Description
Technical field
The present invention relates to technical field of electric power, and in particular to a kind of cable.
Background technique
The transmitting of electricity is usually to realize by cable.Existing cable includes two parts, electric conductor and insulating layer,
For electric conductor for transmitting electric power, insulating layer is wrapped in the outer surface of electric conductor, prevents electric leakage.Cable in the prior art
Although having preferable electrical connection performance, since structure is complex, weight is larger, in aerial or hanging laying, has
It may be broken because itself overall weight cannot be born, and bendability and flexibility are also poor, are unfavorable in narrow operation
Wiring operation is carried out in space, in addition the performances such as wear-resisting, anti-tear, fire-retardant of existing cable are poor.And currently on the market
Mineral insulation heating cable makees thermal conductive insulator, seamless company as pyrotoxin, magnesia using single or more heating alloy
As sheath, the heating cable of this structure has apparent defect for continuous stainless steel or copper pipe, firstly, using magnesia as insulation
Body, magnesia are particularly easy to make moist, and cause the reduction of heating cable insulation performance.
Summary of the invention
In view of the problems of the above-mentioned prior art, the technical solution adopted by the present invention to solve the technical problems is to propose
A kind of cable, the cable are made of central core, insulating layer and restrictive coating；The restrictive coating is paperwrapped in the insulating layer
Outside, the central core is respectively positioned in the insulating layer；Insulating layer is formed a circle centered on the central core；The center
Sandwich layer is made of heating wire and resin filled core, and the insulating layer is flexible rubber powder bed.
Preferably, the compositing formula of the restrictive coating in parts by weight, including 46 parts of coal gangue particle, hydroxide
8 parts of aluminium, 7 parts of antimony oxide, 20 parts of ethylene propylene diene rubber, 1 part of modifying agent, 6 parts of vulcanizing agent, 2 parts of stabilizer, 1 part of stearic acid,
3 parts and 6 parts of cumyl peroxide of paraffin oil.
Preferably, the restrictive coating is the nylon material with self-lubrication.
Compared with prior art, the present invention provides a kind of cable, moisture resistance is strong, corrosion-resistant, anti-to collide with, is impermeable, pacifying
Full property is more preferable, and phenomena such as will not generate electric leakage in the energized state.Flexible rubber powder bed is to utilize common rubber pulverizing
Made of rubber powder, flexible rubber powder bed is filled in insulated wire cores respectively between the filled core, the shielded layer
Gap, so that the cable has certain anti-drawing and stability.The present invention solves and can not produce long length at this stage and add
The problem of electric heating cable, can customize the product of long length according to the actual requirement of client.Practical performance is strong, convenient for promoting.
Specific embodiment
The preferred embodiments of the present invention will be described in detail below so that advantages and features of the invention can be easier to by
It will be appreciated by those skilled in the art that so as to make a clearer definition of the protection scope of the present invention.
The invention proposes a kind of cable, the cable is made of central core, insulating layer and restrictive coating；The restrictive coating
It is paperwrapped in outside the insulating layer, the central core is respectively positioned in the insulating layer；Insulating layer is enclosed centered on the central core
At a circle；The central core is made of heating wire and resin filled core, and the insulating layer is flexible rubber powder bed.
In the above-mentioned technical solutions, the compositing formula of the restrictive coating in parts by weight, including coal gangue particle
