Flexible couplings for transformer stations
Description
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.
