■ Specifications

►Products application
XLPE polyethylene insulated power cables, This product is applicable to being fixedly laid on the transmission and distribution line of alternative current rating 50Hz and rated voltage up to 6/35 kV with the use for power transmission, which is applied to the range of distribution network, industrial equipments, high electricity consumption places etc.
XLPE polyethylene insulated flame-retardant power cables, The product has good performance on preventing fire burning on the circuit, which can avoid fire accidents and losses. The products can be used in subway, tunnels and high-rise buildings etc.
XLPE polyethylene insulated low-smoke zero-halogen flame-retardant power cables, The environmental product has good performance on flame-retardant, corrosion resistance and low-smoke, which is suitable to be laid in crowded places, such as subway, shopping mall or schools etc.
This product is the normal used cable, not suitable for some special places, such asunder water, ship, nuclear station, etc.

►Technique features
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 90℃, 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.
XLPE polyethylene insulated low-smoke zero-halogen flame-retardant low-smoke zero-halogen flame-retardant power cables; the product is a new environmental protected cable with good flame-retardant performance, which just releases few poisonous and corrosive gases. The product has good performance on electrical characteristic, heat resistance, chemical resistance, environmental stress cracking resistance and aging resistance, all which makes the cable has a long useful life.
The product characteristic is simple structure, short production period, easy installation and maintained, especially there is no limit of head drop during the cable laying.

►Operating characteristics
1. Rated Voltage
Rated Voltage of cable U0/U(Um),as follow:
U0/U(Um)=3.6/6(7.2)-6/6(7.2)-6/10(12)-8.7/10(12)-8.7/15(17.5)-12/20(24)-18/30(36)-21/35(40.5)-26/35(40.5)kV。
2. The rated temperature of conductor
The maximum assigned temperature of the cable conductor is 90℃.
During having a short circuit, lasting less than 5 seconds, the maximum temperature of the cable conductor shall not be above 250℃.
3. Ambient temperature for laying
The ambient temperature for laying shall be above 0℃, otherwise the cable need be preheated.
4. The bend radius
The minimum bend radius of the cable see the table 2

Table2 The minimum bend radius of the cable

Item Single -core Three -core
Unarmored Armored Unarmored Armored
Minimum bend radius of the cable in course of installation. 20D 15D 15D 12D
The minimum bend radius of the cable close to the junction box and terminal 15D 12D 12D 10D
Note: D is outer diameter of the cable


►1. Laying
There is no limit of head drop during the cable laying.
The cable may be laid in indoor, outdoor, air and soil. The cable may be immersed in water locally.
The cable may be laid in tunnel, pipe, trench, conduit and on cable bridge. The armored cable can be laid underground, and the wire- armored cable can be laid vertically.
The single core cable mustn't be laid in the magnetic metal pipes.
The environment of cable laying shall be in good heat dissipation condition.

►2. The requirements on transportation and storage
The cable reels shall not be delivered and stored in flat state.
It is strictly forbidden to push the cable reel from the high level in order to prevent the cable from damages
If the cable should be used sectionally, the head of the cable must be sealed in order to prevent water intake.
