Building a New Electric World

MV Metal enclosed cubicle up to 24 kV

Aplication: Secondary distributionLow Isc level (<20kA/1s)

Type of cubicles:Switch and fuse switchCircuit Breaker (Incoming,Outgoing and Coupler) fixed and draw outDirect incomer or outgoerBusbar metering (CM, GBC-A/B)Other functional (interface VM6, Aux power,intermediate,etc)

SM6MV Metal enclosed Switch cubicle up to 24 kV

Switch Cubicle:Load break switch ( IM)Off load switch (SM)Load break switch with CT (IMC)Fuse load break switch (QM)Fuse Off load swicth (CM, TM)

Max voltage : 24 kV Isc max (24kV) : max 20kA/1s (basic housing) Rating: 630A and 400A BIL : 125 kV earthing switch VPIS on cable side

Switch Cubicle:
