AMC ( A ir-insulated M etal C lad) panels are type-tested, air-insulated, metal-clad units which can be assembled side-by-side.Ormazabal AMC switchgear assemblies satisfy the international requirements for air-insulated metal-clad switchgear assemblies.Switchgear in withdrawable techniqueFour metal-clad compartments Drawer units with vacuum circuit-breaker Drawer units with vacuum load-break switch Drawer units with vacuum contactor Standard current and voltage transformers All standard types of protection and control systems can be usedSuitable for combined protection and control systems,...

Configuration of the cable connection compartment Configuration of the busbar compartment The cable connection compartment offers a multitude of standard and customer option equipment with:Current and voltage transformersՕVoltage transformers with primary fuses Earthing switch ՕSurge arrestor Three-phase medium voltage capacitor ՕHRC fuse baseDepending on the panel version up to three cable systems per phase can be connected in AMC6 panels and up to six cable systems per phase in AMC9 panels. The panel floor is sheet-metal. In the bus sectionaliser panel versions, the compartment contains...

Cable installation The medium voltage cables can be installed from the front of the panel. The cable connection compartment is easily accessible and has a separate compartment door. After the drawer unit has been removed out of the panel, the front cross-spar of the panel and the plate between the drawer unit compartment and cable connection compartment can be removed with a few movements, for additional ease of installation of cables in the cable connection compartment.The maximum cable cross-sections that can be attached at the cable connections at the panels are as follows: AMC6 =...

Interlocking system Operation at the panel The interlocking of panel components according to VDE0671 part 200 respectively IEC62271-200 and optional additional interlocking features of type AMC panels, in connection with the metal-clad panel design, form a safe system and also assist the operator in performance of his operations. To ensure quick and reliable operation of the panel, the operating and display elements are positioned for clear viewing and for clear association. Capacitive voltage detection systems for the outgoing cables and/or main busbars can be equipped as options. The...
