HV Substation Services

Fundamentals has extended capabilities in the field of HV substation maintenance, refurbishment and installations. Covering voltage levels from low voltage to 400kV, our multi-skilled engineers and technicians maintain and install a diverse range of substation equipment of differing manufacturers and models. Our authorised staff are highly trained and experienced for this safety-critical industry.

With engineers and technicians based throughout the UK, our specialist expertise can be relied upon to meet your ever changing requirements.  Fundamentals can activate resources at relatively short notice to meet an emergency situation or unplanned disruptions to our customer’s networks and installations – available 24 hours, seven days a week.  Steps are taken to minimise down-time with the deployment of our on-site mobile workshops.

The scope of major substation equipment includes:

  • Transformers/ tap-changers
  • Switchgear
  • Disconnectors
  • Earth switches and LNERs
  • HV & LV bushings
  • Protection and control systems
  • Cooling systems

Whilst traditionally strong in the generation sector (power stations), our customer base also extends to Transmission System Operators, Distribution Network Operators and large industrial customers.

With Ofgem insisting on value for money from the network operators for the RIIO period (2015 to 2023), refurbishment programmes and condition-based maintenance represent two key strategies for delivering extended plant life, while maintaining a reliable and resilient power network.  Fundamentals is here to help our customers achieve their aspirations.
