BURNDY® compression connectors are designed for reliable and controllable electrical connections. The complete installation is fully inspectable. They are high conductivity copper and operate cooler than the wire on which they are installed. The connectors withstand a wide range of electrical and environmental conditions, including current surges, temperatures, corrosion and vibrations, for a wide variety of applications. These features mean a consistently high quality connection at a low installed cost. Copper compression connectors are manufactured from high conductivity electrolytic copper. The connectors are normally tinplated, lead plated or plated with proprietary BURNDY® brite finish to provide durable long lasting corrosion resistance. The connector design has been matched to the cable Size to provide the necessary physical strength requirements for reliable electrical performance.
