Description

Description

Standards

  • Product
    IEC 60228
  • Test
    IEC 60332-3-22 Cat.A; IEC 60754; IEC 61034

Applications

These cables are intended for transmission of analogue and digital signals. They allow transmission over long distances at high pulse rates. These cables are used in industrial installations (refineries, chemical plants, etc...) where there is a potential risk of mechanical damage.
