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.

Formats:

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

SynShield Type 3

Application

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.

Standards

  • Thermal class, B, F, H (depending on insulation)
  • RoHS-compliant acc. 2011/65/EU and (EU) 2015/863
  • UL-file-no. E301705 (only SynShield® with PET)

Delivery forms

100 and 200 m rolls with 76 mm core.

Other dimensions and lengths on request.

Conductor

Copper foil of at least 99.90 % Cu and with high or even high electrical conductivity.
