11kV systems
Senior authorised person for 11kV isolation and issue of permits on existing installations.
HV Electrical Installation
High voltage, handled with authority.
Isolation and permits, cable jointing and pulling, and transformer oil analysis and treatment on site.
Experience gained over many years dealing with HV installations allows us to offer the following services.
Cable jointing
We provide cable jointing services for all types of cable technologies. We operate on LV and HV systems and stock a wide range of joints, enabling us to offer a rapid response.
Cable pulling and laying
We install cables in trenches, ducts or on ladder racking systems for both new and existing installations. All forms of civil works can be accommodated, including new ductwork and concrete plinths.
- Multicore XLPE SWA or LSF
- 16 to 400mm
- Single core cables
- 50 to 1000mm
Transformer oil analysis
We provide a comprehensive solution for all aspects of high voltage insulating oil analysis and filtration treatment.
Our mobile oil treatment plant can be brought to site to restore the transformer oil to specification. Most transformers can be treated whilst still on load, minimising downtime and disruption.
When needed, normally due to high acidity levels or PCB contamination, we offer an insulating oil replacement service, with empty drums for waste oil that is removed from site. We ensure that the Environment Agency documentation for safe disposal of oil is issued.
