Product description

1.Use:

 

It is suitable for overhead power lines with AC rated voltage of 35KV and below, and is used in places with high safety requirements such as towns, high-rise buildings and forest areas.

 

2、Use characteristics:

 

1. rated voltage is 1, 10KV.

2. cable long-term working temperature:

Polyvinyl chloride (PVC), polyethylene (PE) insulation should not exceed 70 ° C;

Cross-linked polyethylene (XLPE) insulation should not exceed 90 °C.

3. The maximum temperature of the cable conductor when short circuited (maximum duration not exceeding 5 seconds);

PVC insulation does not exceed 160 ° C;

Polyethylene insulation does not exceed 150 ° C;

XLPE insulation does not exceed 250 °C.

4. cable laying temperature should not be lower than -20 °C.

5. allowable bending radius of the cable:

▲1KV cable

Cable outer diameter D<25mm......4D;

Cable outer diameter D ≥ 25mm ... 6D.

▲10KV cable

Single core cable 20 (D + d) ± 0.5%.

Multi-core cable 15 (D+d) 0.5%.

Where: D-----the actual outer diameter of the cable (mm);

D-------The actual outer diameter (mm) of the conductor.
