Application
Prefabr branch cable is a new kind of low voltage distribution products, the prefab style can decrease the labor intensity greatly, shorten worktime, reduce cost greatly.The products is widely used at mid and high building highway, bridges, channels, high level workshop etc with its super performance.
Standards
The cables are manufactured according to the IEC60502 and JIS376A The insulation performance is much superior than IEC60502 The joint is tested according to the standard of GB9732

Operating Characteristics
a. The ambient temperature under installation should not be less than 0oC;
b. Min bending radius, for single-core, should not be less than 20 times the outer diameter; for multi-core, 15 times.
c. Max. continuous operating temperature of conductor, for XLPE insulated, should not exceed 90oC; for PVC insulated, 70oC. For a short circuit, the lasting time should not exceed 5s; and the temperature of conductor should not exceed 25oC for XLPE and 160oC for PVC.
