Operating conditions for cable laying

When laying in the air, the center distance of single-core cables when laying in parallel: 185mm2 and below is twice the diameter of the cable; 240mm2 and above is 90mm.

Ambient air temperature: 30°C

The long-term maximum working temperature of the conductor: 90°C

Direct burial

1. When the single-core cable is laid without contact, the cable center distance is twice the cable diameter.

2. Soil temperature: 25°C.

3. The long-term maximum working temperature of the conductor: 90°C.

4. Soil thermal resistance coefficient: 1.0℃.m/W.

5. Direct burial depth: 0.7m.
