Abstract

The utility model relates to a high drainage cable. The high drainage cable comprises a conductor portion, an insulation layer, an inner sheath, an armor layer and an outer sheath, wherein the conductor portion is internally provided with a plurality of conductors, filler is filled in the gaps among the conductors, the insulation layer is wrapped around the circumferential sides of the conduction portion, the inner sheath is wrapped around the circumferential sides of the insulation layer, the armor layer is wrapped around the circumferential sides of the inner sheath, the outer sheath is wrapped around the circumferential sides of the armor layer, the armor layer comprises steel wires and copper wires, and the steel wires and the copper wires are distributed at outer circumferential wall of the inner sheath with intervals. According to the high drainage cable, the steel wires and the copper wires are distributed at the outer circumferential wall of the inner sheath with intervals to form a structure of the armor layer; the copper wires have characteristics of small resistance; drainage cross section of the cable is enlarged; drainage capability is further improved; the steel wires ensure tensile strength of the cable, so the high drainage cable has advantages of simple structure, reliable and practical performances, good drainage and long service life.

Description

A kind of high drainage cable

Technical field

The utility model relates to a kind of high drainage cable.

Background technology

The construction of cable generally comprises conductor part, and the insulating barrier that radially extends successively coating from conductor part, inner sheath, armour, oversheath, wherein conductor part inside is provided with gap between a plurality of conductors and each conductor and is full of filler is arranged, and the armature of cable layer that uses on the existing market generally adopts steel band to be coated on the inner sheath, steel band can effectively improve the radially resistance performance of cable, simultaneously also because the resistance of steel band is larger, and in the process that cable uses, because the magnetic field effect meeting that conductor part produces is so that armour produces faint electric current, therefore, the armour that steel band consists of can not effectively carry out the ground connection drainage to the electric current that this magnetic field effect produces, thereby affects whole service efficiency and the useful life of cable.

Summary of the invention

The purpose of this utility model is to overcome the defective of prior art, provide a kind of simple in structure, practical reliable and can Effective Raise the high drainage cable in useful life.

For achieving the above object, the utility model adopts a kind of high drainage cable, comprise conductor part, insulating barrier, inner sheath, armour, oversheath, wherein conductor part inside is provided with gap between a plurality of conductors and each conductor and is full of filler is arranged, described insulating barrier is coated on all sides of described conductor part, described inner sheath is coated on all sides of described insulating barrier, described armour is coated on all sides of described inner sheath, described oversheath is coated on all sides of described armour, wherein said armour comprises copper wire and steel wire, and described copper wire and steel wire are distributed on the described inner sheath periphery wall.

Concrete, described copper wire is preferably the copper cover aluminum structure.

The utility model is by the improvement to prior art, steel band in original armour is substituted with the mode that copper wire and steel wire are distributed on the inner sheath periphery wall, because copper wire has the little characteristic of resistance, and the drainage cross section that has therefore increased cable, and then raising drainage ability, and steel wire has been guaranteed cable tensile strength, therefore, cable sheath of the present utility model can effectively carry out the ground connection drainage to the electric current that the magnetic field effect of conductor part produces, simple in structure, practical reliable, and improved useful life greatly.
