An integral part of each mining complex is the electrical equipment necessary for powering and controlling individual devices. In this area, T Machinery a.s. offers APK9U contactor set for switching up to nine independent MFK400 frequency inverter drives for powering and regulation of the travel equipment of shearers and auxiliary voltage transformation. All of these devices have outputs that allow the transfer of traffic information to both the other devices in the complex and to the dispatching station on the mine surface.
All the electrical devices supplied by us are manufactured in accordance with the requirements of Directive 2014/34/EU (ATEX) and in accordance with the equivalent directives of the Russian Federation and Ukraine.
