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 tin-plated, 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.

UL Listed 90° C,
600 Volts to 35 kV
