Description
- Armoured
- With lead cover (Type 3)
- Individual & Overall Screen (IOS)
- Aliphatic and aromatic hydrocarbons resistant
Standards
International : IEC 60331; IEC 60332-3-22 Cat.ADescription
Applications
These instrumentation and communication cables are used to transmit analogue or digital signals in measurement and process control. They are well adapted to underground use in industrial applications, in moist areas, where hydrocarbon and mechanical protection are needed. The lead cover brings an enhanced resistance to aromatics hydrocarbons. The individual screening of each pair limits the consequence of crosstalk. They maintain circuit integrity when exposed to fire.
