Pre-Commissioning, also known as “Pre-functional Testing,” is an essential step in the installation and implementation of Low & High Voltage Electrical Power Systems – this process ensures that all components and cable accessories of the system are functioning properly and safely before the system is put into operation or “Commissioned“.

High voltage systems are critical to the operation of many industries, including utilities, manufacturing, data centres and commercial buildings. These HV systems are responsible for distributing and transmitting electrical power, and any failure or malfunction can have serious consequences, including injury, property damage, and loss of revenue.

Commissioning is a comprehensive process that involves testing and verifying the performance of all components in a high voltage system. This includes electrical and mechanical components, such as transformers, switchgear, protective devices, and control systems. The commissioning team will also verify that the system meets all safety and technical standards, and ensure that it is properly grounded and bonded.

In addition to ensuring the safety and reliability of the system, pre-commissioning can also identify potential issues and improve the overall performance of the system. This can save time and money by preventing costly repairs, mal-operation and downtime in the future.

Oakes Power Services is a leading provider of commissioning services for Low & High Voltage Electrical Power Systems – their team of experienced professionals have extensive knowledge and expertise in testing and verifying the performance of these systems using the latest tools and technology to ensure that your system is safe and operational

Oakes Power Services provide ongoing support and maintenance to keep LV HV power running smoothly.

By partnering with Oakes Power Services for your commissioning needs, you can have peace of mind knowing that your network is in good hands.

Ellis Patents Cable Cleats

Cable Cleats & Hangers


Thorne & Derrick | Distributors for Ellis Patents | Cleats | Supports | Hooks | Hangers


Cable Support Requirement

Ellis were approached by a customer to supply cable hangers and bespoke cable supports for a rail project. Cable hangers are standard products for Ellis Patents and we carry a wide range in stock. We can also offer bespoke solutions which are designed and fabricated entirely in the UK. On this occasion the requirement was a little different, the cable hangers were required to be affixed to a tunnel lining in a rail tunnel using a non-standard mounting. Usually, the team at Ellis would travel to site to size up the fitment details and ensure that they had fully understood the requirement, this would include hanger loadings, location, installation considerations etc. Due to restrictions in place because of Covid, this was not possible. The customer took photographs and provided measurements. Ellis then developed a bespoke cable supports product around this specification with consideration taken into account for the ā€œunknown unknownsā€ to ensure a perfect fit on site and a product that was fit for purpose. FEA was used to check the strength of the hangers prior to production drawings being released.


Bespoke Cable Supports

Ellis Patents Solution

Ellis used their 3D CAD design capability to create a design. The strength of the product was then checked with FEA and hand calculations. Once this was complete manufacturing drawings were released to the production team at Ellis who then used their plasma cutter to create prototypes on a very short timescale. These were tested at Ellis on site test facility to validate the strength and the prototypes were supplied to the customer for a trial fitment. This went well and Ellis proceeded to manufacture the full quantity of hangers.
