The anti-power-down protection device is suitable for low-voltage insulated distribution lines of 1KV and below on both sides of the tie switch, at the joints of branch poles and tension poles, and at the branch line points that may be reversed (or the branch line with a three-phase power meter installed) The grounding protection of the grounding point of the power failure should be set on the wire of the power failure. characteristic: 1. Keep the line in an insulated state and eliminate the hidden danger of electric shock 2. Easy to install, open the button to connect the ground wire directly 3. The combination of wire protection copper foil and insulating tape greatly enhances the anti-oxidation performance of the conductor and improves the life of the cable 4. Double protection, that is to prevent water vapor or air from entering the interface, and ensure the insulation effect when the interface is not in use 5. It can be reused and has the same life as the wire. It is an energy-saving and environmentally friendly product. 6. Stable product performance, maintenance-free, maintenance-free, greatly reducing maintenance costs Install: 1. Strip the wire insulation about 70-75mm, 2. Wrap tinned copper foil to protect the cable conductors, 3. Wrap 5-8 layers of electrical tape around the ends of the two insulating layers, 4. Cut the length of the waterproof sealing tape according to the installed wire section, wrap both ends, 5. Install the anti-shock insulating protective cover, fasten the buckles one by one, 6.
