Abstract

The utility model relates to an electric wire and cable, comprising a wire with an insulator; the wire is wound with reinforcing ribs; a gap is left between adjacent reinforcing ribs; compared with the common electric wire and cable, when in dragging, the electric wire and cable are more wear-resistant, the gap is left between the reinforcing ribs so as to lead the radiating capability of the electric wire and cable to be stronger, the problem that the electric wire and cable are bounded by steel belts or steel wire meshes is overcome, bending is easier, the paving of the electric wire and cable at a bent position is more convenient, and the metal use amount is reduced, therefore, the cost is reduced.

Description

A kind of electric wire

Technical field

The utility model relates to a kind of electric wire, belongs to technical field of electricity.

Background technology

At present, general electric wire generally comprises lead, sheath, armour and outer jacket from inside to outside, the common wiring cable does not have armour, the general electric wire that does not have an armour in use, often occur galling, revealing skin, leak current fault, cause the lead of electric wire also very new, and sheath is aging in advance, directly have influence on the useful life and the personal safety of electric wire, cause the wasting of resources.

Electric wire installs the purpose of armour additional except mechanical protections such as enhancing tensile strength, compression strength increase the service life; the electric wire of armouring has certain external force resistance performance; the armouring of electric wire is made with steel band or steel wire usually; the steel-tape armouring electric wire normally is wrapped in around the lead two edge laps with two-layer at least steel band is vertical.

Because steel-tape armouring electric wire seamless unoccupied place coated steel band around the lead, therefore the thermal diffusivity of this electric wire is poor, and electric wire is when bending, and the insulating barrier of lead is pierced through by steel band easily, causes the electric leakage accident; Steel wire armor wire cable is to coat the layer of steel wire net around lead, causes the cost height of this electric wire, the complex process of production.More than two kinds of electric wires be subjected to the constraint of steel band or steel wire, cause not flexible, unusual difficulty when corner is laid.

The utility model content

The technical problems to be solved in the utility model is at above deficiency, provides a kind of cost low, wear-resistant, easy bending, the electric wire that heat-sinking capability is strong.

For solving above technical problem, the technical solution adopted in the utility model is as follows: a kind of electric wire is characterized in that: described electric wire comprises the lead with insulator, is wound with reinforcement on the lead, has the gap between the adjacent reinforcement.

Adopt above technical scheme, than general electric wire, more wear-resisting when dilatory, having the gap between the reinforcement makes the heat-sinking capability of electric wire stronger, and overcome the problem that is subjected to the constraint of steel band or steel wire, and easier bending, convenient when having the position laying wire cable of bending, reduce the use amount of metal, reduced cost.

As further improvement in the technical proposal:

Described reinforcement is the reinforcement that plastics are made.

Described reinforcement comprises two-layer, the protective layer that skin is made for plastics, and internal layer is an intensive aspect.

Reinforcement has plastic protective layer, can reduce the damage to lead.

Described intensive aspect is the intensive aspect that steel wire is made.

Described intensive aspect is the thread intensive aspect of nylon.

Adopt steel wire, nylon wire equal strength than higher material intensive aspect, can make the intensity of reinforcement higher.

Be provided with sheath between described reinforcement and the lead.Can guardwire, make the security performance of electric wire higher.

The outside of described reinforcement is provided with outer jacket.Can effectively protect electric wire on the one hand, make cable more attractive in appearance on the other hand.

The utility model adopts above technical scheme, compared with prior art, has the following advantages:

(1) adopts above technical scheme, than general electric wire, more wear-resisting when dilatory, having the gap between the reinforcement makes the heat-sinking capability of electric wire stronger, and overcome the problem that is subjected to the constraint of steel band or steel wire, and easier bending, convenient when having the position laying wire cable of bending, reduce the use amount of metal, reduced cost.

(2) reinforcement has plastic protective layer, can reduce the damage to lead; Adopt steel wire, nylon wire equal strength than higher material intensive aspect, can make the intensity of reinforcement higher.

(3) sheath can guardwire, makes the security performance of electric wire higher.

(4) outer jacket can effectively be protected electric wire on the one hand, makes electric wire more attractive in appearance on the other hand.

The utility model is described in further detail below in conjunction with drawings and Examples.
