Low-voltage overhead cable JKLYJ

Aerial cable
Product description



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.
