Number 1339, Filament Reinforced Electrical Tape


Filament Reinforced Electrical Tape

larger image
Many of the 3M™ Filament Tapes were designed for applications needing both the dielectric strength of polyester film and the high mechanical strength of glass fiber.

Offering the ultimate in low stretch, high tensile strength and edge-tear resistance, these products are more cost effective than glass cloth tapes in applications up to 130 °C. They can be used to anchor lead wires and terminal strips and to band coils. A special paper-backed filament tape is also available to meet the unique requirements of high voltage oil-filled distribution transformers. Available in custom widths from 1/8 inch to 24 inch, and comes standard on a 60 yard roll on a 3 inch diameter core. Standard length varies by thickness.
