KC70 Fireproof Tape: Essential Defense Against Electrical Fires in Critical Infrastructure

Electrical fires represent a severe and persistent threat within power distribution systems and these incidents can trigger cascading failures, catastrophic asset loss, and significant downtime. The KC70 Fireproof Tape, engineered by COTRAN, provides a cutting-edge, proactive solution designed specifically to mitigate this risk by preventing cable fires at their source.


Advanced Fire Suppression Technology
Unlike conventional fire-resistant tapes, KC70 employs a unique reactive mechanism. When exposed to flame, it instantly forms a robust, carbonized insulating layer. This critical barrier serves a dual purpose: it effectively blocks oxygen, starves the fire, and provides exceptional heat resistance, preventing flame spread and suppressing arc propagation. Independent testing, including rigorous 1000°C burn tests, validates its ability to contain fires under extreme conditions.

Unmatched Technical Specifications for Demanding Environments
KC70 sets a new benchmark for performance, exceeding typical industry standards:

  • Superior Fire Resistance: Achieves an outstanding oxygen index of 54.5% and passes the stringent UL94 V-0 self-extinguishing rating.
  • Exceptional Durability: Offers high tensile strength (6.1 MPa) and remarkable flexibility (510% elongation), allowing it to conform tightly to irregular cable joints and terminations without cracking.
  • Environmental Resilience: Withstands exposure to harsh elements including water, acids, alkalis, and salts, making it suitable for underground cables, marine applications, tunnels, and chemical plants.
  • Thermal Stability: Maintains reliable performance across a wide temperature range, from sub-zero conditions to high-heat scenarios.
  • Electrical Integrity: Provides high dielectric strength, ensuring critical insulation and reducing short-circuit risks even during fire events.


Seamless Installation for Critical Applications
A key advantage of KC70 is its self-fusing, self-adhesive property. It bonds securely to itself upon stretching and wrapping, eliminating the need for separate adhesives or heat tools. This simplifies installation: apply with a 50% overlap and finish with two self-fusing end loops. This ease is crucial for large-scale or complex projects. Its effectiveness makes it the first line of defense in:

  • Critical Infrastructure: Substations, power generation facilities, metro systems, and tunnels where cable failure is unacceptable.
  • High-Voltage Protection: Securing joints and terminations across low, medium, and high-voltage cables to prevent arc-induced ignition.
  • Complex Industrial Sites: Petrochemical plants, mines, and offshore installations requiring resistance to chemical corrosion alongside fireproofing.


The Imperative for Enhanced Fire Protection
As power grids age and energy demands escalate, robust fire prevention transcends mere compliance—it becomes an existential priority for utilities and industrial operators. KC70 Fireproof Tape delivers more than just fire mitigation; it actively sustains circuit integrity during emergencies, minimizing the potential for catastrophic failure and protecting vital infrastructure. For organizations committed to resilience and verified safety in power transmission and distribution, KC70 fireproof tape offers an indispensable, high-performance solution engineered for real-world extremes.
