Abstract

The utility model discloses an insulative flame retardant electric power cable. The insulative flame retardant electric power cable comprises power conductors and control conductors, wherein outer sides of the power conductors and the control conductors are respectively and sequentially wrapped in an insulation layer and a shielding layer, an elliptical rubber support is arranged between the two control conductors, outer sides are sequentially wrapped in a wrapping layer, an insulation layer and a waterproof layer to form control core wires, every two of the three control core wires are in tangential relations, the power conductors are respectively arranged between every two control core wires, outer sides are sequentially wrapped in a wrapping layer, a mica belt braiding layer, a water-blocking buffer layer and an outer sheath, and an outer surface of the outer sheath is coated with a wear resistance layer. The insulative flame retardant electric power cable has the good insulative effect, through employing the elliptical rubber support, improves tension capability and prolongs service life.

Description

Flame-resistant insulation power cable

Technical field

The utility model relates to cable technology field, relates in particular to a kind of flame-resistant insulation power cable.

Background technology

The power cable using at present all has insulating properties and resistance to corrosion, can effectively avoid phase fault and ground fault, in power distribution network, be widely used, but still there is the shortcomings such as insulation effect is good not, resistance to tension is poor, useful life is short in current power cable, need to improve.

Utility model content

The utility model object is exactly the defect in order to make up prior art, and a kind of flame-resistant insulation power cable is provided.

The utility model is achieved through the following technical solutions:

A kind of flame-resistant insulation power cable, include power conductor and control conductor, described power conductor and control conductor outside are all coated with insulating barrier and screen successively, two are controlled between conductor and are placed with oval rubber standoff and are coated with successively belting layer, insulating barrier and watertight composition formation control core in outside, control core tangent placement between two by three, control between core and be placed with power conductor and be coated with successively lapping layer, mica tape braid, water-blocking buffer layer and oversheath in outside at every two, on jacket outer surface, scribble wearing layer outside.

The utility model has the advantages that: the utility model insulation effect is good, by using oval rubber standoff, improve resistance to tension, extend the useful life of cable.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model.

Embodiment
