Power distribution cable systems
We’re experts in power distribution, working with DNOs, IDNOs and power contractor supplying power distribution cables and components across the UK and Ireland.
Adapting to change
As the power distribution market grows its focus on renewable energy and smart technology, we’re continuing to work with the UK’s seven DNOs and 13 licensed IDNOs to support with power distribution cable systems and help future-proof cable networks.
Meeting national demand
Power distribution is the final, critical stage in the delivery of electricity to residential commercial and industrial users. This goes beyond turning on appliances – the safe, reliable and efficient distribution of electricity helps to support economic activity, drive growth and maintain social progress and wellbeing.
Having the correct infrastructure across power distribution networks helps to minimise outages and reduce downtime, whilst also ensuring safety and enabling access to new power sources.
The experience to tackle your cable systems challenges
Our power distribution cables and technical expertise span the primary power distribution network, including 132kV and 66kV cable networks from grid supply points, as well as the 33kV and 11kV underground cable networks needed to reach industrial, commercial and domestic end users.
Market-leading cables
A carefully-selected range of best-in-class cables held in stock, including Low Voltage 1kV//3kV, Medium Voltage 33kV, High Voltage 132kV and Extra High Voltage 275kV/400kV.
High-quality accessories
