Each substation is fully ASTA Certified and our dedicated switchgear engineers expertly install and commission both the HV and LV sides, ensuring all systems – including life safety interlocks – offer the optimum in performance. MV options are made up from compact ring main units (RMU), circuit breakers or disconnecting switches.

Our substations incorporate a choice of transformers as well as leading MV switchgear and our own custom-built LV distribution products. Each unit is tailored to your needs and offers the engineering excellence you would expect from Anord Mardix.
