Reliable Heavy-Duty Cable Termination for Industrial Power Distribution
Copper tube ring terminals provide a dependable method of connecting large electrical conductors to switchgear, busbars, distribution equipment and other bolted electrical connection points. The tubular barrel is compressed around a correctly prepared conductor using suitable crimping equipment, creating a secure mechanical and electrical termination. Copper construction helps maintain effective electrical conductivity at the connection when the terminal is correctly selected and installed.
The Partex COL300-12 combines a 300 mm² conductor connection with an M12 ring palm, making it suitable for applications requiring large power cable terminations and compatible bolted fastening arrangements. Correct conductor preparation, crimp die selection, compression procedures and fastening torque are essential for achieving dependable electrical performance and minimising the risk of connection overheating.
