New Wear Bridge Crossing

Northern Power Grid installed power cables under the New Wear Bridge as a new main supply route. The existing route on the Queen Alexander Bridge was scheduled to be decommissioned due to its age and the phasing out of oil filled cables. The cable installation is unique in that it requires the cables to be suspended under the bridge and above a river. The cables are carried in Emtelle ducts.

Balfour Beatty were contracted by NPG to install the cables, they in turn approached Ellis to provide a cable duct support solution.

Cable Duct Support System

Ellis Patents Solution

Ellis worked with Balfour Beatty to develop a product to suspend the duct from the underside of the bridge, and also develop an installation methodology. The solution was based around on 12 off standard 2F+ clamp with a bespoke stainless steel structure.

240 assemblies in total were supplied. The frames hang from the underside of the bridge and support ducts supplied by Emtelle. Power cables are then installed into these ducts.

Taishan Nuclear Power Project

The Taishan Nuclear Power Project is a joint venture between EDF and China Guangdong Nuclear Power Group, it is the second nuclear power station to be built using Areva’s 1,750 megawatt EPR and it is the second time Areva has used Ellis Patent’s products to secure electrical cables at a nuclear plant.

Our first specification for Areva was for its OL3 reactor in Finland in 2009, and was secured as a result of our proven technical expertise and excellent industrial references.

Emperor & ProTect Cable Cleats

Ellis Patents Solution

Emperor Cable Cleat

The Emperor Cable Cleat is designed for use where the highest levels of short circuit withstand are required, Ellis’ Emperor cable cleats are available for both trefoil and single cable applications. All products in the range are manufactured in type 316L stainless steel, meaning they provide ultimate corrosion protection, even in the harshest of environments.

The benefits of the Emperor cleats also extend to a patented design, which makes installation quick and easy, and an integral LSF zero halogen polymeric liner and base pad that protects and cushions cables during short circuit.

ProTect Cable Strap

Ellis’ ProTect cable straps, which are manufactured out of 316L stainless steel, are designed for installation between trefoil cleats, such as Emperors. They not only enhance short circuit capabilities, but help to retain trefoil formation and, because they allow for greater fixing distances between cleats, can reduce installation time and cost.

Pre-Commissioning LV HV Systems by Oakes Power Services Ltd

by Daniel Oakes | Managing Director | Oakes Power Services Lts

uploaded by Chris Dodds | Sales & Marketing Manager at Thorne & Derrick 

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.

Trefoil Cable Cleat | UKPN London Power Tunnel

UKPN London Power Tunnel

The London Power Tunnels project will create a new 32km electricity super highway deep below the capital, which will help keep Londoners connected to safe and reliable electricity supplies. In some areas of the system power is transmitted via 6 sets of cables in trefoil arrangement, to safely contain these cables a new trefoil cable cleat was required.

Trefoil Cable Cleat

Ellis Patents Solution

Working directly with UK Power Networks (UKPN), Ellis Patents developed a trefoil version of its Centaur cable saddle, a bespoke product that not only allowed the preferred trefoil arrangement of HV cables to be run through a stretch of tunnel between New Cross and Finsbury Market, but also significantly reduce the number of supports required. An essential part of the development process was a product test in a short circuit test station in Prague. For the test the structure used in the tunnel was created and suitable cable shipped from the UK.
