CN203520981U - Special cold resistant silicone rubber cable - Google Patents

Abstract

The utility model discloses a special cold resistant silicone rubber cable. The special cold resistant silicone rubber cable comprises an oversheath, a tape wrapping layer wrapping the oversheath, and at least one cable core which is disposed in the tape wrapping layer and is fastened by the tape wrapping layer, wherein the cable core is composed of a conductor layer and an insulation layer wrapping the conductor layer, and the oversheath and the insulation layer are both made of silicone rubber. The special cold resistant silicone rubber cable is quite small in resistance and high in roughness, and can prevent itself from being damaged during dragging. At the same time, the oversheath and the insulation layer are made of antifreezing materials so that the cable can be further prevented from being damaged when used in low-temperature environments.

Description

A kind of special type silicone rubber for cable that resists cold

Technical field

The utility model relates to cable technology field, relates in particular to the cold-resistant silicone rubber for cable of a kind of special type.

Background technology

Cable is the carrier that electric power is carried, its use scenes is boundless, also make in different application scenarioss not identical to the requirement of cable performance yet, particularly at some such as under low temperature environment, existing cable in use faces problems, such as pull and bending process in, cable easily damages, and, in low temperature environment, it is broken, more fragile, urgently to be resolved hurrily that cable jacket easily becomes.

Utility model content

The problem existing for prior art, the purpose of this utility model is to propose the cold-resistant silicone rubber for cable of a kind of special type, possesses higher flexibility and toughness, while using under low temperature environment, not fragile.

A kind of special type silicone rubber for cable that resists cold, comprise oversheath, and be coated on the belting layer in oversheath, and in belting layer and at least one group of cable core of being tightened by belting layer, described cable core consists of the insulating barrier of conductor layer and coating conductor layer, and oversheath and insulating barrier all adopt silicon rubber to make.

Belting layer adopts nonwoven fabrics to make.

Conductor layer adopts many stranded the forming of copper wire.

In belting layer, filling packed layer in the space between insulating barrier.

The utility model not only possesses less resistance, and toughness is strong, damaged in can preventing from pulling, and meanwhile, by oversheath and insulating barrier are used to freeze proof material, in the time of can further preventing from using in low temperature environment, cable be damaged.

Accompanying drawing explanation

Fig. 1 is the structural representation of the cold-resistant silicone rubber for cable of a kind of special type that the utility model proposes.

Embodiment

As shown in Figure 1, Fig. 1 is the structural representation of the cold-resistant silicone rubber for cable of a kind of special type that the utility model proposes.

With reference to Fig. 1, the utility model proposes the cold-resistant silicone rubber for cable of a kind of special type, comprise oversheath 1, and be coated on the belting layer 2 in oversheath 1, and at least one group of cable core of tightening in belting layer 2 and by belting layer 2, described cable core consists of the insulating barrier 3 of conductor layer 4 and coating conductor layer 4, and oversheath 1 all adopts silicon rubber to make with insulating barrier 3.

Adopt silicon rubber to make oversheath 1 and insulating barrier 3, can make the utility model overall structure possess higher anti-freezing property.

Belting layer 2 adopts nonwoven fabrics to make, and belting layer 2 possesses higher toughness, and possesses higher anti-freezing property.

Conductor layer 4 adopts many stranded the forming of copper wire, conductor layer 4 adopts copper material to make, possesses higher conductivity, simultaneously, adopt the many stranded conductor layers that form 4 of copper wire when possessing lower resistance, its toughness strengthens greatly, immediately under cryogenic conditions, also can make overall structure possess anti-performance, the not frangibility of pulling preferably.

In belting layer 2, filling packed layer 5 in the space between insulating barrier 3 outsides, the existence of packed layer 2 can make overall structure fuller.

The above; it is only preferably embodiment of the utility model; but protection range of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; according to the technical solution of the utility model and utility model design thereof, be equal to replacement or changed, within all should being encompassed in protection range of the present utility model.
