Abstract
The utility model discloses a control cable of silicone rubber insulation and heat resistance, comprising a plurality of conductors. The conductors are formed by stranded tinned copper wires; a stranded pitch diameter ratio of the conductors is 13-21; filament fracture elongation is not less than 16%; extruded insulating layers are arranged at exteriors of the conductors; taped coverings formed by a waterproof belt and a non-woven fabrics double layer taping are taped on external sides of the insulating layers of the conductors; the taped coverings are successively wrapped by shielding layers and sheath layers; skeletons are arranged in the sheath layers; and the skeletons are structures with webbed cross sections braided by polygon steel wires. According to the utility model, taped coverings formed by a waterproof belt and a non-woven fabrics double layer taping are taped on external sides of the insulating layers of the conductors, so that waterproof performance of a cable reaches the standard under a special circumstance of mobile heat and corrosion prevention; the skeletons are arranged in the sheath layers of a cable, so that extrusion prevention ability of a cable is enhanced; and the soft characteristics such as relatively good heat stability, high temperature resistance, radiation resistance, extreme coldness resistance, corrosion resistance, and excellent insulating performance are possessed.
Description
Technical field:
The utility model relates to the control cable field, relates in particular to the heat-resisting control cable of a kind of silicon rubber insulation.
Background technology:
China's economic growth continuously and healthily; For cable products provides the huge market space, the temptation that Chinese market is strong makes the world all focus on Chinese market to sight; Reforming and opening up to the outside world short decades, the formed huge production capacity of Chinese cable manufacturing industry lets the world regard with special esteem.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.
Control cable is mainly used in the cable that transmits control, measuring-signal etc., and general control cable is in industrial and mining enterprises, energy traffic department, is applicable to ac rated voltage 450/750v and followingly moves or fixedly lay the electrical appliance instrument leads or signal transmits.
For heat-resisting control cable under mobile heatproof corrosion-resistant special occasions; The water resistance of cable is relatively poor; Can not satisfy the demand of work under the actual environment; The utility model has effectively solved above-mentioned problem at the insulating barrier wrapped water blocking tape in the outside of several conductors and the lapping layer of the double-deck wrapped formation of nonwoven fabrics.
The utility model content:
The purpose of the utility model provides the heat-resisting control cable of a kind of silicon rubber insulation, is widely used in industries such as metallurgy, thermoelectricity, electric power, petrochemical industry, factories and miness, has the anticorrosion specific (special) requirements occasion that waits of mobile heatproof and uses, and the construction of cable is simple, water resistance is good.
The technical scheme of the utility model is following:
The heat-resisting control cable of silicon rubber insulation comprises several conductors, it is characterized in that: several conductors all adopt the stranded formation of tinned copper wire; The stranded lay ratio of several conductors is 13-21; The single wire fracture percentage elongation is not less than 16%, the outer insulating barrier that is extruded with of several conductors, and the insulating barrier outside of several conductors is surrounded with the lapping layer of water blocking tape and the double-deck wrapped formation of nonwoven fabrics; Water blocking tape is positioned at the inboard; Lapping layer is enclosed with screen, restrictive coating outward successively, is provided with skeleton in the restrictive coating, and skeleton is that the cross section is the webbed structure of polygonal braided steel wire.
The heat-resisting control cable of described silicon rubber insulation is characterized in that: it is silicon rubber that described insulating barrier, restrictive coating adopt material.
The heat-resisting control cable of described silicon rubber insulation is characterized in that: the minimum bending radius of described cable permission is not less than 6 times of the outside diameter of cable.
The utility model has the advantages that:
The utility model is at the insulating barrier wrapped water blocking tape in the outside of several conductors and the lapping layer of the double-deck wrapped formation of nonwoven fabrics; Make that cable water resistance under mobile heatproof corrosion-resistant special occasions is up to standard; Be provided with skeleton in the restrictive coating of cable simultaneously; Strengthen the anti-extrusion ability of cable, had preferably flexible nature such as thermal stability, high temperature resistant, radiation hardness, anti-high and cold, corrosion-resistant, excellent insulation performance in addition.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
The heat-resisting control cable of silicon rubber insulation comprises several conductors 1, and several conductors 1 all adopt the stranded formation of tinned copper wire; The stranded lay ratio of several conductors 1 is 13-21, and the single wire fracture percentage elongation is not less than 16%, the outer insulating barrier 2 that is extruded with of several conductors 1; Insulating barrier 2 outsides of several conductors 1 are surrounded with the lapping layer 3 of water blocking tape 3-1 and the double-deck wrapped formation of nonwoven fabrics 3-2, and water blocking tape 3-1 is positioned at the inboard, has effectively strengthened the humidity resistance of cable; Lapping layer 3 outer screen 4, the restrictive coatings 5 of being enclosed with successively; Be provided with skeleton 6 in the restrictive coating 5, skeleton 6 has strengthened the anti-extrusion ability of cable for the cross section is the webbed structure of polygonal braided steel wire; It is silicon rubber that insulating barrier 2, restrictive coating 5 adopt material, and the minimum bending radius of cable permission is not less than 6 times of the outside diameter of cable.
