High Quality! XLPE Insulated Overhead Cable
1.Application
Used for overhead power transmission and distribution lines of AC rated voltage up to and including 1kV or rated voltage 10kV.
2 Standard
Rated voltages up to and including 1KV aerial insulated cable implement the standard GB/T12527, Rated voltage 10KV aerial insulated cable implement the standard GB/T14049.
3 Application Properties
a)Rated voltage is up to and including 1KV, 10KV
b)The conductor long-term maximum working temperature: PVC and PE insulation should not exceed 70°C, XLPE insulation should not exceed 90°C.
c)During short circuit (maximum permanent time is not more than 5 seconds), the maximum temperature of cable conductor: XLPE insulation 250 °C, High-density polyethylene insulation 150°C
d) When laying the cable,minimum ambient temperature of laying should not be lower than -20°C.
e)The minimum bending radius: ≥20 (D+d) ±5%mm, D is the cable overall diameter, d is the conductor diameter.
4 Product Performance
A , Conductor DC resistance(at 20°C)conform to the stipulation of GB/T3956-2008.
B, AC Voltage Test: 3.5kV, lasting for 5min, without breakdown.
