as preferred technical scheme, the head of described disc ceramic material insulator is hollow cylindrical or hollow conic.
as preferred technical scheme, described disc ceramic material insulator is for exchanging or direct current two layers of dish type umbellate form, interchange or direct current three layers of dish type umbellate form, interchange bell jar dish type umbellate form or direct current bell jar dish type umbellate form.
as preferred technical scheme, the head of described disc ceramic material insulator is connected with described chapeau de fer by lock pin.
as preferred technical scheme, be provided with installation groove at described chapeau de fer top.
advantage of the present invention is:
1. the present invention adopts the head strong bonded of zigzag Asperity model and disc ceramic material insulator, avoid pulling, can can reach 760kN ~ 840kN by resistance to mechanical tensile failing load, relative to traditional highest ranking 550kN product, it can improve 1.3 to 1.5 times by resistance to mechanical tensile failing load, there is more reliable mechanical fit structure, simultaneously safer to the extra high voltage line transformation or newly-built project that reduce string number or increasing conductor cross-section raising transmission line capability, more economical, therefore actual application value is possessed, be applicable to large span, the construction of large-section lead circuit, and meet with increase conductor cross-section measure upgrade the various filthy environment UHV transmission line of China in the urgent need to,
2. the present invention adopts ∧ shape convex body and is fused to the zinc cover of ∧ shape convex body, in the stressed extensional process of steel pin, ∧ shape convex body is held zinc cover and separation does not occur is come off, resistance to mechanical load and security performance high, make the anti-Function of the resistance to galvanic corrosion long term of steel pin simultaneously, increase the service life;
3. the present invention has good mechanical strength, resistance to galvanic corrosion, and life cycle is long, and is implemented in multiple beveled structure and porcelain head load-carrying construction product, and security performance is high, and monolithic required string number is few simultaneously, and production cost is lower.
