Between plate, the first insulation sleeve matches equipped with the second insulation sleeve；
Also between the clamp nut and the first insulation sleeve of stainless steel screw tip, the first insulation sleeve and the first galvanized sheet it
Between, between the first galvanized sheet and the second insulation sleeve, between the second insulation sleeve and the second galvanized sheet and the second galvanized sheet bottom surface
The electric insulating sealant being mutually adapted is respectively equipped between stainless steel screw rod, avoids rainwater, dustiness etc. from entering by sealing layer by layer
Chassis interior, influences the insulation effect of lightning arrester base.
First insulation sleeve is equipped with groove type water proof groove, and is equipped with and groove type water proof groove phase on the first galvanized sheet
The convex block of adaptation, groove type water proof groove is matched with convex block to be equipped with, and is further prevented rainwater, dustiness etc. from entering chassis interior, is influenced
The insulation effect of lightning arrester base.
The joint face of first galvanized sheet and the second insulation sleeve is equipped with two raised fixture blocks, the distance of two fixture blocks and the
The equal length of two insulation sleeves, when assembling, can block the second insulation sleeve, play physics and block water, strengthen the effect of leakproofness.
The base of the utility model polymeric metal oxide surge arrester, by stainless steel screw rod peripheral hardware insulating cement,
Play the role of insulation and corrosion-resistant.Electric insulating sealant, and physics waterproofing device are also set layer by layer between each connecting component,
Prevent stainless steel screw rod because getting rusty and the creep distance that causes to insulate such as exterior dustiness reduces, cause the phenomenon that insulation is zero.
