Mobile transformers are used in mobile substations. These substations are used in emergency situations or as temporary solutions for the supply of electric power. Mobile transformers are very compact due to the application of special insulation techniques such as the application of Nomex® insulation. Units are available either with conventional, hybrid or Nomex® insulation.
The use of Nomex® insulation allows higher temperatures, which in combination with oil to air coolers result in extremely compact transformer designs.
