3M ThermaVolt® Calendered Inorganic Insulating Paper Roll, 5 Mil x 37" x 650 yd Catalog 

Features :

  • The inorganic content in ThermaVolt papers offers excellent thermal and dielectric stability, as well as long-term voltage endurance and low moisture absorption
  • The calendering process yields a densified paper with high dielectric breakdown resistance and excellent thermal conductivity
  • ThermaVolt TVF and TVFTV laminates are compatible with most commonly used impregnating varnishes and resins, and are easily impregnated, further enhancing thermal conductivity and coil bonding characteristics.
  • These are thicker constructions of ThermaVolt papers
  • Tensile Strength: 31 lb/Inch (MD), 16 lb/Inch (CD)

Applications :

  • Ground and Layer Insulation in Dry-type Transformers
  • Interwinding Insulation in Strip-Wound Coils and Electromagnet Coils
  • Spiral-Wound Core Tubes
