Mica tape for fireproof cables

Mica tape for fireproof cables

Mica tape for fireproof cable is mainly used for the fire-resistant layers in fireproof cables. It is made of mica paper and reinforcements bonded with silicone adhesive which has excellent resistance to heat. Also, the OMF-8 has obtained the UL94 V-0 standard. (UL File No.E58537)

Characteristics

  1. (1) Excellent electrical properties under high temperature conditions.
  2. (2) Uniform thicknesses and properties.
  3. (3) Highly flexible and easy to wind, which provides good adhesion with conductors.
  4. (4) DG88-AN is easy to work with, as it contains adhesive on one side.

Use

  1. (1) Fireproof cables
  2. (2) Connection of fireproof cables
  3. (3) H-class dry type transformers
  4. (4) Insulation of highly heated parts of soldering iron, etc.
  5. (5) Insulation of highly heated parts
