What Substation voltage classes do you handle?

We work on 11 kV Distribution Substations through to 132 kV and 220 kV transmission Substations, in both AIS and GIS configurations.

Do you supply the transformers and switchgear?

Yes — we can supply all primary and secondary equipment through our approved vendor network, or work with client-nominated suppliers.

How long does a 33/11 kV Substation typically take?

A greenfield 33/11 kV Substation typically takes 6–9 months from design approval to energisation, depending on equipment delivery lead times.
