High-Performance Electrical Insulation Tapes | Harnawa Insulations
Precision Protection for High-Temperature Environments
In the electrical industry, heat isn’t just a byproduct—it’s a challenge. Without the right insulation, even the best-designed systems fail.
At Harnawa Insulations, we manufacture a specialized range of high-temperature electrical tapes engineered to withstand extreme thermal stress, chemical exposure, and high-voltage demands.
Whether you are winding a transformer or insulating a motor, our tapes provide the ultimate safety barrier.
Why Engineers Choose Harnawa Tapes
Most standard tapes fail when temperatures climb. Our products are categorized by thermal class, ensuring you remain compliant with global safety standards:
-
Reliable Dielectric Strength: High breakdown voltage ratings up to 14,000V.
-
Superior Adhesion: Advanced Acrylic and Silicone adhesive systems.
-
Thermal Stability: Solutions ranging from Class B (130°C) to Class H (180°C).
-
Mechanical Integrity: Excellent tensile strength and puncture resistance.

Our Core Product Line
Aramid Paper Adhesive Tapes – ‘H’ Class
Designed for the most demanding thermal environments. Utilizing 2-mil Nomex® paper, these tapes offer high tensile strength and are the industry standard for Class H motor and transformer insulation.
Polyimide (Kapton®) High-Temp Tapes
The ultimate solution for high-voltage protection. With a staggering breakdown voltage of 14,000 Volts in our 3-mil variant, these tapes remain stable where others melt.
Fiberglass & Glass Cloth Tapes
Available with both Acrylic and Silicone adhesives. These are essential for applications requiring immense mechanical strength and resistance to tearing or abrasion.
Polyester Electrical Tapes
Our most versatile range. Available in clear and colored variants, these offer 60% elongation, allowing them to conform perfectly to complex shapes and uneven wiring.
Specialized Filament & Woven Tapes
For heavy-duty industrial needs, our Polyester Fiberglass Filament Tapes and Polyester Woven Tapes provide the structural reinforcement and resin absorption required for potting and casting.
