| EN 50288-7 Multi-Pair, General Screened, Instrumentation Cables300 V – 500 V |
Application
| These cables are generally employed in instrumentation and control systems, analog and digital signal transmission of chemical and petrochemical industrial premises, power plants, natural gas and petroleum industries, etc. Direct connection is not permitted under ambient with a low impedance sources. Cables with blue sheaths are suitable for security system applications. Furthermore, these cables can directly be buried in the soil. They are suitable in dry and wet indoor and outdoor installations. |
