Woven Fiberglass Insulation Tape

High-Performance Woven Fiberglass Insulation Tape (Class F 155°C)

Our Woven Fiberglass Insulation Tape is manufactured using superior non-alkali glass fiber yarn, tightly woven to deliver outstanding mechanical strength, chemical stability, and heat resistance. Rated for Class F (155°C) operating conditions, this non-adhesive woven glass webbing tape serves as a reliable binding and insulation layer for power transformers, distribution transformers, electric motors, and high-voltage generators.

Designed to perform in demanding industrial environments, the woven structure allows deep impregnation of insulating varnishes and transformer oils, creating a seamless, moisture-resistant protective barrier around copper and aluminum windings.

Key Features & Technical Advantages

• High Thermal Endurance: Withstands continuous operating temperatures up to 155°C (Class F) without deteriorating, snapping, or losing structural integrity.
• Superior Tensile Strength: Tightly woven fibers resist stretching and mechanical tear during high-tension manual or automated winding processes.
• Excellent Varnish & Oil Absorption: The porous, untreated fibrous surface easily absorbs transformer insulation oil and insulating varnish for complete void-free dielectric protection.
• Alkali-Free Glass Fiber: Manufactured from non-alkali E-glass, preventing chemical degradation, corrosion, and electrical tracking over time.
• Dimensionally Stable: Non-shrinking material that maintains exact thickness and tension under extreme electrical and thermal loads.

Applications in Bangladesh Electrical Industry

• Transformer Manufacturing & Repair: Used for winding insulation, core binding, layer wrapping, and lead anchoring in power and distribution transformers.
• Electric Motor Rewinding: Ideal for slot insulation, end-turn binding, and coil bundling in AC/DC industrial motors.
• Switchgear & Control Panels: Applied as flame-retardant binding and phase insulation in high-voltage panels.
• Coil & Generator Insulation: Serves as a primary wrap prior to vacuum pressure impregnation (VPI).
