Abstract
The utility model relates to a composite insulating object with a multilayer structure, which is a hollow pipeline with the multilayer structure of alternating radial direction ring epoxy resin fiber layers and longitudinal direction epoxy resin fiber layers. In order to enhance the property of electricity resistance, a pipe core can be a hard polyamine ester foam filler. A high-strength epoxy resin multilayer pipe is used as an electrified working tool and has the favorable property of electricity resistance, and moreover, according to rain drying performance, voltage of 100KV is applied when the length of the pipe is one meter; rainfall from 60 to 90 mm can not flash in one hour; bending fatigue can repeat 4000 times when loaded 1100N; after bent, a wetting experiment is carried out 168 hours; leakage current does not exceed 50uA; a torsion experiment can not deform when reaching 40N; a residual angle is less than 1 DEG; a torsion experiment can not break when reaching 80N.
Description
The utility model belongs to a kind of composite insulating body with sandwich construction.
In known technology, domestic insulating bar commonly used is the epoxy resin fiber laminated tube, but the latter is owing to the restriction of prior art, and finished product is a kind of single layer structure that has air gap, thereby performances such as electric strength, the performance of drenching with rain, flexural fatigue and torsion test are all relatively poor.
The purpose of this utility model is to improve the configuration state of epoxy resin pipe, improves its electric strength and other serviceability.
Embodiment of the present utility model is to adopt the epoxy resin radial loop with multilayer alternating structure to constitute around fibrage and longitudinal fiber layer.On processing technology, adopt the formed by extrusion and tension of advanced technology, not only effectively got rid of the air gap in the finished product, guaranteed that also finished product has alternating multilayered structure and ladder network structure, as tools for live working and the use of other purposes the time, can be the hard polyurethane foam plastic filler at die.
The utility model has the advantages that: when this high strength epoxy resin multilayer pipe is used as tools for live working, has good electric durability energy, the performance of drenching with rain is that pipe range applies 100KV voltage for 1 meter, and 60～90mm, rainfall 1 hour be flashover not, flexural fatigue reaches loading 1100N 4000 times repeatedly, crooked back was by the test of making moist in 168 hours, and leakage current is no more than 50 μ A, and it is indeformable that torsion test reaches 40N, remaining angle＜1 °, 80N does not destroy.This high strength epoxy resin multilayer pipe can also be used in other industry as the high-quality pipeline except that using as tools for live working.
Accompanying drawing is the utility model example structure view.
The drawing label declaration is as follows:
1-longitudinal fiber layer, 2-radial loop be around fibrage, the 3-filler.
Embodiment:
Accompanying drawing is the utility model example structure view, and it is the hollow pipe that is made of around fibrage 2 and longitudinal fiber layer 1 multilayer epoxy resin alternating structure radial loop.Radial loop alternately can adopt 5～10 layers around fiber and longitudinal fiber layer, in order to strengthen its anti-electricity and mechanical performance, can be hard polyurethane foam plastics charges 3 at its die.
Claims (2)
1, a kind of high strength epoxy resin multilayer pipe is characterized in that: it is by the multilayer alternating structure, and radial loop constitutes around fibrage (2) and longitudinal fiber layer (1), and tube hub is hollow.
2, high strength epoxy resin multilayer pipe as claimed in claim 1 is characterized in that: described tube hub is charges (3).
