Abstract
The utility model discloses a kind of power transmission cable, comprise cable core, core conductor, outer jacket.Described cable core comprises two transmission heart yearns and a power supply heart yearn, power supply heart yearn outer cladding wheat drawstring, for reducing the broken skin risk of wire rod in processing and use procedure.Steel core, insulating barrier, damp-proof layer, steel ball protective layer, outer jacket is comprised in protective layer of the present utility model.Described transmission heart yearn and power supply heart yearn both sides are provided with the core conductor that three are provided with insulating barrier, are provided with a steel core in the middle of cable, steel core be divided into three mutual stranded in cable centerline position.This cable is provided with steel ball protective layer in the middle of insulating barrier and outer jacket, can strengthen the bulk strength of cable, make cable can bear larger load and External Force Acting.Due to the setting of this coat of metal, serve the effect of protection insulating barrier, for cable provides better guarantee, the not only stable performance of the utility model cable, and also structure is simple, is convenient to produce.
Description
Technical field
The utility model relates to a kind of power transmitting device field, particularly relates to a kind of power transmission cable.
Background technology
At present along with socioeconomic development, the routine work of people, life, productive power amount increase day by day, therefore also increasing for cable use amount, but some cable is in wet environment for a long time, cable is except must possessing resistant to mechanical damage function in a humidity environment, also should possess good moisture barrier properties.Existing cable cover(ing) is owing to lacking good permeability resistance, water is easy to penetrate into cable inside, insulating barrier is damaged, affect the useful life of cable, can cause cable cisco unity malfunction time serious, common cable strength is less, easily ruptures when bearing larger load or external force, affect the normal use of cable, the resistance to compression resistance to tension of cable is also poor.
Utility model content
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, provides a kind of cable, have protection against the tide, function, thus ensure its useful life.
The technical solution of the utility model is: a kind of power transmission cable, comprises steel core, insulating barrier, steel ball overcoat, damp-proof layer, outer jacket.Described transmission heart yearn and power supply heart yearn both sides are provided with the core conductor that three are provided with insulating barrier; described two transmission heart yearn symmetries are positioned at below power supply heart yearn; a steel core is provided with in the middle of cable; steel core is divided into three; article three, steel core stranded centre of transmitting heart yearns and a power supply heart yearn space in two mutually; side is provided with the core conductor that three are provided with insulating barrier, and this cable is also provided with steel ball protective layer and damp-proof layer in the middle of insulating barrier and outer jacket.
Further, described power supply heart yearn is coated with two-sided wheat drawstring.
Further, the material of described coat of metal is copper facing steel band.
Further, described steel core is entwined by three flat copper cladding stranded wires are mutually stranded.
Further, described thickness of insulating layer is less than steel ball protective layer, and the thickness of described steel ball protective layer is less than outer jacket, described in
Damp-proof layer thickness is identical with thickness of insulating layer.
Further, the material of described outer jacket is polyethylene.
Further, the material of described damp-proof layer is polyurethane or polyvinyl chloride.
Further, the material of described wheat drawstring is aluminum foil mylar belt or heat-sealing mylar.
The beneficial effects of the utility model are: in cable core, steel core is that three flat copper cladding stranded wires are entwined by stranded mode, steel core mainly serves the effect increasing cable internal intensity, the material of outer jacket is polyethylene, polyethylene has good physically encapsulation and good resistance to wear, anti-pressure ability is strong and be less likely to occur to rupture thus affect the normal use of cable, damp-proof layer to a certain extent can moistureproof and waterproof, the material of damp-proof layer is polyvinyl chloride or polyurethane, polyvinyl chloride and polyurethane have good water proofing property, polyamide also has excellent electrical insulation capability, volume resistance is very high, can breakdown voltage resistant height, it is excellent insulating material, can prevent cable from making moist into problems such as water, power supply heart yearn outer cladding wheat drawstring, the material of wheat drawstring can be aluminum foil mylar belt or heat-sealing mylar, therefore can design thinner of the core insulation of power supply heart yearn but broken skin risk can not be there is, improve the fail safe in use of power supply heart yearn, reduce the overall dimensions of cable simultaneously.
