Specialist product · GM-Z

Are you looking for medium-voltage busway?

GM-Z is a cast-resin busway built for medium-voltage power: typically the link between generators, transformers and switchgear in power plants and large industrial sites.

It is engineered and quoted project by project. Most commercial and industrial buildings need a low-voltage system such as LVA or GM instead.
