Abstract
The utility model discloses an environmental-protection power cable, belonging to the technical field of a cable. The cable is formed by using XLPE as an insulating layer on the outer surface of a conductor, using an inorganic paper string an interphase stuffing, then lapping by using an LSOH (low smoke zero halogen) belt, and finally using an LSOH material as a jacket. The environmental-protection power cable has reasonable and simple structure, easy production and manufacturing and low cost, has the advantages of good electrical property, good electrical conductivity, good energy saving and environmental protection, good flame retardation and fire resistance and the like, can be widely applied in an electric power circuit distribution system with the flame retardant and fire resisting requirements in the fields of electric power, petroleum, petrochemistry, steel, building and the like and has better promotion valve and application value and wide market prospect.
Description
Technical field
The utility model relates to a kind of cable, specifically is a kind of frequency-changing cable, belongs to the cable technology field.
Background technology
Now, China's power industry has obtained fast development, as the leading products of electric power conveying---and the demand of power cable also increases day by day.Existing power cable (low pressure), mainly by comprising insulated wire cores, the lapping layer that the outside of insulated wire cores sets gradually, inner cushion layer, armour, external sheath layer, at three void fillers that thoroughly do away with between edge core and the lapping layer is polyester rope, oversheath is a polyvinyl chloride, not environmental protection, fire-retardant, fire resistance is poor, but also influence the transmittability of cable and rated current with the loss in the uiform section conductor.Therefore, adopt suitable flame-retardant environment-friendly materials in the cable production process, not only help protecting environment, reduce the circuit loss, also improved the flame-retardant performance of cable.
The utility model content
The purpose of this utility model is exactly the deficiency that exists at the existing power cable, provides a kind of fire-retardant, fire-resistant, good electrical property, heat-resistance index is big, thermal conductivity is good, energy-conservation, free of contamination environment-friendly type power cable.
A kind of environment-friendly type power cable described in the utility model, it is included in the insulated wire cores of the outer extruded insulation layer of conductor, and the outside of three phase isolated core sets gradually lapping layer and restrictive coating, in the space between three phase isolated core and the lapping layer filler is arranged.
Described filler is inorganic paper string filler, and insulating barrier is a crosslinked polyethylene extruded insulation layer, and lapping layer is a low smoke and zero halogen band lapping layer.Restrictive coating extrudes layer for the low smoke and zero halogen band.
The utility model is rational in infrastructure simple, and the manufacturing is easy, cost is low.Cable has conductor and allows working temperature height, advantages such as electrical property is good, transmission capacity is big, environmental protection and energy saving, structure is light, maintenance is simple, can satisfy the performance requirement of power cable environmental protection, flame-retardant fully, can be widely used in fields such as electric power, oil, petrochemical industry, iron and steel, building has the power circuit distributing system of flame-retardant requirement, has application value and vast market prospect preferably.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
1 conductor among the figure, 2 insulating barriers, 3 fillers, 4 lapping layers, 5 oversheaths.
Embodiment
As shown in Figure 1, environment-friendly type power cable described in the utility model, be that outer surface at copper conductor 1 extrudes crosslinked polyethylene (XLPE) and forms insulating barrier 2, thoroughly do away with edge core stranding by three, between the three phase isolated core, fill inorganic paper string as filler 3, wrapped with the low smoke and zero halogen band as lapping layer 4, on lapping layer 4, extrude the low smoke and zero halogen material and make restrictive coating 5.
