Denso’s Long-life Protection for Electricity Pylons

Posted: Tuesday 10th August 2010

Northern Divers Engineers Ltd of Hull has recently completed a contract for protecting the leg bases of electricity pylons in a Midlands Area of Special Scientific Interest (SSI). The consultants for the project, Intertek Ltd, recommended a Winn & Coales Denso Tape system.

Denso Tape had been applied 25 year ago to protect the pylon leg bases and when it was removed by Northern Divers, using hand tools, the surfaces were found to be still free from corrosion.

The new Denso Tape system was applied partially immersed from the concrete base up to 2 metres of the pylon legs. It comprised application of Denso paste, Denso Profiling Mastic to give smooth contours for the two following tapes. These were Denso Marine Piling Tape followed by Denso Glass Outerwrap. This is expected to give full protection for at least another 25 years.
