TMsec
36kV medium voltage switchgear for secondary distribution air insulated
T.M. has designed, built, tested and patented for the Innovative and Compact Design the TMsec Medium Voltage switchboard for secondary distribution up to 24KV air-insulated, composed of a wide range of functional units, studied and designed to offer the user a multiplicity of uses and the possibility of responding to the most varied system needs; in the design of the compartments, functionality, the simplicity of the operating and locking devices and a long period of operation without maintenance were taken into consideration.
The system is sized to minimize the overall dimensions, while maintaining high safety conditions for personnel, according to current regulations and is particularly suitable for secondary distribution and for transformation cabins. Thanks to their small size, the panels are suitable for use in various types of cabins (compact, mobile and underground prefabricated cabins). All the equipment installed in the TMsec (switches, disconnectors, circuit breakers and fuses) are removable to facilitate maintenance and replacements.
Standard functional units, with integrated auxiliary circuit instrument compartment:
- Unit type IF – IF/R – IF/L: Line entry – L 150-375mm
- Unit type FL: Line departure – L 375-500mm
- Unit type FF: Line departure with fuse – L 375-500mm
- Unit type FF/VT: Unit with fuse and TV – L 500mm
- Unit type FF/VT – C: Line departure with fuse, TV and cable exit – L 500mm
- Unit type FL/CTVT – FL/CT – FL/VT: Line departure with CT/TV – L 750mm
- Unit type IL/TOVT – IL/TO – IL/CTVT – IL/CT – IL/VT: Line arrival with CT/TV and switch – L 750mm
- Unit type BTR/CTCV – BTR/CT – BTR/VT: Riser connector with CT/TV and switch – L 750mm
