35BU | Aluminium High Voltage Open-Cut Coupler
Exclusive to AusProof and its sister companies, the 35BU is the only coupler in the world capable of withstanding 35,000 volts.
Released in 2013, the 35,000 volt coupler was developed in just 15 weeks after AusProof was approached by a client who required a coupler capable of operating at 35kV and had been unable to find an existing product to meet this need. Popularly used in Africa, Asia, Europe, and South America, some installations of the 35BU across South America include high altitude sites, with no issues reported. Common applications of the 35BU include supply of power from overhead lines to mobile transformers, as well as supplying power to dredges. Rated for 800A, the design of 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.
