Jointing up to 400kV

Leaders in High Voltage Solutions – Expertise, Safety, Quality

Our electrical engineering expertise has brought many innovative solutions to the challenges that face the energy sector. Our highly experienced multi-skilled teams specialise in extra-high-voltage up to 400kV and fibre optic cable installation.

All H&Askham personnel are highly qualified. We have specialists in voltages up to 400kV, in polymeric, fluid-filled and transition joint products. We have extensive knowledge of a range of systems, including ABB, Prysmian, NKT, Nexans, WT Henley & Pfisterer, and also have the capabilities to undertake work on older BICC Cables and fluid-filled products.

Our HV experts are qualified and trained on systems and products with voltages from 11kV – 400kV, and fibre optic splicing on a variety of products, for various applications. We are currently constructing a 400kV substation with principal contractor Linxon, that will eventually plug power from Hinkley Point C to the National Grid, powering millions of UK homes and businesses – we are committed to a low carbon future.
