The Challenge
UK DNOs operate under stringent ENATS specifications, EU EcoDesign Tier 2 loss requirements and BS EN standards. Transformers must perform in varied climatic conditions — from Scottish Highlands to coastal installations — while meeting exacting factory acceptance test protocols.
Our Solution
Our transformers are designed and manufactured to ENATS 35-1, 35-2 and 35-6 specifications as standard. Every unit undergoes witnessed factory acceptance testing per DNO protocols. We've passed rigorous supplier audits by UKPN (2022) and NIE Networks (2023), with NPG qualification in progress.
