400kV Water Cooled Cable Repair

CCI were engaged by the National Grid to act as power cable consultants to provide engineering support for the repair of a 400kV indirect pipe water cooled low pressure fluid filled cable system feeding into the business district of London .

As a part of a the repair team and providing specialist knowledge on water cooled cable systems, CCI contributed engineering design assurance to the repair solution which was located in a tow path alongside a canal in east London. This repair necessitated modification to the canal wall and insertion of a joint into a very narrow tow path opening.

The photograph shows the early stages of the project where a cofferdam was installed to allow the existing canal wall to be dismantled prior to the repair.
