Abstract

The utility model discloses a non-shielded cable adopting a polyvinyl chloride sheath, which comprises a conductor, a wrapping layer, a cohesive polyvinyl chloride layer, a semi-conductive water-blocking buffer layer, a conductor insulating layer, a metal armor layer and an outer polyvinyl chloride layer which are sequentially arranged from inside to outside, wherein the conductor comprises a plurality of core bodies and water-blocking petroleum jelly filled between the core bodies and the wrapping layer, and the core insulating layer is arranged outside the core bodies. The conductor is fixed through the wrapping layer, meanwhile, the wrapping layer is made of non-woven fabrics and has a flame retardant effect, the inner polyvinyl chloride layer, the semi-conductive water-blocking buffer layer, the conductor insulating layer, the metal armor layer and the outer polyvinyl chloride layer outside the wrapping layer play multiple protection roles, and when the cable penetrates through a hole with the size equal to the outer diameter of the cable, the buffer layer can deform according to the size of the hole, so that the cable is prevented from being damaged.

Description

Adopt non-shielded cable of polyvinyl chloride sheath

Technical Field

The utility model relates to a non-shielded cable adopting a polyvinyl chloride sheath.

Background

The cable is a wire for transmitting electromagnetic energy and information and realizing electromagnetic energy conversion, and is very important in the mechanical field, the cable is generally cylindrical, when the cable passes through a hole with the size equivalent to the outer diameter of the cable, the surface layer of the cable is easy to damage, so that electric leakage or cable fracture is caused, and a very large potential safety hazard exists.

SUMMERY OF THE UTILITY MODEL

In view of the above problems, the present invention provides a non-shielded cable using a polyvinyl chloride sheath, which effectively solves the problems indicated in the background art.

The technical scheme adopted by the utility model is as follows:

the utility model provides an adopt non-shielded cable of polyvinyl chloride sheath, includes the conductor that sets gradually from inside to outside, around covering, cohesion chloroethylene layer, semiconduction buffer layer, conductor insulation layer, metal armor, outer polyvinyl chloride layer that blocks water, the conductor include many cores to and fill at the core and around the petroleum jelly that blocks water between the covering, the outside of core is equipped with the core insulation layer.

Preferably, the buffer layer is made of porous elastic material.

The porous elastic material can be selected from ceramic cellucotton, and has elasticity and high flame retardance.

Preferably, the conductor insulating layer and the core insulating layer are made of silica gel materials.

The insulating layer made of the silica gel material has good insulativity, and when the inner protective layer is seriously worn, the electric leakage of the core body is prevented.

Preferably, the wrapping layer is made of non-woven fabrics.

The conductor is fixed through the wrapping layer, meanwhile, the wrapping layer is made of non-woven fabrics and has a flame retardant effect, the inner polyvinyl chloride layer, the semi-conductive water-blocking buffer layer, the conductor insulating layer, the metal armor layer and the outer polyvinyl chloride layer outside the wrapping layer play multiple protection roles, and when the cable penetrates through a hole with the size equal to the outer diameter of the cable, the buffer layer can deform according to the size of the hole, so that the cable is prevented from being damaged.

Drawings

FIG. 1 is a schematic structural diagram of the present invention.

Detailed Description

The utility model is described in further detail below with reference to specific embodiments and with reference to the attached drawings.

Example 1

As shown in fig. 1, a non-shielded cable adopting a polyvinyl chloride sheath comprises a conductor 1, a wrapping layer 2, a cohesive vinyl chloride layer 3, a semi-conductive water-blocking buffer layer 4, a buffer layer 5, a conductor insulating layer 6, a metal armor layer 7 and an outer polyvinyl chloride layer 8 which are sequentially arranged from inside to outside, wherein the conductor 1 comprises a plurality of cores 11, and a water-blocking petroleum paste 12 filled between the core 11 and the wrapping layer 2, and a core insulating layer 13 is arranged outside the core 11.

The buffer layer 5 is made of porous elastic material.

The conductor insulating layer 6 and the core insulating layer 13 are made of silica gel materials.

The wrapping layer 2 is made of non-woven fabrics.

The metal armor layer is composed of cable armor steel wires arranged circumferentially.

The semiconductive water-blocking buffer layer is formed by wrapping a semiconductive water-blocking expansion belt, when the metal shielding layer and the plastic reinforcing layer are damaged and enter water, the semiconductive water-blocking expansion belt can expand in the presence of water, water is blocked in the longitudinal direction, further immersion of water is delayed and prevented, and rush repair is facilitated.

The outside of outer polyvinyl chloride layer 8 still is equipped with ultraviolet protection layer, ultraviolet protection layer can prevent that outer polyvinyl chloride layer 8 from being destroyed by the ultraviolet ray.

Finally, it should be noted that the above-mentioned list is only the specific embodiment of the present invention. Obviously, the present invention is not limited to the above embodiments, and many modifications are possible. All modifications which can be derived or suggested by a person skilled in the art from the disclosure of the present invention are to be considered within the scope of the utility model.
