VOLSUN
The Flame Retardant Tape for Power Cables stands as an essential safety component in electrical infrastructure, engineered to slow fire propagation and maintain circuit integrity during thermal emergencies. This specialized tape combines intumescent properties with robust electrical insulation, providing a dual-layer protection system for power cables in commercial, industrial, and utility applications. Its pressure-sensitive adhesive ensures easy application to both straight runs and complex cable configurations, forming a protective barrier that expands into a heat-insulating char layer when exposed to flames—critical for preventing fire spread and extending evacuation time in emergency situations.
The tape features a specialized elastomer backing that expands significantly when exposed to high temperatures, forming a thick insulating char layer that acts as a physical barrier between flames and cable insulation . This intumescent action delays heat transfer to critical cable components, maintaining circuit integrity for extended periods during fire events. The tape achieves a UL listed flame retardancy rating, meeting stringent safety standards for electrical installations .
With a dielectric strength of 1150 V/mil, the tape provides reliable electrical insulation for cables rated up to 600V, preventing short circuits and maintaining system integrity . Its insulation resistance exceeds 10⁶ megohms, ensuring minimal leakage current in both dry and humid conditions . The tape's conformable design allows complete coverage over splices, terminations, and irregular cable shapes without compromising insulation performance.
Constructed with a 7 mil thick PVC backing and rubber-resin adhesive, the tape combines flexibility with mechanical strength . It stretches to 250% elongation for easy application around bends and connectors, then maintains constant tension to prevent loosening over time . The adhesive forms a permanent bond to most cable jackets, resisting moisture, UV radiation, and industrial chemicals for long-term performance in harsh environments.

Protects power cables in high-rise buildings, hospitals, and data centers where fire safety is critical. Ideal for sealing cable penetrations through fire-rated walls and maintaining circuit integrity in emergency power systems.
Shields cables in manufacturing plants, chemical processing facilities, and refineries where fire risks are elevated. The tape's chemical resistance ensures performance in environments with oils, solvents, and corrosive substances.
Secures and protects cables in substations, transformer yards, and renewable energy installations. Its UV resistance makes it suitable for outdoor applications including solar farms and wind energy facilities.
Provides fire protection for cables in airports, railway stations, and metro systems where rapid fire spread could have catastrophic consequences. Maintains critical power during evacuation and emergency response.
When exposed to flames, the tape's intumescent formulation expands to form a thick, insulating char layer that acts as a physical barrier between the fire and underlying cable insulation . This char layer slows heat transfer, preventing adjacent cables from igniting and delaying insulation breakdown in the protected cable.
Yes, the tape's UV-resistant formulation and weatherproof adhesive make it suitable for indoor and outdoor use . It resists degradation from sunlight, moisture, and temperature fluctuations, maintaining both fire retardant properties and adhesion in exposed outdoor installations.
No, for safety reasons, the tape should only be applied to de-energized cables. While it provides electrical insulation when properly applied, installation on live conductors creates shock hazards and may result in incomplete coverage or improper adhesion.
When stored properly and applied according to specifications, the tape maintains its fire retardant properties for 10+ years in typical indoor applications . Outdoor installations may have slightly reduced service life depending on exposure conditions, with periodic inspection recommended every 2-3 years.
