Metal Clad Medium Voltage Switchgear up to 24kV

T.M. has realized and tested TMclad an Medium Voltage air-insulated switchgear for primary distribution. It’s composed by modular prefabricated unit for interior, combinable with a metallic shell, module/container TMPowerCube, and equipped with extractable circuit breaker in SF6 or vacuum type. Those devices are interchangeable inside the same unit.



They are available in two different versions: TMPC / M and TMPC / E and they are pre-assembled and tested at the factory and allows the creation of frameworks in accordance with IEC 62271-200, IEC 60694, IEC 17-1, CEI 17-6.

• TMPC / M: complete module including the access compartment for cables which could be arranged for withdrawable VT.
• TMPC / E: container without the cell-free cables access and so without the possibility of including a withdrawable VT, but thanks to its smaller size is more flexible and is useful for the creation of double-level switchboard. It’s the perfect solution for medium voltage in case of small spaces.

TMclad main characteristics:

• Vast range of functional unit.
• Modular and gearing of electric and mechanic interlocks for the maximum security.
• Simplicity of Installation and maintenance.

Available with:

• Rated voltage: up to 24KV.
• Rated current: 630A - 4000A.
• Rated short-time withstand current of the main circuit: 25kA 3sec. - 40KA 3sec. - 50KA 1sec.
• Internal Arc up to 31,5kA 1sec.
• Standard External protection degree: IP30, other IP degrees under request.

In TMPowerCube modules It’s possible to install the following devices. Vacuum circuit breaker, SF6 circuit breaker, Vacuum Contactors, service and earthing modules: VD4, VM1 and Vmax series, HD4, V-Contact VSC, each operation is performed on the front of the module/container. Thanks to its characteristics, TMclad range is perfect for every kind of needs guaranteeing service continuity and personnel security.
