Description


Firewall® III-Unipass is a one conductor, unjacketed, nuclear Class 1E power cable. Its tough thermoset construction allows for its use in demanding applications without additional jacketing protection. It is intended to perform low voltage power and lighting functions and may be installed in trays, ducts, conduits or directly buried.** (NU06_D)

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

- Reduced size and weight for increased raceway capacity

- Easy strippability for installation ease

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