Application:
Used for power transmission and distribution line with voltage
rated at 35kV and below. Compared with PVC Insulated Power Cable,
XLPE power cable boasts not only characteristics of excellent
electricity, mechanism, heat and aging-resistant, environment
stress-resistant and chemical corrosion-resistant, but also simple
structure, light weight, no restriction by laying drop, and high
temperature allowance for long-term working.
Character:
1. Rated voltages U0/U: 450/750V
2. Permissible Max. continuous operating temperature of conductor:
3. PVC insulated: 70℃;XLPE insulated: 90℃.
4. Upon short circuit (Max. Duration time 5s) the Max.temperature
of conductor not higher than:
5. PVC insulated: 160℃; XLPE insulated 250℃.
6. Ambient temperature of installation not less than 0℃.
7. Preferred permissible bending radium:
8. For non-armored cable, not less than 6 times of cable diameter;
9. For armored or copper-tape-screened cable, not less than 12
times of cable diameter;
10. For screened flexible cable, not less than 6 times of cable
diameter.
