The other end is connected to the lower end of the insulating forward-extending pipe. The two inclined insulating supporting pipes are V-shaped. The metal fixing base is evenly connected with two ratchet bracket holders. The front end of the insulating forward-extending pipe is evenly connected to the drainage wire fixing groove.

In order to further realize the purpose of the present invention, the ratchet bracket fixer is composed of a ratchet cable tie and a cable tie fixing hook.

In order to further realize the object of the present invention, there are three said drainage wire fixing grooves.

In order to further realize the purpose of the present invention, the distance between two adjacent drainage wire fixing grooves is 0.6-0.8 meters.

In order to further realize the purpose of the present invention, the vertical distance between the insulating forward pipe and the metal fixing base is 0.8-1.2 meters.

Compared with the prior art, the present invention can produce the following positive effects: the present invention solves the problems of small safety factor and inconvenient operation when using insulating blankets for insulating and shielding through the hard insulating isolating device. The insulating bracket of the drain wire insulates and supports the live drain wire, keeps a sufficient safe distance from the shaft, extends the gas discharge path, and increases the discharge voltage value. The safety of the person and the power grid is guaranteed. After the application of the equipment, the potential safety hazards in the work of replacing the lead wires on the high voltage side of the transformer with load are eliminated, the reliable and stable operation of the equipment is guaranteed, and the reliability of power supply is improved.

1. Simple structure and easy installation. When using the insulating bracket of the drain wire, the bracket is fixed on the shaft through the ratchet bracket holder; the insulating pipe plays the role of main insulation, keeping a sufficient safe distance between the electrified body and the grounding body; the function of the drain wire fixing groove is to lock the lead wire to prevent artificial , The action of wind causes the drainage line to swing.

2. The equipment is reliable in performance, mature in technology, perfect in function and reasonable in structure, meeting the requirements of long-term charged and stable work.

3. High safety factor. It can help to improve the safety factor of live workers during the work process, effectively reduce unnecessary insulation shielding, improve work efficiency, and avoid unnecessary losses caused by human misoperation.

After using the insulating partition of the drop-out fuse, the problems of small safety factor and inconvenient operation using the insulating blanket are solved, the reliable and stable operation of the equipment is ensured, and the reliability of power supply is improved.
