Abstract
The utility model relates to a double core flat house lead in wire, which is composed of conductive wire cores (1), an insulation layer (2), and an intermediate connecting belt (3), wherein, the conductive wire cores (1) are two mutually parallel single or twisted conductive wire cores; the insulation layer (2) is made of materials such as weather resistant polyethylene, weather resistant polyvinyl chloride, flame resistant and weather resistant polyethylene, flame resistant, or weather resistant polyvinyl chloride. The intermediate connecting belt (3) is a flat belt which is used for connecting two insulated wire cores. Therefore, the utility model has the advantages of property of atmospheric corrosion resistance, long service life, and convenient installation. Besides, the requirements of current supply of lighting, power, and living conditions can be satisfied in all directions.
Description
The utility model belongs to the house lead in field of cables.
At present, the domestic house lead in of producing adopts rubber insulation, cotton yarn or glass braid always, is coated with cured electric wire, is used for each side illumination, power and living facilities.This rubber insulation house lead in has a lot of shortcomings, and in exposing to the weather, rubber house lead in that newly lays is through after 1～2 year, and outside cured layer comes off gradually, and cotton yarn or glass fibre begin fragmentation.Along with the increase of time, the rubber insulation layer begins to be clamminess and to chap.In addition, rubber also can cause the copper conductor blackout, and is sticking mutually with conductor, is difficult to peel off, and insulation phenomenons such as layering occur because of vertical bag reason.These defectives cause the rubber house lead in to use inconvenience, life-span to descend, and also can cause other accidents such as short circuit.
The purpose of this utility model provides the double core flat type house lead in of new insulating material of a kind of usefulness and advanced technologies production.
This double core flat type house lead in that the utility model provides, it is made up of conductor wire core, insulating barrier and middle linking belt.Introduce the utility model in detail below in conjunction with accompanying drawing
Fig. 1: schematic diagram of the present utility model
Fig. 2: schematic cross-section of the present utility model
Among the figure: 1 is conductor wire core, and 2 is insulating barrier, and 3 is middle linking belt.
The utility model is by two simple roots that are parallel to each other or twisting type conductor wire Core (1) and from the poly-second of weather-resistance polyethylene, weather-proof polyvinyl chloride, flame-proof weather-resisting A kind of material system of selecting in the material group that alkene, flame-proof weather-resisting polyvinyl chloride form One-tenth insulating barrier (2) reaches the middle linking belt (3) with insulating barrier (2) commaterial Form (seeing Fig. 1, Fig. 2). Conductor wire core (1) is outer to be surrounded by insulating barrier (2), two Linking belt (3) in the middle of being connected with between the root conductor wire core (1).
The utility model is owing to adopt new structure and insulating barrier uses new material, Solved the rubber house lead in and used the defectives such as inconvenience and life-span weak point, improved anti-big The gas ageing properties increases the service life, and current-carrying capacity also is improved simultaneously, for The service entrance cable field provides a kind of novel house lead in.
Claims (1)
1. double core flat type house lead in, by two simple root conductor wire cores [1] that are parallel to each other, also can adopt stranded formula conductor wire core [1], with a kind of material of selecting the material group of forming from weather-resistance polyethylene, weather-proof polyvinyl chloride, flame-proof weather-resisting polyethylene, flame-proof weather-resisting polyvinyl chloride make insulating barrier [2] and with middle linking belt [3] composition of insulating barrier [2] commaterial, it is characterized in that being surrounded by insulating barrier [2] outside the conductor wire core [1] linking belt [3] in the middle of between two conductor wire cores [1], being connected with.
