BV 1251103

Our devices are operated in areas with high risk of explosion such as the mining industry. We need a transformer that can transform the primary voltrage of 3300 to one phase mains voltage of 230 V. At the same time fluctuation voltages and voltage peaks of up to 40.000 V need to be blocked and stopped by the transformer isolation.

Solution

We developed a transformer which has very high dielectric strength both on primary and secondary. It is designed to withstand surge voltages of 40 kV. The complicated demand for high isolation with very little volume is done by optimising the combination of foil isolation, vacuum potting, screening and field control.
