Wholesale Substations vs Site-Built Substations
Site-built substations take months; factory-built prefabricated units arrive tested and connect in days. For multi-site programmes, the factory-built approach is faster and more consistent.
Wholesale supply of standard units also lowers cost through repeat production.
