It is further improved according to above-mentioned technical proposal, the material of lower cushion block includes rubber.
The beneficial effects of the utility model are：The utility model by being provided through stopper slot in the middle part of upper cushion block, under
The top of cushion block is provided with the projection being engaged with stopper slot, the nested bottom set with stopper slot of projection, the bottom of lower cushion block
Locating slot is offered, instead of and cross-over block is placed between coil and folder from top to bottom in conventional mounting technique, by pressing from both sides up and down
The mounting means that part compresses, avoid and be easily shifted over causing unshakable in one's determination collide with coil to cause insulation damages, generation short
Road phenomenon, cause the problem of power failure, the utility model can effectively limit the position of high and low pressure coil, it is ensured that high-voltage line
Spacing distance between circle, low-voltage coil, improve the stability of transformer station high-voltage side bus.
