We also offer:
- Supply and manufacture of premium high voltage coils and auxiliary winding kits
- Specialist electro mechanical engineering support
- AutoCoil computer aided design, performance upgrade and reverse engineering capabilities
- Worldwide in situ support services
We currently export to over 23 countries worldwide, including Canada, Greece, Hong Kong, Indonesia, Australia, Nigeria, Norway, Venezuela, Malaysia, the Middle East, the USA and the Caribbean.
Customers are kept up to date using our Houghton Exchange video communication technology which offers live work in progress updates, visual diagnostic reports and live test results via video link to all them to keep track of their HT coils wherever they are in the world.
All full data quotes are presented using our new AutoCoil design software, utilising the latest technology to offer 3D coil design and slot build drawings for improved design and accurate fit.
Using our extensive manufacturing expertise ,we have developed a comprehensive range of insulation systems suitable for all applications, including;
- HiFLEX™ Our innovative, fully tested, totally flexible, insulation system.
- HiRES™ Our B-stage end winding solution
- HiBRID™ Our unique insulation system combining the merits of Vacuum Pressure Impregnation (VPI) and resin rich technology
- HiVAX™ Our VPI insulation system
We have been manufacturing coils for over 30 years and our skilled engineers are experts in high voltage coils and their applications. Our guide to what makes a premium high voltage coil gives further information on what to look out for when choosing a supplier.
See our guide to selecting your high voltage coil insulation system for further advice on which insulation type is most suited to your project.
We manufacture high tension coils up to 15kV with the capability for diamond coils up to 6.4 meters (21ft) in length knuckle to knuckle, 4.5 meters (14.10ft) slot pressing capabilities and a span of 1.82 meters (6ft).
We are also experienced in the manufacture of half bar systems, which are used in the winding of turbo generator machines up to 70 MW.
We pride ourselves on our attention to detail, providing a high quality product and the highest level of customer service. We understand the needs of repairers, OEMs and their customers because we are also repairers ourselves. We keep our customers updated through on-going dialogue and reporting. Through our specialist skilled staff we provide a personal, focused, fast and efficient, customer needs-driven service. We deliver on time and to budget, using our expertise to deliver effective solutions.
Our state of the art manufacturing facility comprises of a comprehensive range of automated shaping machines and electrically heated hydraulic presses.
Through a team of specialist pre-formed winding technicians we are also able to support our customers by carrying out rewinding projects in their facilities or on-site on a global basis.
We also have facilities for in-house testing; lamination, turn to turn, tan-delta and tip up and hi-pot.
Our quality assurance model, accredited to ISO 9001:2008, is designed around the requirements of each individual type of coil, meaning we create a dedicated quality management system bespoke to each individual product. This process consistently produces industry-leading insulation systems.
We listen to our customers and provide the expertise and knowledge to tailor the optimum solution for their application. That’s why our customers keep coming back to us.
We work with customers to solve their electro mechanical issues and are constantly developing our offering in line with market requirements. Should you have any requirements that you would like us to look at please don’t hesitate to get in touch
