64BKA | Aluminium High Voltage Open-Cut Coupler
Rated for 800 amps with an operating voltage of 6,600 volts, the 64BKA has an ingress protection rating of IP68, far exceeding the required Australian standard of IP55.
Suitable for use in Non-Ex operational environments, such as open-cut and metalliferous mining, pumps and tunnelling projects, the design of the 64BKA was inspired by AusProof’s aluminium 11kV 4-bolt coupler. The intention was to create a smaller and lighter 4-bolt coupler for the reduced operating voltage of 6,600 volts. Its design also allows for the guide pin to be enclosed within the body of the casting upon closure of the coupler system, protecting the pin from external damage.
