Shrunk type pendency strain insulator tangent tower used for transmission line, including post insulator substring and strain insulator string, it is described
Post insulator substring is vertical to be fixed on the first cross-arm, and the strain insulator string is horizontally disposed, is located at same route
On strain insulator string be connected after overhung structure, and strain insulator be fixedly connected to form by fitting and the second cross-arm vertically
The conducting wire at string both ends is connected by wire jumper with the fitting on the post insulator substring on the first cross-arm；Using post insulator substring control
Wire jumper processed around hop distance, guarantee safe distance.
Further, positioned at two of the same line road close between strain insulator string by apart from adjustment plate phase
Even, by the way that the distance between strain insulator string is adjusted apart from adjustment plate, the middle position apart from adjustment plate with one
The connection fitting being vertically arranged is connected with cross-arm, ultimately forms overhung structure.
Further, the post insulator substring is made of support insulator and connecting tool, the connection fitting of upper end with
Wire jumper is connected；The connection fitting of lower end is connected with cross-arm；For controlling wire jumper far from tower body, flexible jumper windage yaw is limited.
Further, the shrunk type pendency strain insulator tangent tower can be the power transmission lines such as angle steel tower, steel pipe pole or steel tube tower
Line pole tower.
Further, the overhang tension insulator string includes suspension insulator or composite insulator and connecting tool group
At.

From.
The beneficial effects of the utility model are:
Overhung structure is formed by post insulator substring and strain insulator string in the utility model to cooperate to control
The windage yaw distance of wire jumper；So that cross-arm is long to be only dependent upon wire spacing requirement, cross-arm shortens, and width of corridor is effectively compressed, on road
The nervous area of diameter, reduces channel removal；Far from tower body, equivalent string is long to be shortened electrical body, is improved steel tower and is effectively exhaled height；Strain insulator
Insulator is horizontally disposed, enhances wind and rain self-cleaning property, improves the anti-pollution performance of insulator；The weight of steel tower is reduced simultaneously,
Save ontology investment.
