Description
Technical field
The utility model relates to field of cable technology, particularly relates to a kind of power cable.
Background technology
Power cable has insulation property and certain resistance to corrosion, can effectively avoid phase fault and ground fault, be widely used in power distribution network.The insulating barrier of existing power cable easily occurs aging for a long time, causes the insulation property of cable to reduce, leaks electricity, the phenomenon such as short circuit, poor safety performance, and resistance to compression resistance to tension is poor, causes the useful life of cable short.
Utility model content
The utility model object is exactly the defect in order to make up prior art, provides a kind of power cable.
The utility model is achieved through the following technical solutions:
A kind of power cable, include ring-shaped rubber body, four semi-circular recesses are had uniformly in the outside of ring-shaped rubber body, master core is provided with at ring-shaped rubber body center, control conductor is placed with wherein in two semi-circular recesses, power wire core is placed with in two other semi-circular recesses, ring-shaped rubber body, master core, control conductor and power wire core form cable core jointly, are coated with crosslinked polyetylene insulated layer, aluminum-magnesium alloy wire woven shield, silver-plated B alloy wire woven shield and double-tape armor polyvinyl chloride oversheath in the outside of cable core successively; Described master core includes leading body, is coated with perfluoroethylene-propylene insulating barrier one, compound copper-plastics band lapping layer one, oval polyamide skeleton one and glass fiber tape lapping layer one in the outside of leading body successively; Described control conductor includes control conductor, is coated with perfluoroethylene-propylene insulating barrier two, mineral wool gasket for packing, compound copper-plastics band lapping layer two and glass fiber tape lapping layer two successively in the outside controlling conductor; Described power wire core includes power conductor, be coated with perfluoroethylene-propylene insulating barrier three, compound copper-plastics band lapping layer three, glass fiber tape lapping layer three and flower pattern skeleton in the outside of power conductor successively and form power wire core, described flower pattern skeleton is formed by four arc rubber skeletons are end to end.
Described leading body, control conductor and power conductor are all twisted by multiply tin-coated copper tow and form.
The utility model has the advantages that: the utility model is coated with perfluoroethylene-propylene insulating barrier, compound copper-plastics band lapping layer, oval polyamide skeleton and glass fiber tape lapping layer in the outside of conductor, insulation effect is good, not easily aging, use safety, flameproof effect is good, employs ring-shaped rubber body, novel structure, anti-pressure ability is strong, long service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
