Abstract
The utility model relates to a modified rubber isolating cable, mainly comprising a copper conductive wire core, an isolating layer, and an insulating layer. The aim of the modified rubber isolating cable is to solve the problem of the aging properties of insulating rubbers and reduce cost. The isolating layer is made of cellophane. As the cellophane has high temperature resistant grade and is not crisp after vulcanized and is in a complete tube shape, the isolating layer can completely satisfy the technological requirement of high-temperature vulcanization, and the isolating layer has the advantages of good isolating effect, small gas permeation rate, fire retardation, and low cost; while in use, the products are convenient to peel ends; the cellophane is the optimum material of the isolating layer. A shielding layer is made of the composite layer of aluminum foil and the cellophane, and the shielding layer has the advantages of low cost and good effect.
Description
The utility model relates to a kind of insulated cable, particularly a kind of modified model rubber-insulated electric wires and cables.
Rubber-insulated electric wires and cables is the product that is of wide application, though the structural shape of this series products is various, its primary structure element has following several: conductor wire core, insulating barrier, restrictive coating, screen and outer jacket.Because the aluminium surface is oxidation and conductive resistance rate height easily, so generally all use the conductive copper wire core.A lot of rubber-insulated electric wires and cables all require to reach useful life decades, therefore adopt the good sizing material of ageing-resistant performance, to guaranteeing that product quality plays crucial effect, the electro-insulating rubber that uses as the product electric insulation layer should have various good physical mechanicals and electric property, and is wherein even more important with electric property, ageing properties and moisture resistance properties.At present, to product quality influence bigger what await solving is the ageing properties problem of electro-insulating rubber.At the common directly lining of the conductive copper wire wicking surface of product electro-insulating rubber, since adopting the TMTD(tetramethylthiuram disulfide) be the no sulphur rubber of vulcanizing agent after, it is generally acknowledged in the no sulphur rubber because addition element sulphur not, so just avoided the chemical reaction between sulphur and the copper, so the zinc-plated requirement of conductive copper wire wicking surface often is cancelled.Facts have proved, with TMTD is the no sulphur rubber of vulcanizing agent, on the product that harsh output is come, chemical reaction between copper and the sizing material is also not obvious, but at room temperature behind storage or the use some months, the copper line surface overstrike then often appears, even adhesion mutually between rubber and copper cash, and this phenomenon runs down along with the growth of storage or service time.After deliberation, to be copper ion produced catalytic action to rubber aging to the essence of this phenomenon, impels the rubber accelerated ageing; Simultaneously copper ion has also been produced corrosiveness.This defective can have a strong impact on the quality of product.Evidence, in sulfidation, the copper ion on the copper cash can be moved in the electro-insulating rubber and be gone, and produces the accelerated ageing effect.In order to address this problem, people increase separator between conductor wire core and electro-insulating rubber, for example the paper separator, be coated with tin layer separator, nonwoven fabrics separator or polyester film separator, but facts have proved that it all is not the optimal isolation layer material, paper separator moisture absorption is stronger, electric property to rubber-insulated electric wires and cables has remarkable influence, and can go to sticks and staves when producing and rot, and can not satisfy the high temperature curing process requirement; Be coated with tin layer separator and cost an arm and a leg, make product cost very high; The nonwoven fabrics separator is too thick and moisture absorption is also stronger, neither desirable material; The polyester film separator is facile hydrolysis then, and the embrittlement that hardens can not satisfy the high temperature curing process requirement, and price is also high, causes product cost also to improve.So far, countries such as the U.S., Japan, Britain and West Germany yet do not find best insolated layer materials.In addition, now used screen often is made up of tincopper fuse wire braided armor and MP metallized paper lapping layer (be fitted on the paper constitute by aluminium foil), or form by tincopper fuse wire braided armor, semi-conducting rubber layer and semi-conductor adhesive strap lapping layer etc., but become higher, also have much room for improvement.
The purpose of this utility model is to provide a kind of modified model rubber-insulated electric wires and cables, solves the ageing properties problem of electro-insulating rubber, and its separator can satisfy the high temperature curing process requirement.
The purpose of this utility model also is to provide a kind of modified model rubber-insulated electric wires and cables, solves the higher problem of screen cost.
The utility model is to realize like this.A kind of rubber-insulated electric wires and cables mainly comprises the conductive copper wire core, wraps in the outer glassine paper separator of conductive copper wire core, wraps in the outer insulating barrier of glassine paper separator.
Further, also can be surrounded by restrictive coating outside insulating barrier, also can be surrounded by outside restrictive coating as the aluminium foil of screen and the composite bed of glassine paper, the outside also can be surrounded by outer jacket again.
Modified model rubber-insulated electric wires and cables of the present utility model provides a kind of new technical scheme to the electro-insulating rubber ageing properties problem that awaits for a long time solving, and a kind of new polymeric barrier layer materials also is provided, and effective cost is low.For solving the used glassine paper separator temperature resistant grade height of electro-insulating rubber ageing properties problem, high temperature vulcanized back glassine paper is embrittlement not, be complete tubulose, can satisfy high temperature vulcanized technological requirement fully, and its isolation effect is good, gas permeation rate is little, can be fire-retardant, cost is lower, and is convenient to shell head when rubber-insulated electric wires and cables uses, and is insolated layer materials best between conductive copper wire core and electro-insulating rubber.This new type rubber insulated wire cable can be used for various aspects such as general industrial and mining enterprises, electric power, railway, boats and ships, mine, oil, automobile, aviation, radio, building, agricultural and daily life.
