Abstract

The utility model discloses a power transmission cable for laying pipeline. The power transmission cable comprises a plurality of conductors, and each conductor is sequentially wrapped up by an aluminum foil winding layer, a braid thermal insulation layer braided with ceramic fiber, a blanket, an inner winding thermal insulation layer formed by ceramic fiber band, insulation cores formed by silicone rubber insulating layers, wherein a plurality of insulation cores are twisted to form a cable core. A calcining mica tape winding layer, an adhesion layer, a rock wool band winding layer made of rock wool, and a general winding thermal insulation layer formed by double-layer ceramic fiber band are arranged outside the cable core, and an anti-tear silicone rubber oversheath layer is arranged outside the general winding thermal insulation layer. The power transmission cable is novel in structural design, and multilayer winding thermal insulation layers effectively prevents cable core from being damaged by heat in laying pipeline and prolong the service lifetime of the cable.

Description

A kind of pipeline laying power transmission cable
technical field:
The utility model relates to power cable, relates in particular to a kind of pipeline laying power transmission cable.
background technology:
In power circuit, the shared proportion of cable increases just gradually.Power cable be master in electric power system in circuit in order to transmission with distribute the cable product of high-power power, comprising 1-500KV and above various electric pressure, the power cable of various insulation.
Power cable needs laying installation sometimes in pipeline, and because pipeline is sometimes under the environment in high temperature, high temperature is relatively large to the damage of power cable, easily causes the melted by heat that insulate, and causes the faults such as short circuit, brings huge loss.
utility model content:
In order to make up prior art problem, the purpose of this utility model is to provide a kind of pipeline laying power transmission cable, rational in infrastructure, can improve greatly the self-protection ability of cable, has reliable and stable power delivery capabilities in hot environment.
The technical solution of the utility model is as follows:
Pipeline laying power transmission cable, it is characterized in that: comprise many conductors, every conductor is coated with aluminium foil lapping layer outward successively, the knitted thermal layer that the braiding of ceramic fibre silk forms, oxygen barrier layer, the interior wrapped thermal insulation layer of the wrapped formation of ceramic fibre strip, silicone rubber insulation layer forms insulated wire cores, the many mutual stranded bunchys of insulated wire cores form cable core, cable core is provided with calcining Mica tape layer outward, adhering layer, the rock wool belt lapping layer that rock wool material is made, the total wrapped thermal insulation layer of the wrapped formation of double-layer ceramic fabric strip, total wrapped thermal insulation layer is provided with tear-proof silicon rubber external sheath layer outward.
Described pipeline laying power transmission cable, is characterized in that: the ceramic fibre silk count of described knitted thermal layer is not less than 92%.
Described pipeline laying power transmission cable, is characterized in that: the wrapped rate of putting up of ceramic fibre strip of described interior wrapped thermal insulation layer is not less than 38%.
Described pipeline laying power transmission cable, is characterized in that: the wrapped rate of putting up of double-layer ceramic fabric strip of described total wrapped thermal insulation layer is not less than 45%.
The utility model has the advantages that:
The utility model structural design is novel, by the structural design of the wrapped thermal insulation layer of multilayer, can effectively stop the damage of the heat of laying installation in pipeline to cable conductor, has extended useful life.
accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
embodiment:
Referring to accompanying drawing:
Pipeline laying power transmission cable, comprise many conductors 1, the every outer aluminium foil lapping layer 2 that is coated with successively of conductor 1, the knitted thermal layer 3 that the braiding of ceramic fibre silk forms, oxygen barrier layer 4, the interior wrapped thermal insulation layer 5 of the wrapped formation of ceramic fibre strip, silicone rubber insulation layer 6 forms insulated wire cores, the many mutual stranded bunchys of insulated wire cores form cable core, cable core is provided with calcining Mica tape layer 7 outward, adhering layer 8, the rock wool belt lapping layer 9 that rock wool material is made, the total wrapped thermal insulation layer 10 of the wrapped formation of double-layer ceramic fabric strip, the outer tear-proof silicon rubber external sheath layer 11 that is provided with of total wrapped thermal insulation layer 10.
The ceramic fibre silk count of knitted thermal layer 3 is not less than 92%.
The wrapped rate of putting up of ceramic fibre strip of interior wrapped thermal insulation layer 5 is not less than 38%.
The wrapped rate of putting up of double-layer ceramic fabric strip of total wrapped thermal insulation layer 10 is not less than 45%.
