Abstract

Disclosed is an oil-proof and wear-resisting cable. The oil-proof and wear-resisting cable comprises conductors, insulating layers, isolating layers, conductor oil-proof layers, reinforcing parts, glass fillers, a filler, an inner sheath layer, an oil-proof layer, an armor layer and an outer sheath layer; each conductor is coated with the corresponding insulating layer; each insulating layer is coated with the corresponding isolating layer; each isolating layer is coated with the corresponding conductor oil-proof layer; the reinforcing parts and the glass fillers are distributed outside the conductor oil-proof layers; and the spaces among the inner sheath layer, the conductor oil-proof layers, the reinforcing parts and the glass fillers are filled with the filler; the oil-proof layer, the armor layer and the outer sheath layer are arranged on the inner sheath layer outwardly in sequence; the glass fillers are silicon dioxide glass fillers, the surfaces of which are coated with fibers; the filler is a water-blocking material; the conductor oil-proof layers and the oil-proof layer both adopt polyester films; and the outer sheath is prepared from polyethylene. Compared with the prior art, by adoption of the technical scheme, the cable is relatively high in wear-resisting and oil-proof characteristics, suitable for various wear-resisting and oil-proof occasions, long in service life, and safe and reliable.

Description

A kind of grease proofing wear-resistant cable

Technical field

The invention belongs to power cable technical field, it particularly relates to a kind of grease proofing wear-resistant cable.

Background technology

The similar rope that cable is typically by several or several groups of wires (per group at least two) are stranded Cable, mutually insulated between every group of wire, and be often twisted into around a center, whole outside is surrounded by height The coating of degree insulation.It is erected at aerial more or is mounted in underground, the bottom, for telecommunication or power Transmission. Wires and cables industry is the second largest industry that China is only second to automobile industry, product variety Service Efficiency and the country Occupation rate of market is more than 90%.Worldwide, the Chinese electric wire gross output value has exceeded the U.S., Become the first big electric wire producing country in the world.

Electric wire is of many uses, and different use occasions are widely different to its performance requirement.Most of cable Insulating materials, in addition to it must have higher insulaion resistance, dieletric strength or low dielectric loss, also Good physical and mechanical properties must be taken into account, such as tension, counter-bending, anti-vibration, antitorque.

Cable be usually used in Urban Underground electrical network, the lead line in power station, the in-line power of industrial and mining enterprises and Cross river, excessively extra large submarine transmission cable；Cable easily meets with erection process and pulls and roll over around cable Erection inconvenience and frangibility are easily caused in the case of too hard, it is not wear-resisting；It is simultaneously more severe in environment Easily oil and chemical reagent are met when used in environment and be corroded, so as to the service life for causing cable has Limit.

The content of the invention

In to solve the problems, such as background technology, the invention provides a kind of grease proofing wear-resistant cable.

The technical scheme is that：A kind of grease proofing wear-resistant cable, including conductor, insulating barrier, separation layer, The anti-oil reservoir of conductor, reinforcement, frit, inserts, inner restrictive coating, anti-oil reservoir, armor and outer shield Jacket layer；Insulating barrier wraps conductor, and insulating barrier outside is enclosed with separation layer, and the anti-oil reservoir of conductor will isolate Layer is wrapped, and reinforcement and frit are distributed in the anti-oil reservoir outside of conductor, inner restrictive coating and the anti-oil reservoir of conductor, Between reinforcement and frit be filled with inserts, inner restrictive coating be outwards followed successively by anti-oil reservoir, armor and External sheath layer, frit scribbles the silica glass material of fiber for appearance, and inserts is material water-proof material, The anti-oil reservoir of conductor and anti-oil reservoir are poly-vinegar film, and external sheath layer is made up of polyethylene.

As a result of above-mentioned technical proposal, compared with prior art, the present invention has preferably wear-resisting Grease proofing characteristic, is adapted to the wear-resisting and grease proofing of various occasions and uses, and long service life is safe and reliable.

Description of the drawings

Fig. 1 is a kind of structural representation of grease proofing wear-resisting cable of the present invention.

Specific embodiment

Embodiment

As shown in figure 1, a kind of grease proofing wear-resistant cable, including conductor 1, insulating barrier 2, separation layer 3, The anti-oil reservoir 4 of conductor, reinforcement 5, frit 6, inserts 7, inner restrictive coating 8, anti-oil reservoir 9, armour Dress layer 10 and external sheath layer 11；Insulating barrier 2 wraps conductor 1, the outside of insulating barrier 2 be enclosed with every Absciss layer 3, the anti-oil reservoir 4 of conductor wraps separation layer 3, and reinforcement 5 and frit 6 are distributed in conductor The outside of anti-oil reservoir 4, inner restrictive coating 8 and the anti-oil reservoir 4 of conductor, filling between reinforcement 5 and frit 6 There is inserts 7, inner restrictive coating 8 is outwards followed successively by anti-oil reservoir 9, armor 10 and external sheath layer 11, Frit 6 scribbles the silica glass material of fiber for appearance, and inserts 7 is material water-proof material, and conductor is prevented Oil reservoir 4 and anti-oil reservoir 9 are poly-vinegar film, and external sheath layer 11 is made up of polyethylene.

The present invention is not limited to above-mentioned preferred embodiment, and anyone should learn the enlightenment in the present invention Under the structure change made, it is every with of the invention with technical scheme as same or like, belong to Protection scope of the present invention.

Claims

1. a kind of grease proofing wear-resistant cable, it is characterised in that：Including conductor, insulating barrier, separation layer, lead The anti-oil reservoir of body, reinforcement, frit, inserts, inner restrictive coating, anti-oil reservoir, armor and oversheath Layer；Insulating barrier wraps conductor, and insulating barrier outside is enclosed with separation layer, and the anti-oil reservoir of conductor is by separation layer Wrap, reinforcement and frit are distributed in the anti-oil reservoir outside of conductor, inner restrictive coating and the anti-oil reservoir of conductor, Between reinforcement and frit be filled with inserts, inner restrictive coating be outwards followed successively by anti-oil reservoir, armor and External sheath layer, frit scribbles the silica glass material of fiber for appearance, and inserts is material water-proof material, The anti-oil reservoir of conductor and anti-oil reservoir are poly-vinegar film, and external sheath layer is made up of polyethylene.
