35BU Range – 35,000 Volts | 800 Amp | High Voltage Coupler

Exclusive to KonNx UK and its sister companies, the 35kV aluminium high voltage coupler is the only coupler in the world capable of withstanding 35,000 volts.

Developed in a staggering 15 weeks, the 35BU was released in 2013 after international partner company AusProof was approached by a client who was unable to find a product suitable on the market to meet their needs. Popularly used in South America, Asia and Europe, common applications of the 35BU include the supply of power from overhead lines to mobile transformers, as well as supplying power to dredges. The 35BU also features a guide pin that will become enclosed in the body casting of the coupler when the system is closed, protecting it from external damage.
