  • • Corrosion & Protection Technology
    • Haesco offers a specialist corrosion, abrasion chemical resistant ceramic coating. The coating is an alumina oxide based technology originally developed for highly corrosive marine environments. The nature of the ceramic coating also provides high levels of electrical resistance similar to that found in porcelain insulators. The coating can be applied under normal room conditions by a number of different application techniques depending on the coating thickness and application area required.
  • • Commissioning Services
    • We can supply commissioning resource with appropriate authorisations for Power Stations, Distribution Network Operators and transmission companies for all Substation works (220V to 400kV). In addition we have a range of test equipment and injection sets available for rental.
  • • Earthing Services
    • All types of copper earth mat installation and diversion including the use of National Grid's National Safety Instruction – 24 specialist bridging equipment. These include copper to copper brazed jointing, bolted connections and protection against corrosion for dissimilar metals (typically by use of Fryolux solder paint). Haesco can also undertake installation of earth rods plus exothermic welding capabilities such as tape to rod jointing and stranded conductor to rod jointing.
