Professional Industry Terminology

  • Silicone Rubber Insulation: Provides excellent thermal stability and remains flexible at cryogenic temperatures down to -60°C (-76°F). It is highly resistant to UV, ozone, and harsh environmental aging.
  • High-Flexibility Stranding: The conductor uses multiple fine strands of tinned copper to ensure maximum bend radius performance, making it ideal for the complex routing required in energy storage cabinets.
  • Tinned Copper (TC): Offers superior conductivity while adding a protective layer against corrosion and oxidation, especially important for high-humidity battery environments.
  • 1000V AC Rating: Specifically engineered for high-voltage energy storage systems where standard 600V cables may not provide sufficient safety margins.
  • Flame Retardancy: Complies with horizontal and vertical flame tests, ensuring safety in critical infrastructure applications.
