Abstract
The utility model discloses a plastic composite insulator which is composed of an inner core rod, an umbrella skirt outer protecting sleeve and a metal accessory. The utility model is characterized in that both ends of the inner core rod are conical shapes, and the inner core rod is sheathed and locked on the metal accessory by a counter-opening lock; so the tensile strength is increased. The umbrella skirt outer protecting sleeve is assembled on the inner core rod by using the polythene and by adopting the method of injection molding, so the creepage distance is increased, and the anti-corrosion ability and the anti-cracking ability of the insulator are realized. The utility model has the advantages that the life time is more than 20 years, the price is cheap, and the processing is convenient.
Description
The utility model relates to a kind of insulator that is used on the high-tension line.
" synthetic insulator " that the domestic market produces is made up of epoxy inner core, silastic material and metal-ware, be connected with the iron wedge between inner core and metal-ware and reinforce, this method connects, and have opening error and iron wedge depth of drive to influence mechanical performance, and inside and outside core is in conjunction with bad, easily gas leakage, soak tide, influence insulation property, the end easily produces corrosion phenomenon, and silicone rubber mechanical performance is poor, easily tears.
The purpose of this utility model is to provide a kind of plastics composite insulator, and it is corrosion-resistant to have an anti-be full of cracks, good seal performance, and the tensile strength height, price is low, characteristics easy to process.
For addressing the above problem, this plastics composite insulator is made up of interior plug, umbrella shape oversheath and metal-ware.The umbrella shape oversheath adopts low density polyethylene (LDPE), method and interior plug with injection moulding are injection molded into one, become cylindrical in the middle of the interior plug, and two ends are screwed taper shape, interior plug with split lock sleeve kiss-coating thread connection on the transition seat, metal-ware annular link and suspension ring are set on the transition seat.
Advantage of the present utility model is:
1, interior plug is connected with interior plug tapered end with splitting lock sleeve with the cooperation of metal-ware, thereby increases tensile strength.
2, the full skirt oversheath adopts polyethylene to be injection-moulded on the interior plug, increases creepage distance, and solution is inner and the inorganic and organic acid erosion of outer surface discharge formation causes the insulation breakdown problem, improves the life-span of insulator.
The utility model is described in further detail below in conjunction with accompanying drawing;
Fig. 1 is the half-sectioned attitude of front view of the present utility model.
The plastics composite insulator is to be used for the device that supports overhead transmission line conductor and make it to insulate.
The plastics composite insulator is made up of interior plug 2, full skirt oversheath 3 and metal-ware, interior plug and full skirt oversheath are injection-moulded in one, interior plug two ends for band the taper of screw thread with split the locking of lock sleeve 4,6 kiss-coatings, metal-ware suspension ring 5 and ring bulb hanging ring 1 are set respectively above the transition seat 7.
