Description
Technical field
The utility model relates to the construction of cable of a kind of protection against rodents, termite-proof, fire prevention, explosion-proof, waterproof, belongs to the cable technology field.
Background technology
The cable of the existing signal transmission that is used for industry automation control systems such as metallurgy, the energy, electric power and military project, detecting instrument, instrument mainly is made of the wrapped flame retardant coating of mica, insulating barrier, oxygen barrier layer and sheath etc. on conductor and the conductor, and the phenomenon that cable is bitten by termite and mouse often takes place.Cable is bitten to requirement has fire prevention simultaneously, occasion explosion-proof, waterproof has caused threat again, exists certain potential safety hazard.Cable is because of being bitten, and waterproof, fire prevention, explosion-proof performance are poor, and the security incident of the initiation fire that is short-circuited is of common occurrence, has caused massive losses to the people's lives and property.Therefore, developing that a kind of termite-proof and mouse etc. bites, have fire prevention, waterproof, explosion-proof high performance cable simultaneously, is a urgent task of cable R﹠D institution and manufacturing enterprise.
The utility model content
The purpose of this utility model is to overcome the deficiency that existing cable exists, and a kind of protection against rodents, termite-proof, fire prevention, explosion-proof, five anti-instrument private cables that waterproof is one are provided.
The purpose of this utility model is to realize like this, five anti-instrument private cables, comprise double-deck mica flame retardant coating on conductor and the conductor, insulating barrier, oxygen barrier layer and sheath, it is characterized in that being provided with by the outer wrapped double-deck mica flame retardant coating of copper core conductor, extrude the line group of the insulated wire cores pair twist that gathers full second propylene insulating barrier and the cable core that line group pair twist constitutes, the line group is provided with metal and moulds and be with wrapped phase-splitting screen, wrapped water blocking layer and channelizing line, cable core is provided with the gasket for packing that blocks water, wrapped water blocking layer, metal is moulded and is with wrapped total screen, total channelizing line, in on total screen, being provided with, oversheath and armouring oxygen barrier layer are in the armouring oxygen barrier layer is arranged on, in the middle of the oversheath.
Described conductor is the high-quality copper free wire.Double-deck mica flame retardant coating is that two-sided synthetic mica tape is wrapped, and Duplication is answered the lapping layer more than 〉=40%.Channelizing line is 0.5mm
2Stranded copper wire or tin-coated copper tow.The armouring oxygen barrier layer is the vertical bag of the embossing steel band armour of continuous welding.The gasket for packing that blocks water is filled between the wrapped water blocking layer on cable core and the cable core.Metal is moulded band and is moulded band or plastic-aluminum band for copper.Described oversheath is the flame-proof polyvinyl chloride sheath that contains the alkyl copper of protection against rodents, anti-ant.
The utility model is rational in infrastructure simple, manufactures easily, and serviceability is good.Cable design high-quality copper free wire conductor, double-deck mica flame retardant coating, wrapped copper mould band or plastic-aluminum band phase-splitting shielding and always shield, block water gasket for packing and wrapped water blocking layer, steel-tape armouring layer and contain the sheath of alkyl copper, cable high-low temperature resistant, good insulation preformance, puncture voltage height, heat-resistance index are big, flame-retardant, shield effectiveness are good, low electric capacity, low inductance have the performance of protection against rodents, termite-proof, fire prevention, explosion-proof, waterproof.Can be widely used in signal transmission, the detecting instrument of field automation control systems such as metallurgy, the energy, electric power, weaving, chemical industry, medicine, food, the connection of instrument, the excellent popularization using value is arranged.
