Nexans CSA unarmoured tray cables are CSA certified as type CIC in accordance with CSA C22.2 No. 239 (Control and Instrumentation Cables), and type TC in accordance with CSA C22.2 No. 230 (Tray Cables). They are suitable for installation in cable tray, raceway (such as conduit), or direct burial in industrial applications. The minimum recommended installation temperature is minus 40°C (with suitable handling procedures). All cables are marked sunlight resistant, direct burial, FT1 and FT4, making them suitable for a wide range of indoor and outdoor installations.
- For use in raceways (conduit, and ventilated, non-ventilated, and ladder-type cable trays) in dry or wet locations and where exposed to weather. Nexans cables are marked “SUN RES” for sunlight resistant.
- For direct earth burial (with protection as required by the Inspection Authority).
- For direct embedding in concrete, masonry or plaster (with permission as required by the local Inspection Authority).
- For use in ceiling air-handling plenums.
- Minimum recommended installation temperature minus 40°C (with suitable handling procedures).
- Maximum conductor temperature 90°C.
- Rated 600 V.
- Pulp and paper, chemical, petroleum and other primary and secondary manufacturing industries.
- Utility generating and switching stations as control or supply cables.

Docs and info
In case of fire, well maintained early warning smoke detectors will give an alarm long before non-metallic coverings become combustible.
However, in spite of the widespread and long-standing use of PVC in residential and commercial buildings, all purchasers of PVC insulated / jacketed products should be aware of the following:
· Non-metallic coverings of electrical cables can burn and may transmit fire when ignited.
· Burning non-metallic coverings may emit acid gases which are toxic and may generate dense smoke.
· Emission of acid gases may corrode metal in the vicinity; e.g. sensitive instruments and reinforcing rods in cement.
