Abstract

The utility model discloses a low-voltage five-core power cable of a corrugated conductor, which is internally provided with five copper-core conductors which are respectively and externally plated with a PVC (polyvinyl chloride) insulating layer, and an outer layer is packed with a lapping layer and an anti-flaming PVC outer sheath in sequence. The power cable is characterized in that the cross sections of four of the five copper-core conductors are corrugated copper-core conductors, and the other circular copper-core conductor is enclosed at the center by the four corrugated copper-core conductors jointly. After the shapes of the conductors are changed by the low-voltage five-core power cable of the corrugated conductor on the premise that all properties of a product meet the national standard GB/T12706-2008, the combination among the conductors (main wire cores) is more compact, and the outer diameter of a finished product is reduced, so that the difficulty of the problems of packing, transporting, paving and the like is reduced.

Description

Corrugation shape conductor low pressure 5-core power cable

Technical field

The utility model relates to power cable, particularly, is a kind of corrugation shape conductor low pressure 5-core power cable.

Background technology

In meeting the power cable of standard GB/T12706-2008, for conductor (master core) nominal cross 〉=70mm ²Five-core cable, usually the outer again mode of production of wrapping up in lapping layer, insulating barrier etc. after the round conductors of five outer plating insulating barriers are gathered in employing, its shortcoming is that the space is bigger between the conductor, compactness is poor, cause the external diameter of finished product to increase, problems such as packing, transport and lay has all been increased difficulty.

The utility model content

The purpose of this utility model is to provide a kind of corrugation shape conductor low pressure 5-core power cable, it is by the change to conductor shape, guaranteeing that all performances of product all meet under the prerequisite of standard GB/T12706-2008, make conductor (master core) combination each other tightr, the finished product external diameter reduces.

Concrete technical scheme of the present utility model is:

A kind of corrugation shape conductor low pressure 5-core power cable, inside is the copper core conductor of five outer plating PVC insulating barriers, skin is enclosed with lapping layer and flame-proof PVC oversheath from inside to outside successively, be characterised in that four in the described copper core conductor is that cross sectional shape is the copper core conductor of corrugation shape, they are centered around the center with an other circular copper core conductor jointly.

Corrugation shape conductor low pressure 5-core power cable of the present utility model, because wherein the cross sectional shape of four copper core conductors changes over corrugation shape, they just form the disc of a hollow together, be bonded to each other closely, again an other circular copper core conductor tightly is centered around the center, therefore five copper core conductor spaces each other are minimum, guaranteeing copper core conductor (master core) nominal cross (〉=70mm ²) under the constant prerequisite, reduced the external diameter of finished product greatly, make packing, the difficulty of problem such as transporting and laying all decrease, and all performances all meet standard GB/T12706-2008.

Description of drawings

With embodiment the utility model is described in further detail with reference to the accompanying drawings below.

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

Among the figure:

1, copper core conductor; 2, PVC insulating barrier; 3, lapping layer; 4, flame-proof PVC oversheath.

Embodiment

As shown in Figure 1, provided an embodiment of corrugation shape conductor low pressure 5-core power cable described in the utility model, its inside is the copper core conductor 1 of five outer plating PVC insulating barriers 2, skin is enclosed with lapping layer 3 and flame-proof PVC oversheath 4 from inside to outside successively, be characterised in that four in the described copper core conductor 1 is that cross sectional shape is the copper core conductor 1 of corrugation shape, they are centered around the center with an other circular copper core conductor 1 jointly.The corrugation shape conductor low pressure 5-core power cable of present embodiment since wherein the cross sectional shape of four copper core conductors 1 change over corrugation shape, they just form the disc of a hollow together, be bonded to each other closely, again an other circular copper core conductor 1 tightly is centered around the center, therefore five copper core conductor 1 spaces each other are minimum, guaranteeing copper core conductor 1 nominal cross (〉=70mm ²) under the constant prerequisite, reduced the external diameter of finished product greatly, make packing, the difficulty of problem such as transporting and laying all decrease, and all performances all meet standard GB/T12706-2008.

Claims

1. corrugation shape conductor low pressure 5-core power cable, inside is the copper core conductor of five outer plating PVC insulating barriers, skin is enclosed with lapping layer and flame-proof PVC oversheath from inside to outside successively, it is characterized in that: four in the described copper core conductor is that cross sectional shape is the copper core conductor of corrugation shape, and they are centered around the center with an other circular copper core conductor jointly.
