In hollow combined insulator silicon rubber umbrella manufacturing process, epoxy resin fiberglass pipe (hereinafter referred to as glass
Pipe) silicon rubber of outer wall vulcanizes under 150 DEG C of high temperature and 15MP pressure, and fiberglass tubes cannot bear such huge pressure at high temperature
Power, therefore a steel liner tube must be lining into fiberglass tubes, otherwise fiberglass tubes are inherently by pressure break.
The bushing pipe used in fiberglass tubes when existing hollow combined insulator sulphurated siliastic umbrella cover is to be more than 10mm with wall thickness
Seamless steel pipe Precision Machining form, outer diameter is identical as glass bore, and carry identical taper, mutually coincide it is closely connected.Cause
This, it is adapted only to the winding fiberglass tubes for using identical size bushing pipe as winding pipe mold production.
The axis shape of the glass fibre and pipe that wind fiberglass tubes forms an angle, and successively cross winding forms certain thickness
Fiberglass tubes have preferable anti-atmospheric pressure performance, suitable for there is the casing composite insulator of high-voltage isulation gas in making.But

As processing method be burn or landfill, but burn generate toxic gas, landfill then centuries be difficult to degrade, destroy air, soil
And descendants is left a legacy of trouble at water source, this is wound around fiberglass tubes and produces the maximum sequelae left.
To solve the above-mentioned problems, this patent utility model people had once invented the major diameter pultrusion pipe (patent No.
ZL201320522551.5).Through the winding pipe Experimental Comparison with same diameter, wall thickness and length, pultrusion pipe is bent than winding pipe
Intensity is 3 times big.If one end is fixed, apply same flexure load in the other end, pultrusion pipe bending deformation quantity only has the 1/ of winding pipe
3.That is, if keeping the bending strength of post composite insulator and bending deformation quantity constant, the diameter or wall of fiberglass tubes
Thickness can reduce 1/3, greatly reduce production cost.In addition, pultrusion pipe can continuous pultrusion, discard end, pipe table without both ends
Face does not need turnery processing yet, and entire production process does not generate the waste material of pollution environment.
Compared with winding pipe, pultrusion pipe no doubt has many good qualities, but when pultrusion pipe is more than certain length, has slight curved
Song, although amount of bow is much smaller than standard GB/T/T25096-2010《Alternating voltage is compound absolutely with pillar higher than 1000V substations
Edge --- definition, test method and acceptance criterion》Specified value, but this flexural deformation makes bad insertion in pultrusion fiberglass tubes
The rigid liner coincideing with its inner wall.High pressure gas and liquid were once filled in fiberglass tubes by we, to offset fiberglass tubes vulcanization
The pressure born when silicon rubber, but find that two hang-ups cannot solve：1, gas or liquid pressing and release time in fiberglass tubes
Be difficult harmonious with rate and silicon rubber expanded by heating pressing time and rate outside fiberglass tubes, otherwise cause pultrusion fiberglass tubes by
External pressure pressure break or be pressed within power explosion；2, use liquid or gas as the filler between the steel liner tube and fiberglass tubes, it cannot
Pultrusion pipe alignment to bending.Therefore, bushing pipe a kind of while that there is two big function of alignment and pressure-bearing how is found, use has been become
Pultrusion pipe manufactures the biggest problem of composite insulator with hollow support.
