HT Switch-gear  Panel

 

This specification covers the supply of 11KV indoor,metal-clad, switch-gear according to IEC publication 298, BSS227, 2631, 3659 and VDE 0670 /6.

The medium voltage switch-gear panel shall be used for secondary distribution sub–station up to 12KV & suitable for an ambient temperature of 45 Deg. Cand rated rupture capacity of 350 MVA complete with all accessories ,diagrams, levels, wiring & terminals.

The 11KV, 350 MVA rated  switch  board  would comply compulsory electricity regulations by standards. All cubicles are fitted with security interlocks and earthing switch (i.e isolate to earth switch).

The erection of the panel can be done directly on the leveled floor. Cable trenches are necessary. Cables can easily installed from the bottom side of the panel

The design is done to allow safe operation in extremely tropical climate conditions.
