ABC Cable (10kv and below)

1. Application

The cables are designed for aerial power lines with rated voltage Uo(Um) up to and including 10(12)kV.

2. Standard

GB/T14049 etc.

*We can also design and produce for special application requirement.

3. Product Properties

● Rated voltage is 10kV

● Max.Continuous permissive working temperature of conductor:

XLPE insulation should be not more than 90℃。

● Max. Temperature at short circuit (the longest continuous time is not more than 5S) XLPE insulation is 250℃。

● Installation temperature of cable should be not less than -20℃。

● Permissive bending radius of cable should be not less than 20(D+d) mm.

D -the actual overall diameter of cable ,mm;

d-the actual overall diameter of conductor ,mm.

● Insulation resistance of common insulation construction of aerial cable should be not less than 1500MΩ km, and insulation resistance of thin XLPE insulated construction of light aerial cable should be not less than 1000mΩ km.

● AC Voltage test: immerse cables in water at least for 1h before implementing testing voltage. (common insulation construction cable is 15KV, and thin XLPE insulated light cable is 12kV) The continuous time of test is 1min. The cable should not be breakdown.

● Partial discharge test: implementing AC Voltage 9kV on insulation shield cable. The discharge volume of cable should be not more than 20pc.
