EN 50288-7 Mica tape/XLPE insulation IOS Unarmoured Fire resistant
Description
- Instrumentation cables 170/300 V
- Individual & Overall Screen (IOS)
- Oil resistant
Description
- Individual & Overall Screen (IOS)
- Oil resistant
Standards
International : IEC 60331; IEC 60332-3-22 Cat.ADescription
Applications
These instrumentation and communication cable are used to transmit analogue or digital signals in measurement and process control where chemicals may be present. The individual screening of each pair limits the consequence of crosstalk. They maintain circuit integrity when exposed to fire.
