Summary of the invention
For the deficiencies in the prior art, the object of this invention is to provide a kind of manufacture method of core rod of insulator, can produce the plug with wire rod, plug production efficiency is higher, reduces costs.
For achieving the above object, the technology used in the present invention means are as follows: a kind of insulator core rod manufacturing method, comprises the following steps: one, be arranged in insulating cylinder by the hollow pipe being used for placing wire rod; Two, hollow pipe in this insulating cylinder is filled filler outward, form wire rod core rod unit; If three using a wire rod core rod unit as core rod of insulator, then directly carry out the 5th step; If by this some wire rod plug unit combination, maybe this wire rod core rod unit and inner core rod are combined, then this step proceeds the 4th step after completing; Four, the wire rod core rod unit combined or the wire rod core rod unit combined and inner core rod stationary pipes are fixed; Five, wire rod is put into by above-mentioned hollow pipe.
Preferably, also one of step 4 is comprised between above-mentioned steps four and step 5: by the gap-fill filler in stationary pipes.This filler can be the binding agent with cementation, can be megohmite insulant with insulating effect etc.More preferably, this filler is epoxide-resin glue, and between this step 4 and step 5, one of step 4 is rear also comprises step 4 two: be cured by this filler.Mechanical strength and the insulation property of this core rod of insulator can be improved like this.
Preferably, also step 6 is comprised after above-mentioned steps five: fill fixture by above-mentioned hollow pipe.
Preferably, above-mentioned wire rod is optical fiber, and this core rod of insulator is for the manufacture of optical fiber composite insulator.
Preferably, the shape of above-mentioned wire rod core rod unit or inner core rod cross section is the polygon such as circle or triangle, quadrangle, pentagon.Those skilled in the art thinkable shape of other one's own professions is also in disclosed scope.
Preferably, the filler in above-mentioned steps two is polyurethane foam.What this filler played act as the position fixing this hollow pipe, and can prevent extraneous steam from entering, so that affects insulation property.
Preferably, above-mentioned insulating cylinder, hollow pipe, stationary pipes and inner core rod can be glass material, ceramic material, glass steel material etc.
Preferably, the stationary pipes in above-mentioned steps four is the winding layer that glass fiber yarn is wound.Insulator core bar structure can be made more stable, and mechanical performance is better.
Preferably, above-mentioned fixture is epoxide-resin glue.The arbitrarily movement in hollow pipe of this wire rod can be prevented.
Above-mentioned insulator core rod manufacturing method, compared with the common core rod of insulator production method with wire rod, the installation of wire rod is more convenient, and production efficiency is high, provides cost savings.
