Power Cable
Standards
Products can be manufactured according to GB standard, IEC standard, ASTM standard, BS standard and DIN and other standard and customers` specific requirements.
Specification
1. Conductors: copper or aluminum.
2. Both armored and non-armored type power cables are available.
3. Voltage rating: 0.6/1kV 3.6/6kV 6/10kV 8.7/15kV 26/35kV.
4. PVC or XLPE sheathed.
5. Number of cable cores: one core (Single core),two cores(Double cores),three cores, four cores (Four Equal-section-area cores or three equal-section area cores and one smaller section area neutral core), five cores (Five equal-area cores or three equal-section-area cores and two smaller section area neutral cores).
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.
Number of Cores & Nominal Cross-section Area
| Number of Cores | 1 | 2 | 3 | 3+1 | 4 | 3+2 | 4+1 | 5 |
| Section Area (mm2) | 4 – 500 | 2.5 – 500 | 2.5 – 300 | 4 – 300 | 2.5 – 300 | 2.5 -300 | 4 – 300 | 2.5 – 95 |
Installation:
1. The installation temperature should not over 20ºC, If the ambient temperature is lower than 0ºC, 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. 35kv 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: 30ºC
3. Max. temperature of conductor: 70ºC
4. Rating factors of current rating for ambient temperature:
| Air temperature | 20ºC | 25ºC | 35ºC | 40ºC | 45ºC |
| Rating factors | 1.12 | 1.06 | 0.94 | 0.87 | 0.79 |
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: 25ºC.
3. Max. temperature of conductor: 70ºC.
4. Soil thermour resistivity: 1.0ºC. m/w.
5. Depth: 0.7m
6. Rating factors under different ambient temp.:
| Air temperature | 15ºC | 20ºC | 30ºC | 35ºC |
| Rating factors | 1.11 | 1.05 | 0.94 | 0.88 |
