Description
1、Overview
The equipotential meter connector produced by Lefedi uses a metal shell, beautiful appearance, convenient installation and wiring, dust-proof, anti-corrosion, explosion-proof, and flame-retardant functions. It is suitable for the voltage equalization connection between two different grounding systems to form, etc. Potentiometer. Through the connection of this product, each grounding system is independent when there is no large current discharge such as thunder and lightning; when a large current such as thunder and lightning leaks into the grounding system, the product is quickly turned on, so that the potential of each connection pool system is raised at the same time , Forming an equipotential body.
2、working principle
Under normal circumstances, both ends of the equipotential connector are in a high impedance state. When there is a potential difference between the grounding systems, this product will quickly turn on, so that an equipotential body is formed between the two grounding systems, and the potential difference between the grounding systems is eliminated.

4、Features
1) The product adopts metal shell, beautiful appearance, convenient installation and wiring, dustproof, anti-corrosion, explosion-proof and flame-retardant functions;
2) The product adopts the principle of event-level leakage current, which has the characteristics of low starting voltage and large discharge current.
5、Installation, use and maintenance
1) Fix the equipotential connector at the selected installation position, and connect the two external grounding terminals to two different grounding systems that need equipotential connection.
2) After the connection is completed and the sealing is confirmed, the product can be put into use;
3) This equipotential connector does not require special maintenance during normal use.
