Abstract

The utility model discloses an instrument cable for a power generator. A conductor is formed by bundling of a plurality of tinned flexible copper wire; an insulating layer made of a polyvinyl chloride polymer material is extruded on the conductor so as to form an insulating wire core; a plurality of insulating wire cores are stranded to form a cable core; the cable core is wrapped by a PP tape so as to form an isolation layer; and an outer sheath layer is arranged outside the isolation layer which is formed by extrusion of the polyvinyl chloride polymer material. The instrument cable for the power generator is simple, reasonable and scientific in structure, convenient in manufacture, resistant to low temperature, great in flexibility, resistant to oil, resistant to abrasion, resistant to ozone aging, resistant to flame, resistant to acid and alkali, and excellent in electrical and mechanical properties.

Description

A kind of generator instrument cable

technical field

The utility model relates to a kind of instrument cable, relates in particular to a kind of generator instrument cable, belongs to technical field of electric wires and cables.

Background technology

Electric energy is one of topmost energy of modern society.Generator is the plant equipment that the energy conversion of other form is become to electric energy, it is driven by the hydraulic turbine, steam turbine, diesel engine or other dynamic power machine, by current, and air-flow, the Conversion of Energy that fuel combustion or nuclear fission produce is that mechanical energy is passed to generator, then is converted to electric energy by generator.Generator is in industrial and agricultural production, and national defence, has been widely used in science and technology and daily life, and this just requires generator electric wire to have good safety and reliability.

utility model content

The utility model provides a kind of low temperature resistant, soft, oil resistant, wear-resisting, resistance to ozone aging, difficult combustion, acid and alkali-resistance, has superior electric property and mechanical generator instrument cable simultaneously.

Scheme of the present utility model is as follows: a kind of generator instrument cable, comprise conductor, insulated wire cores, and conductor adopts many zinc-plated soft copper tow to close, and extrudes and adopt the insulating barrier of polyvinyl chloride polymerization body material to form insulated wire cores on described conductor; Three stranded rear wrapped polyurethane belting layers of insulated wire cores and silver-gilt copper wire sub-shield form core, four stranded rear wrapped polyurethane belting layer II of core, and the outer wrapped PP band of described ammoniacum belting layer II forms separator; Described separator also arranges galvanized steel strip armour, external sheath layer by the extrusion modling of polyvinyl chloride polymerization body material outward; Between four described cores, insulated wire cores II is also set, described insulated wire cores II is made up of the outer wrapped PP belting layer of conductor, and a tinned copper wire drainage thread is also set in described armour.

Further, described conductor structure and conductor DC resistance meet the requirement of the 5th kind of conductor in GB/T 3956, and it is 1.55 mm that described cross-sectional area of conductor amasss ²~ 2.5 mm ².

The utility model structural design is simple, scientific and reasonable, manufactures easily, and conductor is that many zinc-plated soft copper tow close, and can effectively prevent the aging catalytic action of copper conductor to insulating barrier, to ensure the useful life of insulating barrier.Meanwhile, also can effectively prevent the oxidation of soft copper monofilament conductor itself at the electroplating surfaces with tin of soft copper monofilament, increase the safety and reliability in use procedure.The utility model cable insulation adopts cold resistance polyvinyl chloride polymer material to extrude moulding, has effectively improved the serviceability of product.That cable has is low temperature resistant, soft, oil resistant, wear-resisting, resistance to ozone aging, difficult combustion, acid and alkali-resistance, and electric property and mechanical performance are good simultaneously, particularly have can use continuously at low temperatures with temperature environment jumpy in still retention is stable.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described further.

A kind of generator instrument cable, comprises conductor, insulated wire cores, and conductor adopts many zinc-plated soft copper tow to close, and extrudes and adopt the insulating barrier 2 of polyvinyl chloride polymerization body material to form insulated wire cores on described conductor 1; Three stranded rear wrapped polyurethane belting layers 3 of insulated wire cores and silver-gilt copper wire sub-shield 4 form core, four stranded rear wrapped polyurethane belting layer II 5 of core, and the outer wrapped PP band of described ammoniacum belting layer II 5 forms separator 6; Described separator also arranges galvanized steel strip armour 7, external sheath layer 8 by the extrusion modling of polyvinyl chloride polymerization body material outward; Between four described cores, insulated wire cores II 9 is also set, described insulated wire cores II is made up of the outer wrapped PP belting layer of conductor, and a tinned copper wire drainage thread 10 is also set in described armour 7.

Described conductor structure and conductor DC resistance meet the requirement of the 5th kind of conductor in GB/T 3956, and it is 1.55 mm that described cross-sectional area of conductor amasss ²~ 2.5 mm ².

Although above embodiment of the present utility model has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned execution mode according to conception of the present utility model and change and amendment; when its function producing does not exceed spiritual that specification and accompanying drawing contain yet, all should be within protection range of the present utility model.
