Abstract
The invention discloses a power cable. The power cable comprises a cable main body. The cable main body comprises an external covering layer and internal cores. The external covering layer comprises a fireproof layer at the outermost layer and surrounding layers at the innermost layer and in contact with the internal cores. The surrounding layers are provided with linings. An intermediate filling material is arranged between the linings and the fireproof layer. The internal layers are arranged in the surrounding layers and are mutually isolated. The surrounding layers can well separate the internal cores of the cable, so that a short-circuit phenomenon caused by collision of aged internal cores is prevented, the safety coefficient is increased, the service lifetime of the cable is simultaneously prolonged, and the cost is saved.
Description
Technical field
The present invention relates to electrical equipment technical field, relate to a kind of power cable.
Background technology
Cable is made up of one or more insulation parcel conductors, superscribes metal or the hard material of rubber system outside again.Power cable is used for transmission and distributes electric energy, general to use in the underground electrical network in city, in the lead line in power plant, in the power supply of inside plants, the proportion that cable accounts in power circuit is comparatively large, plays a part transmission in use and distributes high-power power.Therefore when making cable, we need good manufacture method and preferred structure, ensure the smooth transmission of electric energy and power.
Power cable is in transmission of electricity in addition, distribution, play a part in conducting process " backbone ", but traditional power cable, the insulating barrier of its conductor is mostly individual layer, this adds danger to a certain extent, because conductor is the core of whole power cable, once generation leaky, not only can cause the loss on the energy, but also serious accident can be brought, simultaneously on market when making the sheath of power cable, also great majority use single-layer sheath, its coefficient of safety is not high, it is wear-resistant, and degree does not reach requirement, the hot environment of some condition harshnesses cannot be suitable for, have much room for improvement.
Summary of the invention
(1) technical problem that will solve
In order to overcome prior art deficiency, existing proposition is a kind of high temperature resistant, the power cable of good insulation preformance.
(2) technical scheme
Of the present inventionly to be achieved through the following technical solutions: the present invention proposes a kind of power cable, comprise cable main, described cable main comprises outer casing and inner core, described outer casing comprise outermost flame retardant coating and innermost layer contact with inner core arrange encircle layer, described encircling on layer is provided with lining, between described lining and flame retardant coating, be provided with central filler material, described inner core is arranged in be encircled in layer and completely cuts off each other.
Improve as one, described flame retardant coating adopts that electro-insulating rubber is made to be formed, and concrete thickness is between 0.12-10.1mm.
As further improvement, described inner core is copper clad aluminum material.
(3) beneficial effect
The present invention, relative to prior art, has following beneficial effect:
A kind of power cable that the present invention mentions, its outer casing includes 4 Rotating fields, outermost flame retardant coating effectively can play the effect of hot-face insulation, the encircling layer and cable inner core can well be separated of innermost layer, prevent the short circuit phenomenon caused because of the aging rear collision of inner core, add coefficient of safety, improve the service life of cable simultaneously, save cost.

1-cable main; 11-outer casing; 12-inner core; 111-flame retardant coating; 112-encircles layer; 113-packing material; 114-lining.
Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
A kind of power cable as shown in Figure 1, comprise cable main 1, described cable main 1 comprises outer casing 11 and inner core 12, described outer casing 11 comprise outermost flame retardant coating 111 and innermost layer contact with inner core 12 arrange encircle layer 112, described encircling on layer 112 is provided with lining 114, between described lining 114 and flame retardant coating 111, be provided with central filler material 113, described inner core 12 is arranged in be encircled in layer 112 and completely cuts off each other.
Wherein, described flame retardant coating 112 adopts that electro-insulating rubber is made to be formed, and concrete thickness is between 0.12-10.1mm; Described inner core 12 is copper clad aluminum material.
A kind of power cable that above specific embodiment is mentioned, its outer casing 11 includes 4 Rotating fields, outermost flame retardant coating 111 effectively can play the effect of hot-face insulation, the encircling layer 112 and cable inner core can well be separated of innermost layer, prevent the short circuit phenomenon caused because of the aging rear collision of inner core, add coefficient of safety, improve the service life of cable simultaneously, save cost.
Embodiment recited above is only be described the preferred embodiment of the present invention, not limits the spirit and scope of the present invention.Under the prerequisite not departing from design concept of the present invention; the various modification that this area ordinary person makes technical scheme of the present invention and improvement; all should drop into protection scope of the present invention, the technology contents of request protection of the present invention, all records in detail in the claims.
