Abstract
The utility model discloses a wire and a cable for silicon-rubber insulation electric equipment, which comprises a conductor wire core which is composed of a conductor and an insulating layer wrapped outside the conductor. The periphery of the conductor wire core is wrapped with an insulating wrapping tape and a sheath layer of an outermost layer. Insulation of vulcanized-silicone rubber materials is adopted by the insulating layer, and a rubber sheath of the vulcanized-silicone rubber materials is adopted by the sheath layer. The utility model is a cable exclusively used for electrical equipment. Because the flexibility and the elasticity of silicone rubber are enhanced after the silicone rubber is valcanized, the utility model is especially suited to be laid at moving occasions and environment having higher requirements of external force impact. In addition, because inorganic silicone atoms are contained in the molecular structure of the silicone rubber, the heat resistance of the silicone rubber is higher than the heat resistance of usual rubber and plastics, working temperature can reach more than 180 DEG C and the silicone rubber also has excellent fire retardant effects after fire retardant is added. And thus, the utility model has many specific good characteristics that a conventional cable does not have.
Description
Technical field
The utility model relates to a kind of power cable, particularly relates to a kind of wire cable for silicon rubber insulation electrical equipment.
Background technology
Epoch are improving, and society is in development, and the people's quality of life has produced the variation of making rapid progress.Electric energy becomes indispensable a kind of important energy source in people's work and the life, and a new agenda has also been put in the transmission of electric energy.The main delivery means of self-evident present electric energy is an electric wire, and this has just proposed a new challenge to the electric wire production industry.For the paces that keep up with the times, the scientific research personnel of electric wire production industry will constantly research and develop the demand of product to adapt to people's work and to live that makes new advances.The main material of electric wire production industry product is alkene, hydrocarbon polymer now, and cheap, processability is good, but thermal endurance is relatively poor, general serviceability temperature has only 70-90 ℃, and produces a large amount of poisonous and harmful substances during burning, and personnel and facilities and equipment are formed harm for the second time.Along with society and expanding economy, improving constantly of science and technology, people are more and more higher with performance demands such as the heat-proof combustion-resistant of electric wire and safety to electrical equipment, the electric wire that occasions such as intensive public place of subway, boats and ships, power station programme-controlled exchange machine room, computer room and the various signs of human habitation and automatically controlled facilities and equipment are laid particularly, its security requirement is higher.Wire cable for silicon rubber insulation electrical equipment is a kind of heat-proof combustion-resistant clean and environment-friendly cable that I scientific research personnel of company develops according to the market demand.This cable electrical function admirable, heatproof combustion resistance is good, does not emit even also there is pernicious gas when high-temp combustion, has avoided secondary pollution.The SiO2 white product that the burning back generates still is attached on the conductor wire core, has kept the insulation property and the energising performance of cable.
Summary of the invention
In view of this, the purpose of this utility model provides a kind of wire cable for silicon rubber insulation electrical equipment of heat-proof combustion-resistant clean environment firendly.
The technical solution of the utility model is: a kind of wire cable for silicon rubber insulation electrical equipment, comprise conductor thread core, and this conductor thread core is formed by conductor with at the insulating barrier of conductor outer wrapping, at peripheral wrap insulate band of conductor thread core and outermost restrictive coating; This insulating barrier is the insulation of adopting the sulphurated siliastic material, and restrictive coating then is the rubber sheath that adopts the sulphurated siliastic material.To be that a plurality of conductor thread cores are stranded form this cable, and the gap between each conductor thread core is filled with gasket for packing and fills.
This product is to be exclusively used in the cable that electrical equipment is used.Because behind the silicon rubber vulcanization, pliability and elasticity improve greatly, so such cable is particularly suitable for the environment that is laid in mobile occasion and external impacts is had higher requirements.In addition, because of containing the inorganic silicon atom in the silicon rubber molecular structure, its thermal endurance is that rubber commonly used and plastics are incomparable, and working temperature can reach more than 180 ℃, also has splendid flame retardant effect behind the adding fire retardant.Therefore product has the not available good characteristic of many special normal cables as: high-and low-temperature resistance (can be at-60 ℃---180 ℃ of scopes in normal use), chemical corrosions such as acid and alkali resistance and good mechanical property etc., so behind this launch products, just extensively be used in the occasions such as circuit installation of the intensive public place of subway, computer room and the various signs of human habitation and automatically controlled facility and electronic equipment.Wire cable for silicon rubber insulation electrical equipment is a kind of product of high technology content, and production process is many, and manufacturing process complexity, its profit margin are very considerable, and its economic benefit is self-evident.Bring very high economic benefit can in the near future my company.
Description of drawings
Fig. 1 is the structural representation of wire cable for silicon rubber insulation electrical equipment of the present utility model;
Among the figure, symbol 1 is represented conductor, and symbol 2 is represented silicone rubber insulation layer, symbol 3 representative insulation bands, and symbol 4 is represented the silicone rubber jacket layer, and symbol 5 is represented gasket for packing.
Embodiment
Below in conjunction with drawings and Examples the utility model is described further.
As shown in the figure, a kind of wire cable for silicon rubber insulation electrical equipment comprises conductor thread core, and conductor thread core is formed by conductor (1) with at the insulating barrier (2) of conductor outer wrapping, at peripheral wrap insulate band (3) of conductor thread core and outermost restrictive coating (4); This insulating barrier is the insulation of adopting the sulphurated siliastic material, and restrictive coating then is the rubber sheath that adopts the sulphurated siliastic material.To be that a plurality of conductor thread cores are stranded form this cable, and the gap between each conductor thread core is filled with gasket for packing (5) and fills.
The utility model prepares conductor with general equipment such as wire drawing machine, bunching machine and pipe twisting machine in the industry, before extruding insulated single wire, carry out mixing earlier: various compounding ingredients (as: vulcanizing agent, pigment etc.) are mixed, put into mill and refine glue, after mixing, pull into little, put into extruder and extrude insulated wire cores with specific purpose tool, make its vulcanization crosslinking by curing tube after the depanning, insulated single wire.And then insulated single wire utilized stranding equipment boundling together, and extrude silicone rubber jacket again, and make its typing through vulcanization crosslinking, get product.
