Flexible couplings for transformer stations

Description

Złączki elastyczne do stacji transformatorowych

Application:

Flexible couplings for the main chamber of flameproof transformers type IT3S … and the series of types of flameproof transformer stations type MAR-…..

Flexible couplings are used to make connections between the lower DN side of the transformer core and the bushings of the lower DN side of flameproof transformers IT3S … and the series of flameproof transformer stations type MAR-…..

Construction

  • Flexible couplings are made of 2×4 braided lines PLC
  • The ends of the couplings are pressed in copper sleeves.
  • Mounting holes are drilled in the pressed ends of the connectors.
  • The pressed ends of the connectors are galvanized with zinc.
