Applications

Harsh Environment Power Control Instrumentation

Description


RSCC’s Firewall® LSHF instrumentation cable is a completely thermoset construction specifically designed for low smoke halogen free applications in utility generating plants and substations. It is intended for use in harsh and demanding environments, including Class 1E nuclear applications. It may be installed in trays, ducts, conduits or in direct burial applications to perform a variety of signaling and related functions. Designed for use on critical circuits where complete isolation is required between pairs and from external interference. (NU19_A)

Features


- Complete Low Smoke Halogen Free (LSHF) Insulation and Jacket

- Thermoset insulation and jacket for enhanced thermal stability

- Extremely flame retardant

- Nuclear qualified with a minimum 60-year thermal life expectancy at 90°C

- Radiation resistant (up to 90 megarads)
