SynShield® – Copper & Aluminium Foils SynShield® Type 3

Copper foil fully covered with SynTherm® insulating material - with overlay.

SynShield® copper conductor is a flexible copper foil laminated with various insulating materials.

SynShield® is just perfect for winding. There are two production methods for SynShield®:

  • The insulation is applied during a special process without adhesive. Thsi process guarantees excellent soldering behaviour and a low total strength.
  • The insulation is applied with the aid of an adhesive.


  • without soldering gap
  • types without adhesive: PET films
  • types with adhesive (SynTape®):
    PET films
    aramid papers
    PI films

SynShield Type 3


SynShield® is mainly used in transformers and can be applied as electromagnetic or electrostatic shielding between the primary and secondary winding. SynShield® is also used as a replacement for enamelled copper wires.


  • Thermal class, B, F, H (depending on insulation)
  • UL-file-no. E301705 (only SynShield® with PET)

Delivery forms
