Abstract: Connect the consumer on the low-voltage line, and the connection mode of the customer meter connecting line and the incoming line mostly adopts the direct winding mode. With the increase of people's demand for electricity, this connection method has many shortcomings. It is easy to oxidize and loosen after a long time, which is easy to cause the conductor to heat and burn out, and the construction time is long. The clamp connection gradually replaces the direct winding connection. However, the current clamp installation is time-consuming and laborious, and there are certain potential safety hazards. Therefore, a fast connecting clamp is developed. The clamp can realize the universality of most conductors, and is easy to operate and save time and effort.
