Substations

As an Independent Connections Provider (ICP) trusted by organisations across the United Kingdom, Network Power Connections are experts in substation design, installation and maintenance services. Our qualified electrical and civil engineers are able to deliver entire projects from concept to delivery, including the installation of plant equipment in a live substation environment. The electrical substation is a key component of any electrical infrastructure and, with there being an increased demand for companies to maximise output with minimal disruption, your company will need one that can do both.

Whether you require a brand-new substation or complete maintenance of existing assets, our carefully selected engineers and technicians are experts at facilitating and delivering all of your substation requirements. We offer yearly inspection programs, planned maintenance works alongside a complete substation management service.

What is an electrical substation?

The substation is a key component of the electrical generation, transmission and distribution system. They’re used to reduce the voltage of electricity so that it is safe to transfer into homes and businesses; alternatively they can also be used to transform voltage from low-to-high if necessary. 

Typically, you’ll find that substations are divided into three major types:

  • Transmission substations
  • Sub-transmission substations
  • Distribution substations

The size of the substation will usually depend on it’s usage; for example, whether it caters for residential properties or an industrial park. However, there are facilities such as schools and hospitals that often have their own.

Electrical Substation Design

From the very beginning, we pay attention to every detail, ensuring all due diligence is done in order to deliver the project to the highest industry standards. We’ve got a proven record in the delivery of major substation replacements in towns and cities across the United Kingdom; some of which were under very challenging circumstances. It’s our meticulous planning and expertise that allowed us to complete these projects inline with customer expectations.

Network Power Connections undertake in-depth analytical work, conducting thorough risk assessments and identifying appropriate actions to mitigate them. We’ll also be clear upfront during the pre-tender stage about what needs to be done, minimising any changes later down the line that could affect time, cost and quality. In addition, we’ll create an achievable delivery programme that takes into account local network constraints and any site limitations.

Our experts are able to provide a wide-range of coherent electrical substation design services including:

  • Surveying & Construction
  • Regular maintenance and complete refurbishment
  • Comprehensive testing for SF6 (Sulphur Hexafluoride)
  • In-depth Substation Grading and Protection Services
  • The production of in-depth technical reports
  • Design and Installation of Cable/Overhead Lines Support Structures
  • Senior Authorised Persons (SAP)
  • Safety Stand by

Electrical Substation Installation

Network Power Connections have a wealth of expertise overseeing the installation and replacement of electrical substations. Our highly-experienced, professional electrical engineers and technicians have a wealth of expertise in the installation of switchgear, transformers and associated cabling. They’re also able to undertake terminations and commissioning.

We’ll keep you updated on all construction progress and carry out a thorough inspection upon work completion. Furthermore, we can also complete an as-built survey of the completed works.

Electrical Substation Maintenance

In accordance with the Electricity at Work Act 1989 regulation, all privately-owned high-voltage equipment and networks must be maintained to operate safely. They’re also required to be “fail safe” under faulty conditions. Therefore it’s essential that you work with a highly-experienced, trustworthy Independent Connections Provider who can keep your substation in optimum condition. 

There’s multiple benefits to ensuring your electrical substation remains well maintained; chiefly that it prevents equipment failure and a complete loss of power. Your finances will also benefit, as regular maintenance prolongs the life of your high-voltage and low-voltage assets.

Need emergency support? No problem, our maintenance experts can rapidly deploy at short notice to restore power supplies and provide replacement high-voltage or low-voltage equipment as necessary. Furthermore, they can also trace and rectify any cable and equipment failures, identifying the root cause to ensure it doesn’t happen again.
