Case Study

Higher reliability at a lower cost

When a global engineering leader was contracted to refurbish several high voltage substations in Iraq, TE supported them with a gas-filled bushing solution that delivered reliability, availability and safety – with dramatic cost efficiencies.


A large multi-national company supplying a complete high voltage substations to high voltage power transmission and power distribution companies had secured the contract to refurbish serveral high voltage substations in Iraq.


  • New solution to meet the supplier’s technical requirements
  • Solution to operate in extreme conditions at a dramatically reduced price point
  • Development to delivery was required within 16 weeks


  • A gas-filled bushing that has been qualified for standard applications since 2009
  • Qualification consisted of an extenstive design and test program
  • Bushing assembly done at TE Connectivity (TE) in switzerland and final assembly with tests in Berlin
