Currently, composite insulator product is used for insulating in high pressure and super-pressure AC and DC transmission line of electricity and hanging conducting wire.
It is by glass-epoxy leading-drawing rod, silicon rubber umbrella skirt, gold utensil three parts composition.
Currently, insulator umbrella size disunity, cannot mutually unify with creepage distance, safe distance well.Compound bar
Shape suspension insulator full skirt diameter is smaller so that creepage distance is not high in the process of running for product, and safe distance is not also high, in addition
The power function of product is impacted.
The china national practical new-type patent of 201610522368 .3 of Patent No. discloses a kind of composite rod suspension insulator
Son solves problem above, but when electric wire is swung or twists by wind-force, can cause and insulator interconnecting piece well
The abrasion of position, causes electric wire to be broken, and the device waterproof effect is bad, easy tos produce electrical leakage problems.
Invention content

It is aqueous can good composite rod insulator, being capable of effective solution wire insulation fault rupture and waterproof effect is bad asks
Topic.
The utility model solve above-mentioned technical problem specific technical solution be：The composite rod insulator,
Including core and composite sheath, the both ends of the composite sheath are respectively equipped with an insulation bulge loop, and core is equipped in the bulge loop that insulate,
The outer cover of core between two insulation bulge loops is equipped with composite sheath, and composite sheath is equipped with full skirt, it is characterised in that
The full skirt is made of the big full skirt being arranged alternately and small full skirt, and the insulation bulge loop includes insulation bulge loop I and insulation bulge loop II,
I upper end of insulation bulge loop is provided with connector, and the inner end of connector is provided with the protrusion of preset quantity, the external cladding of protrusion
There are composite sheath, II top of the insulation bulge loop to be fixedly installed shaft, fixing lug boss is fixedly installed above shaft, fixation is convex
Setting is fluted at the top of platform, is provided with tension disc above the fixing lug boss, and the edge of the groove is provided with round and smooth
Anti- ground.
Further, a diameter of 100mm of the big full skirt, the small a diameter of 70mm of full skirt；Small full skirt and adjacent big full skirt
The distance between be 80mm.
Further, the abrasionproof discharge surface is provided with ceramic membrane structure.
Further, the tension disc is fixedly linked by hexagon-headed bolt and fixing lug boss.
The utility model has the beneficial effects that：The design of the shaft and anti-ground, effectively avoid cable with
The swing of wind-force, and the tension disc the problem of cutting off cable generated；The inner end of the connector is provided with the convex of preset quantity
It rises, forms labyrinth type design, effectively prevent the infiltration of moisture, substantially increase water resistance.
