computer cable and control cable. It is suitable for the transmission system with low smoke, halogen free flame retardant circuits, such as distributed system and automatic detection and control system with explosion-proof requirements. Line.
Two. Characteristics of low smoke halogen free flame retardant shielded computer cable:
Rated voltage: U0/U:300/500V.
High working temperature: polyethylene insulation is not more than 70 degrees centigrade, XLPE insulation is not more than 90 degrees Celsius, radiation crosslinked polyethylene insulation is not more than 105 degrees Celsius.
Low ambient temperature: fixed at -40 C, fixed at -15 C.
Small bending radius: no armored cable should be not less than 6 times of the outer diameter of the cable; the armored cable should not be less than 12 times the external diameter of the cable.
