Underground cables
High voltage, HV cable installation & route design
Providing HV cable installation and design services across the UK. Our cable engineers can undertake all aspects of cable installation and route design, from early planning and investigation to cable pulling calculations and project management of cable laying activities. Previous installation projects range from small fault repairs to a full HV cable replacement route, across varying installations through inner city, urban and rural landscapes, incorporating a wide range of ‘Areas of Engineering Difficulty’ (AED’s).
EDES has a vast level of experience and knowledge in the delivery of Overhead Line (OHL) design and consultancy support to all UK DNOs. EDES’s management legacy as Senior Authorised Persons provides our engineers with an advanced understanding of the operational aspect of HV & EHV systems.
