Applications

Harsh Environment Power Control Instrumentation

Description


Firewall® SIS is a one conductor, unjacketed, nuclear Class 1E Switchboard Wire. Its tough thermoset construction allows for its use in demanding applications without additional jacketing protection. It is intended for low voltage applications and may be installed in switchboards, panel boards or other electrical apparatus where superior performance is required. (NU07)

Features


- Thermoset insulation and jacket for enhanced thermal stability

- Specially formulated insulation for superior long term water resistance

- Extremely flame retardant

- Nuclear qualified with a minimum 40-year thermal life expectancy at 90°C

- Radiation resistant (up to 200 megarads)

- Full traceability

- Excellent mechanical properties

- Tin-coated copper conductors for improved terminations and corrosion resistance

- All cables pass a wet dielectric (tank) test to verify insulation integrity

- Easy strippability for installation ease

- Low surface coefficient of friction insures installation ease with reduced pulling tension required
