Electrocube, design manufacturer of electronic components

Foil Transformers

High frequency, aluminum foil, copper foil, foil winding

Electrocube designs and manufactures hundreds of transformers and inductors using aluminum foil or copper foil in place of the standard copper wire used in conventional coil wire-wound transformers. This unique construction technology was first introduced to the aerospace industry by the transformer design manufacturer in the 1960s.

What types of transformers does Electrocube manufacture and distribute?

Hundreds of Electrocube electrical component designs are available, including specific, qualified designs as OEM or replacement parts for all major commercial aircraft and jetliners, military and defense aircraft as well as many land-based facilities. The efficiency of these transformers exceeds 95% with regulations of 2% to 5%.

  • Aluminum foil transformers
  • Copper foil transformers
  • Foil winding transformers
  • High frequency transformers

How do foil transformer designs work?

Basic construction consists of electrical grade aluminum or copper foil, temperature-suitable interwinding insulation, fiberglass and nomex sheet insulation. The unit is then vacuum pressure impregnated (VPI) with a specially formulated epoxy resin designed to assist in heat transfer and to bond the components into a stable, dense unit.

Produced as isolation transformers or autotransformers in all standard mechanical configurations (open frame or enclosed), foil transformers operate within single phase current or multiphase current parameters of:

  • Frequency: 300 Hz to 10 KHz
  • Power: 25 VA to 50 KVA and up
  • Voltage: Fractional volts 110 to 600V (higher voltages over 600V available)
  • Temperature: -50°C to 250°C ambient (fully rated)
