Description
Technical field:
The utility model relates to a kind of 10 and 35KV sulphurated siliastic insulation shielding metal tube bus bar terminal head, is used for 10 and the 35KV electric pressure metallic conduction pipe insulation bus in power transformation engineering field.
Background technology:
The terminal connection method of existing insulation shielding metal tube bus has two classes: a class is that the bus of epoxy resin or the insulation of epoxy resin impregnating varnish layer platen is in the process of manufacturing process, electric capacity ring indentation method is successively adopted in the end of bus, its shortcoming is that the elasticity of material is limited, easy be full of cracks in service, cause insulation breakdown, technology is comparatively complicated; The 2nd, the terminal that the polyethylene extrusion material is done the insulation shielding metal tube bus of insulating barrier adopts wrapped band method, and shortcoming is almost not adopt the stress evacuating measure of metallic shield end, the problem that puncture is arranged in service.
Summary of the invention:
The purpose of this utility model is to provide a kind of 10 and 35KV sulphurated siliastic insulation shielding metal tube bus bar terminal head, and it is simple in structure, and dependable performance is with low cost, and is easy for installation, is easy to grasp.
The technical solution of the utility model is achieved in that 10 and 35KV sulphurated siliastic insulation shielding metal tube bus bar terminal head, it is characterized in that: gold utensil is connected on the metal tube bus, the metal tube bus is with the sulphurated siliastic insulating barrier outward, insulating barrier is with outer shielding layer outward, be with metal screen layer on the outer shielding layer, metal screen layer is provided with pyrocondensation protecting pipe outer jacket, suit pyrocondensation stress tube on the pyrocondensation protecting pipe outer jacket, pyrocondensation outdoor insulative pipe is housed on the pyrocondensation stress tube, the single hole full skirt is shunk fixedly on the pyrocondensation outdoor insulative pipe, and the junction of gold utensil and pyrocondensation outdoor insulative pipe is fixed with silicon rubber self-adhesion insulating tape.
It is simple in structure for good effect of the present utility model, and dependable performance is with low cost, easy for installation, is easy to grasp; Adopt wide-aperture pyrocondensation pipe fitting corresponding with heavy in section metal tube bus, the terminal of making is aesthetic in appearance, is easy to bus and patrols and examines the location; Form the consistency of material with the pyrocondensation outer jacket of insulation shielding metal tube bus, can play insulation, anticorrosion and the moisture-proof role of silicon rubber insulation shielding bus.
Description of drawings:
Fig. 1 is a schematic cross-section of the present utility model
