HC Technical are approved contractors for the National Grid. We can carry out / specify a variety of repairs to resolve common issues such as transformer leaks and damaged porcelain sheds. None of our solutions involve hot works and require no specialist tools. We can provide a fast, safe and reliable solution to reduce downtime and associated plant replacement costs.
Please see above for our most recent project for the National Grid repairing a damaged porcelain shed. The simple repair involved taking a mold from an undamaged part of the conductor with paste elastomer before using a repair compound to reform the shed and then coating it to match the colour and prevent any arcing across the repair.
Another common issue in power generation and distribution is transformer and SF6 leaks. The video below demonstrates how easy, cost effective and safe it is to repair these leaks using the Belzona products.
