Description
When it comes to electrical safety and system longevity, compromise isn’t an option. Our Fibreglass tape is specifically designed for professionals who require a high-tensile, heat-resistant barrier for critical electrical components. Unlike standard PVC tapes that melt or degrade, this fiberglass cloth insulation tape maintains its structural integrity even under constant thermal stress.
Crafted from high-quality alkali-free glass fiber, this tape is the preferred choice for transformer winding and motor armatures. Whether you are looking for a self adhesive fibreglass tape for quick positioning or a non-adhesive variant for traditional dry-wrapping, our 5Mils series offers the perfect balance of flexibility and ruggedness.
Why Engineers Prefer Our Fiberglass Tape:
-
Extreme Heat Resistance: Capable of withstanding Class F and Class H temperatures, making it ideal for high-voltage transformers.
-
High Dielectric Strength: Provides excellent insulation properties to prevent arcing and short circuits in tightly wound coils.
-
Tensile Superiority: High mechanical strength ensures that windings remain tight and secure, even under the physical vibrations of a running motor.
-
Non-Corrosive: Chemically inert material that won’t react with varnishes or impregnating resins.
