The BRDA switchgear system features:
switchgears have two independent systems of bus-bar
metal-clad with two separate bus-bar compartments
indoor
air insulated
compartments separated with metallic partitions
withdrawable circuit breaker (can be transported outside the cubicle
on a separate trolley)
internal arc tested
equipped with innovative equipment for switching, measurement
and control functions
The innovative double bus-bar switchgear system BRDA is equipped with
apparatus produced by leading international manufacturers which assures high
quality, safety of work and easy maintenance.
Advantages of switchgear BRDA:
innovative construction solutions
high resistance to internal electric arc effect
and arc protection
configuration of different switchgear systems
high service safety
high operational reliability
high corrosion resistance
simple service and maintenance
High safety of operation of MV switchgears BRDA has been obtained due to properly
reinforced cubicle construction and decompression channels, which ensure high
resistance to internal electric arc effect.
In fault conditions the metal covers (blow-out valves) installed on the top of cubicle
open under pressure of gases generating during burning of internal arc and secure
blow-out of these gases out of switchgear.
The construction of BRDA cubicles is made of steel sheets covered by zinc
or aluminum-zinc coating.
Doors and outside shields are covered with powder varnish in a colour adjusted
to the Client’s demands.
The cubicle construction is appropriately strengthened to assure high endurance
of the action of the internal electric arc.
The system of mechanical and electrical interlockings ensures safety of operation.
All compartments are equipped with metal covers to ensure gases blow-out
in fault conditions.
The switchgear system BRDA allows flexible designing of various configurations
of MV part in distribution substations.
MV air insulated, metal-clad double bus-bar switchgears BRDA are designed for primary distribution of AC three-phase
electric energy with a rated frequency of 50/60 Hz and rated voltage up to 17,5 kV in electric power distribution networks
of public utilities and industrial power distribution networks.

Thanks to the double bus-bar solution, the BRDA switchgear may be used
in conditions, where reliability and flexibility of switching operations between two
different power sources secure the continuity of power supply. This is very essential
for objects of critical destination, production plants in processing industry
and in electrical power distribution system of weak networks.
