Abstract
The invention discloses a kind of construction of cable, including cable main, the cable main includes outer casing and inner core, the outer casing includes that what outermost flame retardant coating and innermost layer contacted setting with inner core encircles layer, described encircling is provided with bushing on layer, central filler material is provided between the bushing and flame retardant coating, the inner core is arranged in be encircled in layer and completely cuts off each other, layer is encircled to can be very good to separate cable inner core, prevent the short circuit phenomenon caused by collision after inner core is aging, increased safety coefficient, the service life of cable is improve simultaneously, cost is saved.
Description
Technical field
The present invention relates to electrical equipment technical field, it is related to a kind of construction of cable.
Background technology
Cable is made up of one or more insulation parcel conductors, superscribes metal again outside or rubber system is hard
Material.Power cable is used to transmit and distribute electric energy, typically in the underground power network in city, in the lead line in power plant, work
Used in power supply inside factory, the proportion that cable is accounted in power circuit is larger, transmission is played when in use and distributes high-power
The effect of electric energy.Therefore when cable is made, we need good preparation method and preferred structure, it is ensured that electric energy and power
Smooth transmission.
Other power cable plays a part of " backbone " in transmission of electricity, distribution, conducting process, but traditional
Power cable, the insulating barrier of its conductor is mostly individual layer, and this increased danger to a certain extent, because conductor is whole electricity
The core of power cable, once there is leaky, not only results in the loss on the energy, but also can bring serious accident,
, when the sheath of power cable is made, also most of use single-layer sheaths, its safety coefficient is not high, journey that its is wear-resistant in the market simultaneously
Degree does not reach requirement, it is impossible to is applicable the harsh hot environment of some conditions, has much room for improvement.
The content of the invention
（One）The technical problem to be solved
In order to overcome prior art not enough, it is proposed that a kind of high temperature resistant, the power cable of good insulation preformance.
（Two）Technical scheme
It is of the invention to be achieved through the following technical solutions：The present invention proposes a kind of construction of cable, including cable main, described
Cable main includes outer casing and inner core, and the outer casing includes that outermost flame retardant coating and innermost layer connect with inner core
That touches setting encircles layer, and described encircling is provided with bushing on layer, central filler material is provided between the bushing and flame retardant coating
Material, the inner core is arranged in be encircled in layer and completely cuts off each other.
Improved as one kind, the flame retardant coating forms using electro-insulating rubber is made, specific thickness be 0.12-10.1mm it
Between.
As a further improvement, the inner core is copper clad aluminum material.
（Three）Beneficial effect
The present invention has the advantages that relative to prior art：
A kind of construction of cable that the present invention is mentioned, its outer casing includes 4 Rotating fields, and outermost flame retardant coating can be effective
Play a part of hot-face insulation, the layer of encircling of innermost layer can be very good to separate cable inner core, prevent because inner core it is aging after
The short circuit phenomenon collided and cause, increased safety coefficient, while improve the service life of cable, save cost.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
1- cable mains；11- outer casing；12- inner cores；111- flame retardant coatings；112- encircles layer；113- packing materials；
114- bushings.
Specific embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
A kind of construction of cable as shown in Figure 1, including cable main 1, the cable main 1 include outer casing 11 and
Inner core 12, the outer casing 11 includes that what outermost flame retardant coating 111 and innermost layer contacted setting with inner core 12 encircles layer
112, described encircling is provided with bushing 114 on layer 112, and central filler material is provided between the bushing 114 and flame retardant coating 111
Material 113, the inner core 12 is arranged in be encircled in layer 112 and completely cuts off each other.
Wherein, the flame retardant coating 112 is formed using electro-insulating rubber is made, and specific thickness is between 0.12-10.1mm；It is described
Inner core 12 is copper clad aluminum material.
A kind of construction of cable that embodiments above is mentioned, its outer casing 11 includes 4 Rotating fields, outermost resistance to
Fire bed 111 can effectively play a part of hot-face insulation, and the layer 112 of encircling of innermost layer can be very good to separate cable inner core
Open, prevent the short circuit phenomenon caused by collision after inner core is aging, safety coefficient is increased, while improve the use year of cable
Limit, has saved cost.
Embodiment described above is only that the preferred embodiment of the present invention is described, not to structure of the invention
Think and scope is defined.On the premise of design concept of the present invention is not departed from, this area ordinary person is to technology of the invention
The all variations and modifications that scheme is made, all should drop into protection scope of the present invention, claimed technology contents of the invention,
All record in detail in the claims.
