PVC Insulated Power Cable
Standard and Scope of Application
The products can be produced and provided according to Chinese
standard GB/T12706-2002(equivalent to IEC 60505). The factory can
also manufacture the products that are based on British
Standard(BS) and other standards. In addition, under the
requirement of customers we can design and manufacture the products
that have 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.
Specific Property for Using
1. The long-time permissible working temperature of cable
conductive core is not more than 70C.
2. During short circuit(max permanent time is not more than 5
seconds), the max temperature of cable conductor is not more than
165C.
3. The difference level of laying cable is not restricted. When
laying the cable, ambient temperature is not lower than 0C.
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.
