Description

A kind of 220kV cross arm insulators
Technical field
The present invention relates to a kind of transmission line of electricity bar, especially a kind of 220kV cross arm insulators.
Background technology
With developing rapidly for China's electric utility, in transmission line construction, transformation, except part transmission line of electricity is changed to electricity Cable lays outer, and most transmission line of electricity is still using built on stilts form.Aerial transmission line of electricity is maked somebody a mere figurehead by transmission pole, wherein Under fixation and various meteorological conditions to the installation site of the wire and position of stress condition lower wire change all needs to meet electric Regulatory requirements, and the safe distance of transmission line of electricity and installation site are more one of stubborn problems in engineering design.In 220kV The use of cross arm insulator is particularly significant when transmission line of electricity is installed, the transfer wire used in different transmission lines of electricity and connection Structure type it is also just different, the adjustable of this situation lower clamp is particularly important, and high air line angle is difficult to adjust, to peace Dress personnel cause very big influence.And if good general can not cause side to there is deviation to the flexibility of cross arm insulator, make horizontal stroke Carry on a shoulder pole insulator inadequate with the space crossed safe distance of opposite side circuit, and there is potential safety hazard.
The content of the invention
In view of this, the purpose of the present invention is that there is provided install spirit suitable for high bending strength in view of the shortcomings of the prior art Cross arm insulator living.
A kind of 220kV cross arm insulators of the present invention, it is characterised in that:A kind of 220kV cross arm insulators, it is characterised in that: Including clamp, connector, the diplopore fixed plate of two kinds of structure type, umbrella cover, plug, bolt assembly, described two structure types Diplopore fixed plate be crimped on by compression joint technique on plug, the umbrella cover is by injection technique integral injection molding in plug On, the clamp is fixed on connector by bolt assembly, and the connector is arranged on diplopore fixed plate by bolt assembly On.
Further, the plug is diameter 80mm, length 2350mm ECR acid-resistant and anti-high-temperature plugs, can bear 10kN Bending strength.
The further connector is L-shaped, and its number can be actually needed according to circuit and be adjusted.
Further, the clamp uses V-shaped groove structure.
The beneficial effects of the invention are as follows:Product of the present invention is supported the use with transmission line of electricity tubular shaped base, wire installation direction Arbitrary Rotation can be carried out to bottom, it is its simple structure, easy for installation, it can be widely popularized.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Fig. 2 is component diagram of the invention.
