Abstract
Disclosed in the utility model is a high temperature-resistance fireproof control cable comprising a ceramic silicone rubber outer sheath, a copper braiding and shielding layer, a main power wire core and shielded wire cores. The main power wire core is formed by extruding three silver-plated copper core stranded conductors by a tetrafluoroethylene-hexafluoropropylene copolymer insulating layer. The shielded wire cores are formed by extruding aluminium alloy conductors by silicone rubber insulating layers; and one main power wire core is extruded by the four shielded wire cores tightly. The four shielded wire cores are extruded by the copper braiding and shielding layer to form a cable core; a ceramic fireproof filling layer is arranged in the gap in the cable core; and the ceramic silicone rubber outer sheath extrudes the copper braiding and shielding layer. With the provided cable, cable laying of the high-voltage power line and power line can be realized. The cable has characteristics of high temperature resistance, fire resistance, light weight, excellent electric performance, excellent anti-interference performance, and high structural strength.
Description
Technical field
The utility model relates to field of cables, relates in particular to a kind of fire resistant control cables.
Background technology
At present, phase conductor, overhead ground wire and the power cable of optical cable and power transmission line are complex as a whole to structure, be optical cable, this structure has ground wire and the dual-use function of communicating by letter concurrently, and power department is the security reliability that improves optical cable transmission circuit, preferably electric power special optical cable is laid along high-voltage line power line, but common cable can not be tackled hot weather, can not prevent fires, and tensile strength is low, a little less than antijamming capability, the electric power that can not bear under high-pressure situations is carried.Therefore, need to provide a kind of new technical scheme to solve the problems referred to above.
Utility model content
In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide a kind of fire resistant control cables.
The utility model takes following technical scheme to realize: a kind of fire resistant control cables, it is made up of ceramic silicon rubber oversheath, copper core woven shield, active force core and shielding core, and described active force core is to extrude three silver-plated copper core stranded conductors by perfluoroethylene-propylene insulating barrier to form; Described insulated wire cores is to extrude aluminium alloy conductor by silicone rubber insulation layer to form; Four shielding conductor heart yearn cores closely extrude an active force core; It is cable core that described copper core woven shield extrudes four shielding cores; In gap in described cable core, be provided with pottery fire prevention packed layer; Described ceramic silicon rubber oversheath is extruded on copper core woven shield.
The utlity model has in sum following beneficial effect: this cable is applicable to high-voltage line power line cable laying, there is high temperature resistant, fire prevention, lightweight, superior electrical property, interference free performance excellent, and the high feature of structural strength.
