High-Voltage Underground Network

Underground power, laid, tested and brought into service.

Laying, testing and commissioning of 11 kV / 22 kV HT underground network infrastructure for projects where reliable high-voltage distribution needs to run below ground.

11 kV / 22 kV HT Network

Underground distribution with a complete project scope.

Underground HT networks require more than cable placement. Route conditions, cable handling, jointing and terminations, testing and commissioning all form part of bringing the network into service.

The exact method and equipment depend on the approved project design, cable specification and site conditions. Our service is presented around the complete laying, testing and commissioning scope.

Project-specific requirements matter. Cable type, route, jointing arrangement and testing regime should be confirmed from the approved project documents.
