Medium Voltage Switchgear

Medium Voltage Switchgear

(OP)
hello, what does two-stack type switchgear means?

RE: Medium Voltage Switchgear

Two breakers, one above the other, in a single cubicle of gear.

Hello, davidbeach do you have brands which use the two-stack type?
Was it ANSI or IEC?

RE: Medium Voltage Switchgear

All ANSI, but every line of switchgear I’ve looked at includes stacks as well as singles. No idea about life in the IEC world.

RE: Medium Voltage Switchgear

Hi, It implies that breakers are arranged in 2 tier fashion, 2 breakers in a vertical section.

1. If you look into any manufacturer LV switchgear catalogues, you will see what is "two-stack" as explained. For LV switchgear there are even "three-stack".
2. For MV due to bigger physical size up to say 22kV with vacuum or SF6 breakers, there are "two-stack" design available on the market.
3. This is applicable to IEC or ANSI world.

RE: Medium Voltage Switchgear

Low voltage is 4, medium voltage is 2. Low voltage is almost always 4, but for MV, industrial/commercial customers almost always go 2 but utility customers often limit it to one per section.
