HEIGHWAY Energy
for High Voltage Services
HEIGHWAY Ltd have successfully completed the Civils, Jointing, Connection & Commissioning package of works associated with the 33kV High Voltage Power Supply to a new build 5MW solar farm in the UK.
HEIGHWAY are a leading provider of HV Power Services to the renewable, rail, substation and energy sectors with an impressive track-record and future project pipeline following recent audit and Accreditation under the National Electricity Registration Scheme (NERS).
SOLAR FARM PROJECT NOTES
HEIGHWAY provided the following scope of works for the solar farm construction, commissioning and energisation:
- HV Cable Diversion Works
- HV Cable Installation to New Customer Substation
- HV Park Feeder & VT Connections
- Installation of 3 New Sets of CT’s
- Excavation Works to DNO Compound Including Installation of New Concrete Bases
- Installation of COP3 Metering Panels
- Full Commissioning of all Cabling, VT’s and CT’s & HV Switchgear
By George Heighway | Director at HEIGHWAY Ltd
The HV switchgear and transformers providing electrical power distribution at 33kV were connected using the Euromold brand of separable connector manufactured by Nexans – the Interface C Connectors were installed to the T Boot Station and the 33kV single core power cables were prepared, terminated and tested by our Jointers. Euromold bolted terminations are OEM approved and trusted by leading manufacturers of medium and high voltage electrical equipment including Lucy Electric, Siemens and ABB.
Reliance & Compliance
Our team of Jointers are Competent and Qualified in the installation of all types of cable joint and termination technology up to 33kV, including heat shrink and cold shrink, but the engineering preference of our HV Jointers for separable connector technology is the EPDM type manufactured by Nexans. Euromold kits are cost-competitive in the marketplace and readily available from stockists such as Thorne & Derrick, that said our focus as a business is not “lowest-cost” option. Our reputation rides on the reliability of the products we install and the expertise levels of our site teams that install them – also as a contractor we understand the criticality of accurate cable preparation using precision engineered cable tooling to achieve consistently high-quality results, for this reason our Jointing Team have standardised on tools manufactured by Alroc.
The Difference is Material
The Euromold separable connectors are manufactured from high quality EPDM which provides high mechanical strength which can be easily connected and disconnected from the equipment bushing for routine maintenance – competing silicone cable connectors have a tendency to attach and “stick” to the bushings and cannot be easily removed sometimes without damaging the actual connector. Euromold pioneered and innovated the separable connector – their products provide excellent resistance to compression, cutting, impact, tearing and abrasion over a wide temperature range.

Configuration | the Interface C type connectors provide versatile and optional system design configurations. Here, our team of Jointers were deployed to “Piggy-back” the Euromolds into the medium voltage switchgear compartment. This dual-cable installation is enabled by the use of a connecting plug to mate the front-end connector to the back-end.
Service | Should you require technical support to enable the design or specification of 33kV power cable accessories or systems please do not hesitate to contact Thorne & Derrick, the Contracted & Approved UK Distributor for Nexans Power Cable Accessories.
Sealed & Supported | The 33kV single core power cables manufactured to BS7870 Standard were sealed at the transformer point of entry using heat shrink cable sealing glands to prevent water ingress and protect against cable damage. The cables are cleated to provide mechanical retention to the cable in position and electrical short circuit protection in the event of a fault situation.
11kV Services | Here HEIGHWAY Ltd completed the HV Isolation, Installation, Test, Termination & Commissioning of new 11kV transformer tails including preparatory de-vegetation works surrounding the site location which was heavily weeded and overgrown.
