6/6kv, 8.7/10kv, 26/35kv XLPE Insulated Power Cable Underground Use

Characteristics of Cable
1. Max Long-time operating temperature of PVC insulated cable is 70° C, XLPE 90° C
2. Installing temperature of cable should not be less than 0° C
3. Max short-circuit temperature is: PVC not exceed 160° C, XLPE 250° C, Not more than5 Sec.
4. Permitting bending radius cable: Not less than 10 D times (D: External diameter of cable)
5. Perfect chemical stability, resistant against acids, alkali, grease and organic solvents, and flamer retardant.
Type and Specifiction

Number of Cores & Nominal Cross-section Area

Installation:
1. The installation temperature should not over 20º C, If the ambient temperature is lower than 0º C, the cable should be preheated.
2. The bending radius of cable should not less than 8 times.
3. After installantion, the cable should with stand voltage test for 15min. 3.5kv D. C.

In air:
1. As the single core cable laying in parallel, the distance between the cable’s center is 2 times (for cables which cross section area of conductor ≤ 185mm2) and
90mm (for cables which cross sectional area of conductor≥ 240mm2)
2. Ambient temperature: 30º C
3. Max. Temperature of conductor: 70º C
4. Rating factors of current rating for ambient temperature:

Direct in ground:
1. When the single core cables are installed separately, the distance between the cable’s center is 2 times of the cable diameter.
2. Ambient temperature: 25º C.
3. Max. Temperature of conductor: 70º C.
4. Soil thermour resistivity: 1.0º C. M/w.
5. Depth: 0.7m
6. Rating factors under different ambient temp.:
