A piercing connector is a type of electrical connector used to make quick and secure electrical connections in power distribution and transmission systems. It is designed to pierce the insulation of an electrical cable and establish a reliable electrical connection without the need for stripping the cable or using additional tools. Piercing connectors typically consist of a body with multiple piercing teeth, a clamping mechanism, and a terminal for connecting the electrical conductor. They are commonly used in overhead power lines, street lighting systems, and other applications where fast and efficient electrical connections are required. Piercing connectors ensure a strong and stable connection, reducing installation time and labor costs in electrical projects.
