The present invention is for being applicable to height above sea level 3000m and following strain insulator string, and compared with prior art, main feature of the present invention and advantage are:
1, whole string has high reliability, the workload that reduces construction and safeguard.
2, superior performance, corona voltage are far above the requirement of 3000m height above sea level, and circuit operation electricity decreases few.
3, improve preceding lead and easily bump shading ring, do not exist lead to bump the shading ring problem after the improvement, thoroughly solve the lead wear problem.
In addition, gold utensil string of the present invention by the 3rd group two wear the U-shaped link that hangs over together, adjust plate, the 4th group two wear the U-shaped link and the strain clamp that hang over together and form, described the 3rd group two wear the U-shaped link that hangs over together, adjust plate, the 4th group two wear the U-shaped link and the strain clamp that hang over together and be hinged mutually successively, described the 3rd group two other ends of wearing the U-shaped link that hangs over together are hinged and connected on corresponding two yoke plates fixedly connected root lead of the other end of described strain clamp.
Adjust for convenience, make, and adjust plate discord grading ring and collide, the described plate layout that is parallel to each other of respectively adjusting in two gold utensil string length unanimities with layer.
The present invention is fixedly connected grading ring of difference and shading ring on the four eyed yoke plate also.
The present invention also is provided with the support conductor spacer between described six roots of sensation sub-conductor.
The present invention also connects shading ring on described support conductor spacer.
