Abstract
The utility model discloses a tensile cable for high temperature prevention, which comprises a plurality of conductors. Each conductor is formed by stranding tinned copper wire. The breaking elongation of a single wire is no less than 18%. An insulation layer is respectively extruded outside each conductor. The conductors coated with the insulation layers are mutually extruded to form a cable core. A wrapping layer is wrapped outside the cable core. The wrapping layer is formed by overlap wrapping of polyester tape. A filling layer which is filled with high temperature glass fiber is arranged between the wrapping layer and the cable core. A water resistant layer, a shielding layer and an inner sheath layer are sequentially coated outside the wrapping layer. A plurality of tensile ropes are arranged inside the inner sheath layer. An outer sheath layer is arranged outside the inner sheath layer. Cooling holes are circularly provided inside the outer sheath layer. According to the tensile cable for high temperature prevention, by adopting the high temperature resistant filling layer, the wrapping layer and the cooling holes inside the outer sheath layer, the cable is good in thermal stability; and simultaneously, the waterproof performance and the tensile strength of the cable can be improved and the service life of the cable is prolonged.
Description
Technical field:
The utility model relates to the control cable field, relates in particular to the anti-high temperature of a kind of tensile type and uses cable.
Background technology:
Continuous expansion along with industry sizes such as China Power industry, data communication industry, urban track traffic industry, car industry and shipbuildings; Demand to electric wire also will increase rapidly; Following electric wire already also has huge development potentiality, the control cable application suitable extensively.
Cable is when electric energy transmitting, because of conductor heating causes temperature rise, even continuous rising that can Yin Wendu and cause the hidden danger of burning.At present general cable is because of receiving the restriction of macromolecular material temperature resistant grade, and the cable surface heat radiation is slower, and the cable surface heat can't in time leave, thereby restriction and limit the ability of cable transmission electric energy has limited the ampacity of cable.
Therefore, how to improve the resistance to elevated temperatures of cable in the actual environment use, it is anti-that to pull performance be current problem demanding prompt solution.
The utility model content:
The purpose of the utility model provides the anti-high temperature of a kind of tensile type and use cable, is mainly used in tension in the laid processes and drags and require height, field of employment that heat resistance is good.
The technical scheme of the utility model is following:
The anti-high temperature of tensile type is used cable, comprises several conductors, and it is characterized in that: described several conductors all adopt the stranded formation of tinned copper wire; The single wire fracture percentage elongation is not less than 18%, the outer insulating barrier that is extruded with respectively of described several conductors, the mutual stranded formation cable core of several conductors of wrap insulate layer; Cable core is surrounded with lapping layer outward successively, and lapping layer adopts the overlapping wrapped formation of polyester belt, is provided with the high temp glass silk between lapping layer and the cable core and fills the packed layer that constitutes; Lapping layer is enclosed with water blocking layer, screen, inner restrictive coating outward successively; Be provided with several tension ropes in the inner restrictive coating, inner restrictive coating is provided with external sheath layer outward, along annular spread louvre is arranged in the external sheath layer.
The anti-high temperature of described tensile type is used cable, it is characterized in that: it is the high temperature fluoroplastics that described insulating barrier, inner restrictive coating, external sheath layer adopt material.
The anti-high temperature of described tensile type is used cable, and it is characterized in that: described water blocking layer adopts the overlapping wrapped formation of waterstop, and the rate of putting up is not less than 42%.
Compare with traditional high temperature-resistant cable, the superior part of the utility model is:
The utility model adopts the louvre of resistant to elevated temperatures packed layer, lapping layer and external sheath layer, makes cable have thermal stability preferably, and water resistance, tensile strength also are improved simultaneously, have prolonged the useful life of cable.
