Transmission & Distribution

UK manufacturers can supply a range of equipment from large transformers, HVDC and protection relay equipment to low voltage transformers, switchgear and smart meters.  

 Other key transmission system components manufactured in the UK include FACTS (Flexible AC Transmission System) equipment, such as conventional static VAR compensators (SVC) and novel Statcom devices which control voltage directly. Quadrature boosters, which enable variable line compensation, are another leading-edge HV network control device designed and manufactured in this country. UK companies are able to design and manufacture a range of transformers, switchgear and protection equipment.  This includes a wide variety of distribution, power, dry type, cast resin and traction transformers, along with flameproof transformers and switchgear.

In addition to these equipment manufacturers, the UK has a number of major companies providing engineering, procurement and construction (EPC) services in the development of substation and transmission equipment and power lines (overhead, underground and sub-sea).  Most of these companies also provide bespoke refurbishment, maintenance and spares for existing assets.  In terms of asset management, the UK is a leader in condition monitoring and service quality monitoring. National Grid is a major international owner/operator of transmission assets and the UK leads the world in regulatory, operational and asset management innovation in both transmission and distribution.

Major UK companies working in this area include Balfour Beatty (whole power transmission and distribution networks), Areva T&D (construction of high and medium voltage substations, power grid management), EA Technology (power asset management), Brush Transformers (manufacture of distribution, power, dry type, traction and flameproof transformers) and Lucy Switchgear (switching and protection solutions for electrical distribution systems).
