Power Distribution

Wind turbines, electric trains and hybrid cars have one thing in common: Electric power has to be distributed safely from point A to B by using laminated busbars. GTS has a broad range of materials for the insulation of power conductors.


Case Studies

  • Project Target: With continuing advances in power distribution technologies, such as the use of higher frequency power modules, there is an ever-increasing demand for high quality, high temperature insulations. In response to this and in discussion with our customers, GTS Flexible Materials Ltd has instigated a ‘High-Temperature Bus-Bar’ project, specifically aimed at the development of high temperature adhesive systems, insulation tapes and product lines.

  • Project Set-up: There was an initial identification of suitable films for use through the project, based on GTS’ extensive knowledge of their behaviour, plus a review of availability and cost. Adhesive types previously tested for high temperature were examined and selected for evaluation.

  • Project Execution: A design of experiments program was set up, testing for functionality such as temperature and humidity ageing, plus flammability and chemical resistance. Bonding trials simulating customer lamination processes were also carried out.

  • Project Result: The first in this series of High-Temperature Bus-Bar systems was a modified Epoxy adhesive with an operating temperature of 125°C.The adhesive is flame-retardant, RoHS compliant and Antimony-free. The insulation product suitable for laminated bus-bars uses a low-oligomer Polyester film, which itself is rated at 125°C
