The conductor of the cable can be copper or aluminum and aluminum alloy.The number of cores can be single core, two core, three core, four core (including four core cross-sections and "Three big and one small" type with a small cross-section neutral core), five core (including five-core cross-sections,"Three big and two small" type with two small-section neutral wire cores,"Four big and one small" type with a small cross-section ground core).

The armor of the cable can be divided into steel wire armoured and steel tape armoured, etc., and adopts single core communication cable non-magnetic armour material.

According to the product is suitable for the occasion, insulating power cable can be flame retardant, fire-resistant type, cold type, etc.Flame retardant cables include bundle burning A, B, C, D, and low smoke halogen-free flame retardant series cables.

Cable conductor long-term allowed working temperature: 90 ℃.In case of short circuit (the longest duration is 5S), the highest temperature of XLPE insulation shall not exceed 250℃.

The laying temperature of the cable shall not be lower than 0℃.

XLPE power cable products can be produced according to IEC60502, BS 5467, HD 603, ICEA S 95-658 AS/NZS 5000, GB12706 and other product standards.


Compared with paper insulated cable and PVC insulated cable, cross-linked polyethylene insulated cable has excellent electrical properties, mechanical properties, thermal aging resistance, environmental stress resistance and chemical corrosion resistance, and simple structure, easy to use, not limited by laying drop, long-term working temperature high (90℃) and other advantages.


XLPE insulated power cable is suitable for fixed laying in AC 50Hz, rated voltage of 1 kV and below distribution line, used to transmit electric energy.


  1. Conductor
    The conductor material of the cable is composed of pure copper, aluminum and aluminum alloy.The conductor of the cable adopts solid core conductor, circular stranded conductor, circular compressed conductor and sector conductor.
  2. Insulation
    The insulation consists of an extruded XLPE.The insulation is extruded outside the conductor, and the insulation thickness conforms to the corresponding standards.
  3. Packed cable
    Multi-core cables are formed with appropriate fillers together with the cable core to make the cable circular. The entire cable core is usually wrapped with appropriate straps.
  4. Metal armor
    Metal wire armor is generally composed of galvanized round steel wire. The cable can withstand mechanical pressure and considerable tension, and is suitable for laying in vertical shafts, underwater and under falling or vertical conditions.
    Metal tape armor is generally composed of galvanized steel tape, the cable can withstand a certain mechanical impact and radial pressure.
    Under the armor, there are extruded PVC or PE isolation jackets for the cushion, or the inner lining layer is used to overlap the wrapping.
  5. Outer sheath
    The outer sheath of the cable is composed of PVC or PE.The thickness of the sheath conforms to the corresponding product standard.Outer sheath in addition to the special requirements, general to black.
