Rated voltage 450/750 and polyethylene insulated cable Product Name:

Rated voltage 450/750 and polyethylene insulated cable


Suitable for AC voltage 450/750 and below power plant, household electrical appliances, machinery and telecommunications equipment, cables and wires
Flame retardant cables (wires) characteristics are not easy to catch fire or fire and flame spread is slow and controlled in a certain range, use high flame retardancy requirements of occasions. flame retardant cable (wire) according to GA306.1 standard is divided into class a, class b, class c and four level ⅰ, ⅱ, ⅲ, ⅳ, class a fire retardant performance optimal.
Refractory type cable (wire) of features is cable except can in normal of work conditions Xia transmission power, also can in burning of condition-like Xia still can keep must time of security run, its using in on cable refractory characteristics has high requirements of occasions. refractory cable (wire) by GA306.2 standard is divided into a, class, and b class II a category and ⅰ, and II, and III, and IV four a level, user can according to different of requirements select different of category of refractory cable.
1, Uo/U provide 450/750V, 300/500V, 300/300V
2, cable long-term allowable temperature
-90 model allowable working temperature does not exceed 90 ℃, short-term operating temperature reached 105 degrees; others allow working temperature should not exceed 70 ℃;
3, the laying temperature of the cables should not be less than 0 ℃
Bending radius: (b-series)
Cable diameter (d) is less than 25mm bending radius should not be less than 4D
Cable diameter (d) greater than 25mm or more allowed bending radius not less than 6D
4, flame retardant cable (wire), the flame should be burning through GA306.1 wire and cable testing.
5, fire-resistant cables (wires) of the fire resistance tests for fire resistance by GA306.2.
