Standards and technical information
Medium voltage special applicationswitchgear system
The RAWA switchgear system is a special application solution,
designed for operation in dusty and gassy environments.
The most significant critical operation is in mine underground power networks.
They can operate as underground main switchgears and mine divisional
switchgears.

The RAWA switchgears have been approved by the Polish StateMining Authority to be used underground in mines.
Cubicles are equipped with modern switching, measuring and controlequipment.
The equipment of the switchgear's single cubicle depends on itsfunction in the switchgear's configuration.
Variety of basic cubicles gives possibility of designing anyconfiguration of the switchgear.
The cubicles are metal-clad, i.e. the three functional compartmentsfor bus-bars, switching apparatus and cable connection areseparated from each other by metal partitions. In addition, the lowvoltage compartment is also metal-clad.
The construction of cubicles is properly reinforced to ensure highresistance to internal electric arc.
The closed door provides full protection against internal arc, all compartments of the cubicle are connected with the internaldecompression chamber by the special blow-out valves which in faultconditions open under pressure of gases generated during electric arcand ensure blow-out of gases to the a.m. decompression chamber.
System of electrical and mechanical interlocks which prevents the erroneous operations.
Construction of metal sheets covered by zinc or aluminum-zinc coating.
Doors, external covers are finished with powdered varnish in colouradjusted to the Customer requirements.
The RAWA switchgears are:
especially for mining industry and polluted areas
indoor
with air insulation
metal-clad
internal decompression of arc gases
blow-out of gases limited to decompression chamber only
truck-mounted design with draw-out circuit breaker
free-standing
compartments separated with metallic partitions
with single bus-bar system
degree of protection IP 54
arc-proof
operational safety for staff
modern
equipped with modern switching apparatus
type-tested and approved for use in undergroundof mines (certificate issued by the Polish State Mining Authority)
The RAWA switchgears are designed for supply and distribution of three-phase
alternative current electric energy at rated voltage up to 12kV and frequency
of 50/60 Hz in mine electric power networks. RAWA is also a special application
switchgear, designed for operation in dusty and gassy environments.
Advanced engineering solutions of switchgears RAWA combined with modern
electrical apparatus of leading international manufacturers ensure their safe
and easy operation and maintenance.
Advantages of RAWA switchgears:
unique and innovative constructional solutions
high resistance to electric arc
various switchgear system configurations
