Brand

Firewall® SR

Description


Firewall® SR Thermocouple Extension Cable is a silicone rubber insulated construction specifically designed for high temperature applications within nuclear generating facilities. It is intended for use in harsh and demanding environments where temperature extremes preclude the use of standard cables. It may be installed in trays, ducts, conduits or in confined spaces such as equipment housings. Designed for use on circuits where shielding from external electrostatic interference is required but shielding between pairs is not critical. (NU11_B)

Features


- Nuclear qualified with a minimum 40-year thermal life expectancy at 125°C

- Radiation resistant (up to 200 megarads)

- Extremely flame retardant

- Extremely flexible for installation ease

- Excellent circuit integrity during flame conditions

- Full traceability

- Easy strippability for termination ease

- All singles pass a wet dielectric (tank) test prior to braid covering to verify electrical integrity

- All cables have printed sequential footage markers for improved inventory control
