3M 1276 Paper/Glass Filament Electrical Tape, 5/8" x 60 yd x 9 Mil, White

ID: 3M1276X.625 Mfr ID: 1276X.625
Manufactured by: 3M Electrical OEM Materials
Filament tapes are designed for applications needing both the dielectric strength of polyester film and high mechanical strength of glass fibers. They offer the ultimate in low strength, high tensile and edge-tear resistance for a more cost-effective solution to glass cloth tapes. 3M Electrical Tape 1276 is made of an electrical-grade paper backing, reinforced with parallel glass filaments and an oil-compatible acrylic pressure-sensitive adhesive.

3M filament reinforced electrical tape 1276 is a 9 Mil glass filament-reinforced paper backing with high-shear strength acrylic adhesive. Solvent-resistant, it offers good tensile strength for holding in oil-transformer applications. Unlike conventional film-backed tapes, this products’ paper backing construction provides for complete impregnation and saturation of the tape in adjacent layers of insulation.

3M 1276 Paper/Glass Filament Electrical Tape, 5/8" x 60 yd x 9 Mil, White Technical Data Sheet 

Features :

  • Stable adhesive even after long exposure to transformer fluids
  • Saturable backing for air entrapment resistance
  • Minimal air trapped between adhesive layers in tape
  • Minimum contamination of oil power factor and interfacial tension
  • Stiffness for excellent handling, which promotes operator efficiency during application of the tape during coil winding operations
  • Diamond paper insulation thermal bonding compatibility with back side of tape
  • Excellent for anchoring lead wires to banding coils and end turn taping

Applications :

  • For Holding in Oil-Filled Transformer
