- Within the medium voltage enclosure voltage measurement transformers can be installed on a withdrawable truck.
- The medium voltage enclosure for switchgears modernizations is designed for the replacement of the existing circuit breakers in the medium voltage switchgear, thus insuring the simple and safe extraction of the modern vacuum or SF6 circuit breaker.
- All the mechanisms of the medium voltage enclosure are designed and manufactured to offer maximum user safety and convenience of use.
- The medium voltage enclosure can be fitted with a whole range of circuit breakers within the medium voltage switchgears:
- capacitor bank;
- transformer;
- radial line;
- interconnected line;
- motor;
- couple;
- input.
