- Description of the purpose and usage properties
XLPE insulation means to change the linear structure of polyethylene molecule into three-dimension network structure by applying the physical or chemical cross-linking process. After cross-linking, the mechanical, thermo-aging and anti-environment stress properties of insulation material have been greatly improved, which makes the cable have excellent electrical and anti-chemical properties.
The cable listed is applicable for power distribution and transmission line of with rated voltage up to and including 35kV.
The maximum permitted long-term operating temperature of the cable shall be 90℃, with the maximum short-circuit (within 5 seconds) temperature being 250℃. The ambient temperature of installation of the cable shall not be less than 0℃.
The permitted bending radius of single core armored cable shall not be less than 20 times of the outer diameter of the cable, 15 times for multi-core armored cable, 15 times for single core non-armored cable, and 12 times for multi-core non-armored cable.

Note: The optional flame-retardant or fire-resistant types of the cables listed are also available.
For single core power cable, aluminum tape or non-magnetic material instead of steel tape should be utilized for armoring.
The delivery length of the cable shall not be less than 100 meters. The short end not less than 20 meters shall be permitted in delivery, and the length of short ends shall not be more than 10% of the total length of each delivery.
Any delivery length shall be permitted in accordance with the mutual agreement of the purchaser and the manufacturer. |
