Primary and secondary MV switchgears

Main advantage of Electroshield-Samara as a builder of MV Switchgears is the ability to combine individual approach with the mass production speed. The plant is able to produce more than 1000 cubicles per month, and the significant part is produced upon the individual customer’s requests.

Main accessories (protection relays, vacuum circuit breakers, measuring transformers, voltage transformers, earthing switches) of own production.
Processing with electrophoretic prime coating method of painted metallic parts of cubicles that increases corrosion resistance.
Earthing switches with spring adjustment.
Tulips of circuit-breakers, their mating parts in the cabinet are made of copper with additional silver layer coating.
GOST certificates for the equipment and declaration of compliance.
ISO 9001 international quality management system compliance certificate.
Certification for JSC «FSK EEС» and JSC «Rosseti» confirmed.
