| EN 50288-7 Multi Pair, Overall Screened, Steel Braid Armoured Instrumentation Cables 300 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. With Steel Braided over the cable, the cable also provides added flexibility to protect against mechanical impacts. Furthermore, these cables can directly be buried in the soil. They are suitable in dry and wet indoor and outdoor installations. |
