Underground 3cores 4cores 5cores Armoured Power Transmission Cable

1. Product Application.

The main function of XLPE Insulated Power Cable is to transport electricity, which is suitable for use in power distribution networks or fixed installations for industrial equipments operating at rated voltage up to and including 0.6/1, 1.8/3, 3.6/6, 6/10, 8.7/10, 8.7/15, 12/20, 21/35, 26/35kV with alternating current(AC) 50Hz.This product is usually used under a normal used condition, which does not apply to some special conditions, such as overhead, underwater, ship, submarine, nuclear power station, etc.
XLPE insulated flame-retardant power cable, with good performance on preventing fire burning on the circuit, can avoid fire accidents and losses. It is suitable for used in the places where the cable needed to be fixed and installed at high density level, like subway, tunnels and high-rise buildings etc.
XLPE polyethylene insulated low-smoke zero-halogen flame-retardant power cables, a kind of environmental product, has good performance on flame-retardant, corrosion resistance and low-smoke, which is suitable to be laid and fixed in crowded places, such as subway, shopping mall or school etc.

2. Technique Features & Standard.

XLPE polyethylene insulated power cables, this product is manufactured by parasitical cross-linking procedure, the straight-chain polyethylene will be changed as network structure by use this method, which transformed thermoplastic material into thermosetting material. The working temperature is up to 90ºC, which can raise the cable current capacity highly. XLPE polyethylene insulated power cables, the product has good performance on electrical characteristic, heat resistance, chemical resistance, environmental stress cracking resistance and aging resistance, all which make the cable has a long useful life.

GB/12706-2008, IEC60502-1,IEC 60228,IEC60332 BS 5467,IS 1554 , IS 7098 ect.
we can also design and produce for special application requirement.

3.2 The rated Temperature of Conductor
a) The long-time operating temperature of conductor should not be higher than 90ºC
b) If the core is in short circuit, short circuit temperature of conductor should not exceed 160ºCnot more than 5sec.
3.3 Ambient Temperature
When installation, the ambient temperature should not be lower than 0ºC, otherwise the cable need be preheated.
