Abstract

The utility model discloses a wire and cable technical field's an resistant oily high temperature cable, including the outside wrapped four-layer sheath of cable core conductor and cable core conductor, four layers the sheath is insulating layer, interior sheath, weaving layer, restrictive coating by interior pouring outer in proper order, be provided with mineral packing between insulating layer and the interior sheath, be provided with the tensile between interior sheath and the weaving layer and fill, be provided with the non-woven fabrics between weaving layer and the restrictive coating, solve the cable and often use under some abominable operating mode conditions, often need the cable to have good resistant oil, high temperature resistance ability. Oil immersion can cause cracking of the cable surface, affect the performance of the cable and cause interruption of cable transmission; the high temperature inside the automation equipment often leads to the shortening of the service life of the cable, thereby causing the short circuit of the cable and causing the problem of the damage of the electric appliance.

Description

Oil-resistant high-temperature cable

Technical Field

The utility model relates to a wire and cable technical field specifically is an resistant oily high temperature cable.

Background

A cable is an electrical energy or signal transmission device, usually consisting of several or several groups of conductors, usually a rope-like cable twisted from several or several groups of conductors (at least two per group), each group of conductors being insulated from each other and often twisted around a center, the whole being covered with a highly insulating covering. The cable has the characteristics of internal electrification and external insulation.

With the large number of applications of automation equipment in modern industry, cables are often used under some severe working conditions, and the cables are often required to have good oil resistance and high temperature resistance. Oil immersion can cause cracking of the cable surface, affect the performance of the cable and cause interruption of cable transmission; the high temperature inside the automation equipment often leads to the shortening of the service life of the cable, thereby causing the short circuit of the cable and causing the damage of the electric appliance. Therefore, it is an urgent task to improve the service life and reliability of the cable.

Based on this, the utility model designs an resistant oily high temperature cable to solve above-mentioned problem.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an resistant oily high temperature cable to the cable that proposes in solving above-mentioned background art often uses under some abominable operating mode conditions, often needs the cable to have good resistant oily, high temperature resistance ability. Oil immersion can cause cracking of the cable surface, affect the performance of the cable and cause interruption of cable transmission; the high temperature inside the automation equipment often leads to the shortening of the service life of the cable, thereby causing the short circuit of the cable and causing the problem of the damage of the electric appliance.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an resistant oily high temperature cable, includes the outer wrapped four layers sheath of cable core conductor and cable core conductor, four layers the sheath is by interior pouring outer insulating layer, interior sheath, weaving layer, restrictive coating in proper order, insulating layer and interior sheath be provided with the mineral and fill, be provided with the tensile between interior sheath and the weaving layer and fill, be provided with the non-woven fabrics between weaving layer and the restrictive coating, solve the cable and often use under some abominable operating mode conditions, often need the cable to have good resistant oily, high temperature resistance. Oil immersion can cause cracking of the cable surface, affect the performance of the cable and cause interruption of cable transmission; the high temperature inside the automation equipment often leads to the shortening of the service life of the cable, thereby causing the short circuit of the cable and causing the problem of the damage of the electric appliance.

As a further scheme of the utility model, the cable core conductor is the superfine smart hank anaerobic copper wire of stranded for the transmission effect of cable is better, and is anti-interference better.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the utility model has the advantages of simple structure, reasonable in design, it plays fabulous thermal-insulated to fill the mineral substance filling layer, prevent fires, multiple action such as fire-retardant and insulation, interior sheath has adopted the polyurethane material simultaneously, can protect the cable to use under the environment of immersion oil, can effectually prevent the cable surface fracture, the tensile ability of cable has been increaseed simultaneously, can let the environment that cable adaptation oil is many, the application range of cable has been enlarged, the life of cable has been improved greatly, the restrictive coating adopts butyronitrile material not only to improve the holistic high temperature resistance ability of cable, and dual grease proofing effect has been played, can guarantee that the cable uses under the environment of immersion oil.

Drawings
