Description

A kind of insulated cable

Technical field

The utility model relates to field of cable technology, in particular to a kind of insulated cable.

Background technique

Cable electriccable；Powercable: being usually by several or several groups of conducting wires form.Cable has electric power electric Cable, control cable, compensating cable, shielded cable, high-temperature cable, computer cable, signal cable, coaxial cable, fire-resisting cable, Cable for ship, mine cable, aluminium alloy cable etc..They are all made of sub-thread or stranded conductor and insulating layer, for connecting Connect circuit, electric appliance etc..The manufacture of wire and cable and the production method of most of electronic products are entirely different.Electronic product is logical Frequently with another part is assembled into component, multiple components refill and are made into separate unit product, product is measured with number of units or number of packages.Wire and cable It is with length for basic measurement unit.All wire and cables be all since conductor processing, conductor periphery layer by layer In addition insulation, shielding, stranding, sheath etc. and wire and cable product is made.Product structure is more complicated, and the level of superposition is more.

In addition, wire and cable refers to the wire rod for electric power, communication and associated transport purposes, it is conveying electric energy, transmitting letter Breath and progress electromagnetic conversion and the various motors of manufacture, electric appliance, the indispensable basic equipment of instrument institute.Our times resource day It is beneficial nervous, it is also extremely stringent to material used in electric wire, for the electronic material for lead frame, terminal, connector etc. For, the fundamental characteristics as product, it is desirable that high intensity and high electric conductivity or thermal conductivity have both.

With popularizing for power cable, cable fault rate also increases therewith.Cable often leads to electrical fire, surrounding Adjacent cable also destroys, and causes irremediable loss to entire electric system, is being bent, and flattens, and the deformation such as torsion is held It is also easy to produce mechanical damage, drain conditions occurs, cable insulation plastic layer is easy aging, and the service life is short, and service life is short.

Utility model content

For above-mentioned deficiency in the prior art, the utility model provides a kind of insulated cable, structurally reasonable, It is anti-aging, good flame resistance, good mechanical property.

In order to reach above-mentioned purpose of utility model, the technical solution adopted in the utility model are as follows: a kind of insulated cable, Be successively arranged respectively including oversheath and inner sheath, between the oversheath and inner sheath the first fireprotection layer, the first insulating layer and Metal net layer is uniformly provided at least three cores along center circumferential direction inside the inner sheath, outside the core respectively according to Secondary package is equipped with second insulating layer and the second fireprotection layer, and filling is equipped with asbestos between second fireprotection layer and inner sheath.

As improvement: being coated with erosion resistant coating outside the oversheath, the erosion resistant coating is fluorubber material.

As improvement: first fireprotection layer is calcium carbonate coating.

As improvement: first insulating layer is EP rubbers material.

As improvement: the metal net layer is copper material.

As improvement: the second insulating layer is fluoroplastics material.

As improvement: second fireprotection layer is epoxide resin material.

Advantage is the utility model compared with prior art: the first insulating layer uses the third rubber material, resists cold, high temperature resistant And environmental suitability is strong, weathering resistance, second insulating layer uses fluoroplastics material, more good flame resistance, electrically and mechanically chemically Can be good, and it is conducive to soldered wires, while copper net is equipped between inner sheath and oversheath, it is more tough and tensile, it is hardly damaged.

Detailed description of the invention

Fig. 1 is a kind of structural schematic diagram of insulated cable of the utility model；

The appended drawing reference table of comparisons:

1- oversheath, 2- inner sheath, 3- core, the first fireprotection layer of 4-, the first insulating layer of 5-, 6- second insulating layer, 7- Two fireprotection layers, 8- asbestos, 9- erosion resistant coating, 10- metal net layer.

Specific embodiment

Further illustrate specific embodiment of the present utility model with reference to the accompanying drawing.

As shown in Figure 1, a kind of insulated cable, including oversheath 1 and inner sheath 2, the oversheath 1 and inner sheath 2 Between be successively arranged the first fireprotection layer 4, the first insulating layer 5 and metal net layer 10 respectively, along center circumferential inside the inner sheath 2 Direction is uniformly provided at least three cores 3, successively wraps up respectively outside the core 3 and is equipped with second insulating layer 6 and the second fire prevention Layer 7, filling is equipped with asbestos 8 between second fireprotection layer 7 and inner sheath 2.

Erosion resistant coating 9 is coated with outside the oversheath 1, the erosion resistant coating 9 is fluorubber material.

First fireprotection layer 4 is calcium carbonate coating.

First insulating layer 5 is EP rubbers material.

The metal mesh layer by layer 10 be copper material.

The second insulating layer 6 is fluoroplastics material.

Second fireprotection layer 7 is epoxide resin material.

The utility model in the specific implementation, using multi-layer compound structure, increases by the first fireprotection layer between interior oversheath 4, the first insulating layer 5 and metal net layer made of copper 10, and erosion resistant coating 9 is coated in 1 outer layer of oversheath, under the action of fire-proof insulation Toughness and the service life for increasing cable simultaneously are successively arranged the second 6 layers of insulation of fluoroplastics material in the outer layer of core 3, increase It is powered on the electric property of cable, while more convenient soldered wires, 8 material of asbestos filled between the second fireprotection layer 7 and inner sheath 2 Material, further increases the insulation effect between core 3.

The foregoing is merely the preferred embodiment of the utility model patent, it is not intended to limit the utility model specially Benefit, all made any modifications, equivalent replacements, and improvements etc. within the spirit and principle of the utility model patent should all include Within the protection scope of the utility model patent.
