Polish Coal Mines

In two of the largest Polish coal mines - kwk Budryk and kwk Zofiówka respectively - which form part of the enterprise JSW S.A. Group, a number of CUBIC switchboards are in operation.
The Multi Drawer panels work on the ground in the coal processing plants. Here coal is transported from the underground, separated from stones and waste, crushed and grinded, and finally washed and selected.

In this mine the largest panel is supplied by 4 transformers via 2000A incomers. It consists of 93 drawers. Another panel supplies two 2000A, and its two sections are fed by a busbar coupler with CUBIC’s busbar trunking system. So far 6 switchboards have been delivered to the mine, and presently CUBIC partner Industry Power Solutions is preparing assembly of the 7th switchboard.

In this mine a panel with 2000A incomers and 70 drawers is in operation. Commissioning takes place at this stage, and therefore a switchboard with many drawers in test and disconnected positions is illustrated. Another panel is applied for the container placed in the demethanisation stations. Methan is dangerous (explosive gas), and highly unwanted in mines. In the mines of JSW S.A. Group methan is pumped out from the underground, and used to generate electricity and heat.
