XLPE Insulated Power Cable,XLPE Power Cable


Standards
GB/T 11017-2002: Power cables with cross-linked polyethylene insulation and their accessories for rated voltage of 110 kV.
IEC 60840:1999: Power cable with extruded insulation and their accessories for rated voltages above 30 kV(Un=m=36 kV)up to 150 kV(Um=170kV) Test methods and requirements
The cable can be applied to the neutral-point solid grounded power transmission line system with A.C. rated voltage 64/110kV(Um-126kV)

XLPE Insulated Power Cable,XLPE Power Cable

Properties of Application
1. During the normal operation of cables, the max permissible continuous operating temperature of conductor should not exceed 90°C.
2.Conductor short-circuit temperature should not exceed 250 °C(When max substaining period will not exceed 5 seconds).
3.The min permissible bending radius during the cable laying is normally 25 times of the diameter of cables.
4.Free from restrictions of level difference along the route during the cable laying.
5.Pre-heated is needed when the temperature is below 0 °C during the cable laying.

Performance

1, During the normal operation of cables, the max permissible continuous operating temperature of conductor shall not exceed 90 ℃
2, The allowed max temperature of conductor in case of short-circuit (last no more than 5 seconds) not exceed 250 ℃
3, The allowed min. bending radius. During producing and installing is 25 times of overall diameter of the cable.
4. The cable with aluminium sheath is suitable for no heavy corrsive situation and requiring to stand mechanical force. The cable with PVC out sheat is mainly applied in situation of demanding fire-proof and insulation of out sheat. The cable with PE outer sheath is mainly applied in high insulation required and cable directly into ground.
5. Pre-heated is needed when 0 ℃ during the cable laying.
