Trailing Cable Couplers

UEE quick-connect couplers reliably connect high-voltage supply feeds to shovels, drilling rigs and other open-pit and underground mining equipment. UEE couplers can also be used to connect low-voltage motors, fans, pumps or other mobile electrical equipment. Our quick-connect coupler system allows unsurpassed reliability and safety without compromising quick-connect convenience. UEE couplers are designed and engineered to meet and exceed CSA 22.2 298 High Voltage Coupler standards.

The UEE conductor arrangement ensures that power cannot be turned on until the couplers are completely connected. Should a coupler in a live circuit be disconnected, power shuts down at the source the instant the ground-check circuit is opened. To increase the safety and reliability of our medium to high-voltage couplers (8kV to 25kV), UEE has incorporated a comprehensive phase-isolating ground shield system to eliminate phase-to-phase faults. 

Collet System

Select UEE couplers utilize our patented Collet System (Canadian Patent Number #2271589), a securing system that eliminates messy solder- type connections by uniformly and securely compressing phase wires for a simple, reliable and low-resistance connection. In a collet-equipped coupler, as a phase wire inserts into the collet, a bolt draws the collet into the phase conductor. As the collet is drawn into the phase conductor, the phase wire is gripped for optimum connection.
