Insulator crossarm, construction is reasonable, electrical safety, and economy is more preferable.
Technical solution is used by the utility model solves above-mentioned technical problem：A kind of extra-high voltage composite insulation cross arm,
Including insulation compression bar and insulated tension pole, the both ends of the insulation compression bar and insulated tension pole are respectively equipped with flange gold utensil, and insulate compression bar
It is connected with one end of insulated tension pole with tower body, the other end is connected with conducting wire hanging point gold utensil, is connected on conducting wire hanging point gold utensil equal
Pressure ring, insulation compression bar are horizontally disposed with, and insulated tension pole is obliquely installed, it is characterised in that insulation compression bar is by several solid bars edge week
Set and form to uniform intervals, uniform intervals are equipped with several restraint joints to several solid bars vertically.
By such scheme, the restraint joint is made of outer anchor ear and interior lining panel, and the outer anchor ear is regular polygon ring-type
Structure, the processing of interior angle arc transition, the interior lining panel is regular polygon platy structure, and angle is provided with circular groove, described
Circular groove formation circular hole corresponding with outer anchor ear interior angle, the circular hole and the solid bar phase configuration.
By such scheme, the solid bar is made by fiberglass, outer surface crimping silicon rubber umbrella skirt structure.
By such scheme, the insulated tension pole is solid hopkinson bar made of fiberglass, and outer surface crimps silicon rubber umbrella skirt knot
Structure.
By such scheme, the outer anchor ear and interior lining panel are made by fiberglass.
By such scheme, the insulation compression bar and insulated tension pole are two, and two thoroughly do away with one end of edge compression bars and tower body
It is connected, both ends of the other end respectively with the conducting wire hanging point gold utensil are connected, and two thoroughly do away with edge compression bar is set in angle, and two, which thoroughly do away with edge, draws
Bar is obliquely installed, and one end is connected with tower body, and both ends of the other end respectively with conducting wire hanging point gold utensil are connected.
The beneficial effects of the utility model are：A kind of extra-high voltage composite insulation cross arm is provided, is made of several solid bars
Insulate compression bar, effectively prevent the insulation flashover problem in voltage levels composite insulation cross arm, solves voltage levels and answer
Insulator crossarm is closed due to the floating potential problem that sectionalized metallic connects and produces, the solid bar not being segmented compares composite hollow pipe
Material segment processing, can shorten in cross-arm insulated lengths, and composite insulation cross arm cost is declined to a great extent, and stock utilization is big
Width improves.
