Cast Resin Transformers
Cast resin power transformers for distribution networks and for special applications with rated power up to 20MVA-52kV, wind and photovoltaic plants, rectifiers, AC/DC industrial conversion and electrical traction.
Oil power transformers for distribution networks and for special applications with rated power up to 10MVA-36kV.
Metering transformers for distribution networks and for special applications such as current transformers with rated nominal currents up to 3.000A, ring type current transformers with primary currents up to 20.000A and voltage transformers with insulation level up to 36 kV.
SYStem6 12÷36 kV
SYStem6 switchboards are composed by modular panels metal-enclosed type, equipped with SF6 insulated on-load switches and vacuum circuit breaker.
RMSYS is suitable for secondary power distribution, fully SF6 insulated and fully extensible.
MV switchboards metal-clad type, equipped with withdrawable vacuum circuit breaker; suitable for the primary distribution. Rated current up to 3150A, with short-circuit current up to 40kA.
On-load switches with three positions (open, closed, earthed); composed by an epoxy cast resin housing filled with SF6 gas. Commonly use in SYStem6.
IM6 12kV (210mm)
Special on-load switches of IM6 series with phase center of 210mm. Rated voltage up to 12kV.
On-load switches for outdoor installation, suitable for use on overhead lines. Manual or motorized versions available.
MV Circuit Breakers
Medium voltage vacuum circuit breakers for indoor installation, with lateral or frontal operating mechanism; the vacuum interrupters are encapsulated for better performance and minimum maintenance. Generally use in SYStem6.
Medium voltage vacuum circuit breakers for indoor installation with frontal operating mechanism, like in WL breakers, the vacuum interrupters are encapsulated for better performance and minimum maintenance, available in withdrawable and fixed type; generally use in SYSclad. Rated current up to 3150A with short-circuit current up to 40kA.
