2021 China New Design 1.2kv 250a Tranformer Bushing - NLL Aluminum strain clamp(Bolt Type) – Johnson

Advantages of strain clamp:

1. Effectively eliminate short circuit accidents caused by overlapping of small animals or foreign bodies;
2. Prevent electrical accidents caused by condensation flash soldering, pollution flash soldering and icicle sticking snow;
3. Prevent acid rain, salt mist and harmful chemical gas from corroding the incoming and outgoing lines of the transformer;
4. Avoid personal injury or death caused by pedestrians touching exposed electrical contacts by mistake;
5. The protective cover and metering device are fully closed to prevent criminals from stealing electricity;
6. Buckle structure, simple installation and reusable.”

Power fittings are widely used in the process of high-voltage power. They also have many different types, which can meet various needs in use, so as to provide certain guarantee for our combination and connection of power system devices, and also play a certain protective role. Moreover, due to the high pressure in operation, it requires us to focus on quality when purchasing and returning products, so as to avoid problems in the use process and cause many unnecessary troubles and losses for the later application process. In addition, the ball joint, support frame and other products also have certain differences in characteristics and functions due to their own differences in production and design. We should also choose and buy according to our own actual needs, so as to give full play to its value in use, better provide services for us and promote the smooth progress of high-voltage power.
