Standard and Application Scope
This product is manufactured based on the GB/T standard 14049-2008 and Q/ZJGG 01-2007. The copper or aluminum conductor with XLPE or HDPE insulated cable can be applied to the power supply system that the rated voltage is 10(12)kV or 20(24)kV.
Using Features
①The long-term maximum operating temperature of the conductor (cable
with supporting structure) is:
HDPE insulated cable: 75℃,
XLPE insulated cable: 90℃.
②When short circuit (the lasting time should not more than 5 seconds), the
maximum temperature of the conductor is:
HDPE insulated cable: 150℃ ,
XLPE insulated cable: 250℃.
③The minimum ambient temperature in laying is -20℃.
④The permitted bending radius of the cable should not be less than the diameter of cylinder that had been used in the bending test.
