XLPE Insulation Control cable
It is used in controlling ,supervising loop and protecting circuit cases of A.C. rated voltage 450/750V or lower .
Executive standard : GB/T 9330-2008
Working Condition
1: Long-term working temperature allowed by cable conductor is 90℃.
2: Environment temperature for installation should be no less than 0℃, allowed bending radius is stipulated as follows : It should be no less than 8 times that of cable OD for unarmored cable ;It should be no less than 12 times that of cable OD for armored .
