Quick Details
Product Details
1 Application:
The products can be produced and provided according to Chinese standard IEC 60505The factory can also manufacture the products that are based on the British Standard(BS) and other standards. In addition, under the requirement of customers, we can design and manufacture the products that have a special performance. The products are used in fixed laying on transmission and distribution electrical lines of 50 HZ AC rated voltage up to 6 kV.
2 Specific Property for Using
1.The long-time permissible working temperature of cable conductive core is not more than 70ºC.
2.During a short circuit(max permanent time is not more than 5 seconds), the max temperature of the cable conductor is not more than 165ºC.
3.The difference level of laying cable is not restricted. When laying the cable, the ambient temperature is not lower than 0ºC.
4.They have good chemical stability,and properties of acid resistance, alkali resistance, salt resistance, oil resistance, solvent resistance, and flame resistance.
5.Light weight, good bending property and easy installation and maintenance
