35kv and below XLPE insulated power cables
35kv and below XLPE insulated
power cable applications:
35kv and below XLPE insulated power cables for fixed laying in the exchange of 50Hz, rated voltage 35Kv and below the power transmission and distribution lines for power transmission. Compared with the PVC power cable, the product not only has excellent electrical performance, mechanical properties, heat aging resistance, environmental stress resistance and chemical resistance of the ability, and the simple structure, light weight, Long-term high temperature (90 degrees) and so on.
Implementation of standards: The International Electrotechnical Commission IEC60502-1997 standard production.
XLPE insulated power cable name and application:
XLPE insulated PVC sheathed power cable: fixed laying in the air, indoor, cable channel, tunnel or underground
XLPE insulated PE sheathed power cable: fixed laying in the room, cable channel, tunnel or underground
XLPE insulated steel tape armored PVC sheathed power cable: fixed laying in a place with external pressure
XLPE insulated steel tape armored PE sheathed power cable: fixed laying in the place of external force often
XLPE insulated thin steel wire armored PVC sheathed power cable: laying fixed in a place that can withstand the tension
XLPE insulated thin steel wire armored PE sheathed power cable: laying fixed in a place that can withstand the tension
XLPE insulated crude steel wire armored PVC sheathed power cable: fixed laying in the water, shaft or required to withstand the tension of the place
XLPE insulated thick steel wire armored polyethylene sheathed power cable: laying fixed in a place that can withstand greater tension
1, the cable laying environment temperature not lower than 0 ℃, otherwise it must be preheated. Cable laying gap is not limited.
2, the laying of the minimum bending radius provisions are as follows: Where: D is the actual outer diameter of the cable, d is the actual outer diameter of the conductor)
Single-core cable: 20 (d + D) ± 5%;
Three-core cable: 15 (d + D) ± 5%.
3, short circuit (up to 5S) temperature shall not exceed 250 ℃
Sanheng As a Chinese first-class wire and cable production enterprises, mainly the production of power cables, control cables, PVC insulated cable, building wire, PVC insulated and sheathed cables, rubber cables, overhead cables, bare conductor 8 series can be divided into more than 50 varieties, subdivided into 1000 specifications.
