1、 Product Description:
low smoke zero halogenFlame retardant shielded electronic computer cablePurpose: Low smoke halogen-free flame retardant computer cables have low voltage capacitance and low inductance, as well as good shielding and anti-interference performance, making their explosion-proof performance superior to general computer cables and control cables. They are suitable for use as transmission lines in distributed systems and automation detection and control circuits with explosion-proof requirements
2、 Usage characteristics:
Rated voltage: U0/U: 300/500V
High working temperature: Polyethylene insulation does not exceed 70 ℃, cross-linked polyethylene insulation does not exceed 90 ℃, and irradiated cross-linked polyethylene insulation does not exceed 105 ℃.
Low ambient temperature: -40 ℃ for fixed installation, -15 ℃ for non fixed installation.
Small bending radius: For unarmored cables, it should not be less than 6 times the outer diameter of the cable; Armored cables should have a temperature not less than 12 times the outer diameter of the cable.
