PREM-GO IV-* flameproof distribution field is dedicated for electrical energy distribution in alternating current grids with rated frequency of 50 Hz and operating voltage 6 kV. Primarily in underground mining plants.
PREM-GO IV-* flameproof distribution field is designed for methane-free and methane areas, mining headings classified under methane explosion and coal dust explosion hazard categories.
Equipment will automatically trip-off in case if allowed methane gas concentration will be exceeded.
Flameproof distribution field, PREM-GO IV-* is a field full compartmental in a metal flameproof enclosure, whose components are located in separate compartments of reduced metal partitions. The field is fully assembled with the exception of external connections.
The introduction of cable / wire to the inside of the cover is done by certified busbars and cable entries. Flameproof enclosure "d" provides protection against dust and water to IP 54. Flameproof distribution field PREM-GO IV-* can be configured depending on the type of equipment used, switches the main circuit.
The autonomous version predisposes the flameproof distribution field for installation in the one or multi-section distribution systems.
In order to realize the multifield and sectional distributor the following distribution field versions are foreseen: incoming, outgoing, coupling versions and on-load switch.
