6491B Conduit Wiring Cable

Application and Description :

  • 6491B is equivalent to harmonized code H07Z-R, these cables are designed for fixed wiring purposes in domestic and industrial power/lighting applications. Can be used in trunking or conduit, or may be surface mounted when used for earthing. and generally in areas (such as public and government buildings) where smoke and toxic fumes may cause a threat to life and equipment. The cables produce no corrosive gasses when burnt which is particularly important where electronic equipment is installed.

  • - Fine bare copper strands


    - Strands to IEC 60228 Cl-2


    - Thermosetting core insulation type EI5


    - LSOH - low smoke, zero halogen

Insulation Colour :

  • Black, Blue, Green/Yellow, Red, Yellow, White, Violet, Brown, Grey, Orange, Pink

Technical Characteristics :

  • - Working voltage: 450/750v
  • - Test voltage: 2500 volts
  • - Minimum bending radius: up to 10 mm² - 3 x overall diameter, above 25 mm² - 6 x overall diameter
