1, the scope of application |
|
This product is applicable to the exchange of rated voltage 35kv transmission distribution lines. A lightweight, structure simple, user-friendly, Kai damage small, chemical corrosion resistance
And the installation of high mechanical strength from the gap constraints, environmental stress tolerance, good performance and excellent resistance aging electrical performance characteristics. |
Second, the implementation of standards |
|
GB/Tl2706.1.3-2002 |
|
Third, the use of identity |
|
1. Long cable conductor temperature should be allowed to work no more than 90 degrees, short circuit (5s) conductor maximum temperature of 250 degrees; Laying environmental temperature should be no less than
0 ℃ 。
2. Cable laying cables to be installed to allow bending radius Chanxin Waijing not less than 15 times cable; Three core cable should be not less than 10 times cable Waijing. |
