Abstract
The utility model discloses an environmental-friendly high temperature-resistant flame-retardant and fireproof macromolecule rubber insulation compensation conducting wire for thermocouples. The compensation conducting wire comprises a plurality of conductors, wherein insulation layers are arranged outside the conductors; a cabling and cable core wrap is arranged outside the insulation layers; a cable core and the cable core wrap are provided with a shielding layer; and sheath layer is arranged outside the shielding layer. The compensation conducting wire is simple in structure and convenient to manufacture; and cables can be frequently moved in the high temperature-resistant, flame-retardant, fireproof and severe environment in a larger range, so that the formula of a cable material is effectively changed, the problem of excessive defects of the conventional flame-resistant cables in the using process is solved, and the using range of the flame-resistant cables is obviously increased.
Description
Technical field
The utility model relates to the fire-retardant and fire prevention thermocouple of environment-friendly type thermostable and use the compensating wire field, and specifically being that a kind of environment-friendly type thermostable is fire-retardant and fire prevention polymer rubber insulation is mobile uses compensating wire with thermocouple.
Background technology
Along with society constantly advances, the user requires also increasingly high to cable performance, particularly to heat-resistant fireproof and fireproof cable field, seem more outstanding.Conventional fireproof cable is that conductor increases fire-resistant isinglass belt structure or magnesia outward, but these conventional fireproof cables all have a fatal defective: the cable high-temperature resistant result is relatively poor, and contaminated environment in the combustion process.Silicone rubber for cable itself also has certain fire protecting performance, and the silicon dioxide that cable generates in combustion process also can play insulating effect, but the flame retardant effect of silicone rubber for cable is relatively poor, and when cable fire, withdrawing the naked light cable will burn away, and can not extinguish automatically.The utility model patent is the fire-resistance property that has utilized silicon rubber intrinsic; Increased the molecular weight of silicon rubber; Also added simultaneously a certain amount of environment friendly flame retardant; Make it to become the fire-retardant and fire prevention of environment-friendly type thermostable worthy of the name and move and use flexible cable, increased a new kind in the fire-resisting cable, the while has also enlarged the scope of application of fire-resisting cable.
The utility model content
In order to overcome above-mentioned defective; The utility model provides the fire-retardant and fire prevention polymer rubber insulation thermocouple of a kind of environment-friendly type thermostable to use compensating wire; The frequent cable that moves in high temperature resistant, fire-retardant, fire prevention and the adverse circumstances can be arranged in a big way; Because changed the prescription of cable material effectively, solved the too many deficiency that conventional fire-resisting cable in use occurs, the scope of application of fire-resisting cable is obviously increased.
The utility model for the technical scheme that solves its technical problem and adopt is: the utility model relates to the fire-retardant and fire prevention polymer rubber insulation thermocouple of a kind of environment-friendly type thermostable and uses compensating wire; Comprise many conductors; Be provided with insulating barrier in the conductor outside; Be provided with stranding and core wrap in the insulating barrier outside, be provided with screen, outside screen, be provided with restrictive coating at cable core and core wrap.
As the further improvement of the utility model, said conductor material adopts and the identical alloy of the identical or nominal chemical analysis of the thermo wires of thermocouple, and the cross section is generally 1.0～2.5m ㎡.
As the further improvement of the utility model, said stranding and core wrap cable stranding outermost layer direction of lay are dextrad, and insulated wire cores should twist together.
As the further improvement of the utility model, said screen adopts the copper free wire braid shielded, and shielding density is not less than 80%.
The beneficial effect of the utility model is: the utility model is simple in structure; Easy to make; The frequent cable that moves in high temperature resistant, fire-retardant, fire prevention and the adverse circumstances can be arranged in a big way; Because changed the prescription of cable material effectively, solved the too many deficiency that conventional fire-resisting cable in use occurs, the scope of application of fire-resisting cable is obviously increased.
