Instrumentation cables silicone insulation for fossil power plant

Applications

These Instrumentation and communication are used to transmit analogue or digital signals in measurement and process control for fossil power plant. When they are armoured, they are well adapted to underground use in industrial applications where mechanical protection is needed. The individual screening of each pair limits the consequence of crosstalk. They maintain circuit integrity when exposed to fire.
