Abstract
The utility model discloses a parallel overhead wire harness, which comprises a plurality of conductors, wherein the plurality of conductors are arranged at one same plane and are arranged parallel to each other; an insulating layer is externally formed on each conductor by extrusion molding; and the insulating layers outside two adjacent conductors are connected integrally through connecting ribs. With the adoption of the parallel overhead wire harness, the problems that an existing overhead insulated wire is large in investment, likely to be stolen, large in maintenance expense, large in erection workload, high in erection cost and unattractive are solved; the insulating layer is beneficial for erection and small in occupied space, and has few hardware fittings and erection tower poles, so that the parallel overhead wire harness is particularly applicable for areas with dense population, forest regions and the like.
Description
Technical field
The utility model relates to field of cables, specifically is a kind of parallel shelf ceases to be busy bundle.
Background technology
The appearance of aerial insulated wire has solved a series of shortcomings of built on stilts plain conductor, has obtained the approval in market.But single insulated wire takes up room when setting up greatly, and cost is high, is prone to theft, and maintenance cost is big, and workload is big when laying, and sets up with gold utensil manyly, and it is high and not attractive in appearance to set up cost.
The utility model content
The purpose of the utility model provides a kind of parallel shelf ceases to be busy bundle, solve existing aerial insulated wire high investment, be prone to theft, maintenance cost is big, when laying workload big, set up the high and inaesthetic problem of cost.
The technical scheme of the utility model is following:
A kind of parallel shelf ceases to be busy bundle; Include many conductors; It is characterized in that: described many conductors are positioned on the same plane and are arranged parallel to each other, and every conductor has insulating barrier through extrusion moulding respectively outward, connect as one through dowel between the insulating barrier outside adjacent two conductors.
Described parallel shelf ceases to be busy bundle is characterized in that: described many conductors are circle and press copper core or aluminium core.
The beneficial effect of the utility model:
The utility model has solved existing aerial insulated wire high investment, has been prone to theft, maintenance cost is big, when laying workload big, set up the high and inaesthetic problem of cost; Insulating barrier is beneficial to and lays and take up room little; The gold utensil annex is few; It is few to set up the tower bar, is particularly useful for densely populated and zone such as forest zone.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Referring to Fig. 1; A kind of parallel shelf ceases to be busy bundle includes 1, four conductor 1 of four conductors and is positioned on the same plane and is arranged parallel to each other; Every conductor has insulating barrier 2 through extrusion moulding respectively outward, connects as one through dowel 3 between the insulating barrier outside adjacent two conductors.
In the utility model, four conductors 1 are circle and press copper core or aluminium core.
The manufacture craft of the utility model is following:
According to GB14049, the design of GB12527 regulation and making, according to the conductor of standard application certain specification, and the radical of definite single line.To be drawn into required specification to copper (aluminium) line according to above-mentioned.The conductor resistance that draws should meet the requirements, and accurate dimensions arranged, any surface finish.Concrete condition according to conductor is selected suitable thread reaming machine; The traction rotating speed and the strand cage rotating speed with turn to all up to specification; Twisted wire is wanted strict control twisted wire quality, and the twisted wire pitch will meet the regulation of operation card, also will select the suitable mould that presses for use according to pressing coefficient.Insulating barrier adopts the weather resistant polychloroethylene insulation material.With the parallel placement of conductor, extrusion method is extruded with common cable during extrusion molding, and mould adopts porous core extrusion die, and many conductors are extruded simultaneously when extruding, and is connected and have between the insulating barrier of each conductor with dowel that insulating barrier is extruded simultaneously.The speed of unwrapping wire is wanted steadily, and the tension force of core is wanted evenly.The speed of the screw speed of plastic extruding machine, the working temperature of various piece, traction and the speed of take-up will meet the regulation of technology.Each parts are wanted co-ordination.Problem such as stop surface of insulating layer and bubble, flake, fold arranged, be a bit darkish in color.
Claims (2)
1. parallel shelf ceases to be busy bundle; Include many conductors; It is characterized in that: described many conductors are positioned on the same plane and are arranged parallel to each other, and every conductor has insulating barrier through extrusion moulding respectively outward, connect as one through dowel between the insulating barrier outside adjacent two conductors.
2. parallel shelf ceases to be busy bundle according to claim 1 is characterized in that: described many conductors are circle and press copper core or aluminium core.
