Abstract
Discloses is a composite rigid suspension insulator for a subway. The insulator has an integral structure, and is composed of a treaded rod at the upper part, stainless-steel steel cap flanges below the threaded rod, an epoxy resin solid rod at the middle part, silicone rubber umbrella shirts and a screw hole at the lower part; the stainless-steel steel cap flanges are cylindrical, hollow and semi-through, and sleeve two ends of the epoxy resin solid rod; and the three silicone rubber umbrella shirts which are uniformly arranged wrap the outside of the epoxy resin solid rod, and the epoxy resin solid rod has cylindrical appearance. The umbrella shirts employ open type big umbrellas; the composite rigid suspension insulator has the advantages of good mechanical strength, good hydrophobicity, good electrical performance, good anti-pollution performance, high withstand voltage, good dust prevention, convenient installation, high stability and compact structure; and the composite rigid suspension insulator can be widely applied to subway and light rail lines.
Description
Technical field
The utility model relates to compound electrical materials and appliances field, specifically compound rigid suspended insulator for a kind of subway.
Background technology
At present, subway mostly adopts ceramic insulator with insulator, ceramic insulator processing technology complexity, and the course of processing is very difficult to control, and quality is also difficult to hold, and mechanical strength is low, easily fracture, electric property is also unstable.
Utility model content
The deficiency existing for above-mentioned prior art, the purpose of this utility model is to provide compound rigid suspended insulator for a kind of high performance subway, and it is also applicable to light rail.
The technical solution of the utility model is: compound rigid suspended insulator for a kind of subway, described insulator is an entirety, it is made up of the screwed hole of the stainless steel steel cap flange below screw rod, the screw rod on top, middle epoxy resin solid bar, silicon rubber full skirt, bottom, described stainless steel steel cap flange is cylindrical and hollow half-pass, and stainless steel steel cap flange is enclosed within the two ends of epoxy resin solid bar; The outer wrap of described epoxy resin solid bar has 3 evenly distributed silicon rubber full skirts, and the profile of epoxy resin solid bar is cylindrical.
Described insulator is high, and for 165mm, diameter are 180mm, the screw diameter on top is 16mm, and the screwed hole internal diameter of bottom is 16mm.
The utility model has the advantages that: the utlity model has good mechanical strength, hydrophobicity and electric property, full skirt adopts open gamp, and anti-pollution characteristic is good, withstand voltage height, prevents dust, easy for installation, stability is strong, of a tightly knit structure, can be widely used in subway, light railways.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Now by reference to the accompanying drawings, the utility model is further described.
As shown in Figure 1, compound rigid suspended insulator for subway, described insulator is an entirety, it is made up of the screwed hole 5 of stainless steel steel cap flange 2 below of the screw rod 1 on top, screw rod 1, middle epoxy resin solid bar 3, silicon rubber full skirt 4, bottom, described stainless steel steel cap flange 2 is cylindrical and hollow half-pass, and stainless steel steel cap flange 2 is enclosed within the two ends of epoxy resin solid bar 3; The outer wrap of described epoxy resin solid bar 3 has 3 evenly distributed silicon rubber full skirts 4, and the profile of epoxy resin solid bar 3 is cylindrical.Insulator is high, and for 165mm, diameter are 180mm, screw rod 1 diameter on top is 16mm, and screwed hole 5 internal diameters of bottom are 16mm.
The rigid suspended insulator of such subway, has good mechanical strength, hydrophobicity and good electric property, and full skirt adopts open gamp, and anti-pollution characteristic is good, and gradation for surface pollution is high, and withstand voltage height, prevents dust, and can be widely used in subway, light railways.
