Description

Overhead insulated cable harness

The technical field is as follows:

the utility model relates to a cable harness, in particular to overhead insulated cable harness.

Background art:

in the primary stage of urban development, because the building and population density are low, the low-voltage distribution network uses bare wires, the bare wires need to have enough distance, and the wires are fixed on the porcelain insulator, so that interphase short circuit or ground flashover can not occur under normal conditions, and the safety problem is not great; along with the development of cities, sidewalks are greened, the population density is increased, and the accident rate of bare wires is increased; the road of the old city of China is narrow, the underground pipeline is crowded, the cost for developing the underground power cable system is high, and the technical difficulty is more; the overhead insulated cable occupies small space, even an electric pole can not be erected, and the overhead insulated cable is erected in a forest area safely and conveniently.

The existing overhead insulated cables with two or more cores need to distinguish A phase, B phase and C phase by using convex ridges, generally, the A phase is one convex ridge, the B phase is two convex ridges, and the C phase is 3 convex ridges; the spine and the wire core are distributed on the insulated wire core in parallel and then are twisted into a cable; because the transposition sinle silk is rotatory, and the convex ridge can be rotatory along with the rotation of sinle silk, and inside being twisted into the sinle silk, consequently can not be fine distinguish A looks, B looks, C looks sinle silk, has increased the degree of difficulty for laying in later stage.

The utility model has the following contents:

the utility model discloses the technical problem that will solve is: overcome prior art's not enough, provide an overhead insulated cable pencil, can be quick distinguish the A looks, B looks, the C looks of cable apart, reduced the radiation degree of difficulty, the convex ridge becomes 360 rotatory distributions simultaneously, can play fine protection insulation core's effect, avoids insulation core scratch, improves the quality of product, reduces the loss of production.

The utility model discloses a technical scheme who solves technical problem and take is:

the utility model provides an overhead insulated cable pencil, is including bearing core, A looks sinle silk, B looks sinle silk and C looks sinle silk, it is provided with the convex ridge to rotate respectively on the outer wall of A looks sinle silk, B looks sinle silk and C looks sinle silk.

Be provided with a convex ridge on the outer wall of A looks sinle silk, and this convex ridge is 360 rotatory settings on the outer wall of A looks sinle silk, the convex ridge of setting on A phase conductor core outer wall and the outer wall formula structure as an organic whole of A phase conductor core.

Be provided with two convex ridges on the outer wall of B looks sinle silk, and two convex ridges are 360 rotatory settings on the outer wall of B looks sinle silk, two convex ridges that set up on B phase line core outer wall and the outer wall formula structure as an organic whole of B phase line core.

Be provided with three convex ridges on the outer wall of C looks sinle silk, and three convex ridges are 360 rotatory settings on the outer wall of C looks sinle silk, three convex ridges that set up on C phase line core and the outer wall formula structure as an organic whole of C phase line core.

The utility model discloses an actively beneficial effect is:

1. the utility model discloses a with the rotatory winding of convex ridge on the sinle silk that corresponds, and rotatory being provided with a convex ridge on the A phase line core, rotatory being provided with two convex ridges on the B phase line core, rotatory being provided with three convex ridges on the C phase line core, when A looks sinle silk, B looks sinle silk and C phase line core transposition, we just can see the convex ridge through the side, can be very easy distinguish A looks, B looks, C phase line core, reduced the degree of difficulty of laying.

2. The utility model discloses a with the rotatory setting of convex ridge on the sinle silk that corresponds, when carrying out production, the insulating layer that can avoid the cable plays fine protection insulation core's effect because of scraping the damage that causes to ground, improves the quality of product, reduces the loss of production.

3. The utility model discloses because the rotatory distribution of backbone both can play the effect of keeping apart each sinle silk, still do benefit to the heat dissipation that the cable can be better in the use, reduce the emergence of potential safety hazard.
