TRATOS® C-TRI-RATED – Tri Rated cable

Tri-rated cables are a popular for use as fixed internal wiring in instrument panels and switchgear. Suitable for all fixed wiring switchboard/control panel applications where limited movement or infrequent flexing in service is required.

Manufactured in Great Britain in accordance with Standards produced by three Internationally recognised Standards bodies ensures wide acceptance and use. The flexible conductors of TRATOS® TRI-RATED are suitable for most applications allowing a significant reduction in installation time due to pliability and ease of handling when placing or dressing individual or bunches of wires. The robust PVC insulation used by Tratos on both types ensures outstanding flexibility and protection.

On temperature rating, BS 6231 states Types CK cables, once installed, are suitable for a limited degree of movement at a minimum ambient temperature of -15 °C. They are suitable for use where the conductor temperature does not exceed the designated temperature of 90o °C. (Note: However, adjacent to high-temperature zones, Tri Rated cables, which are not subject to flexing or other mechanical stresses, are suitable for 15 000 h of cumulative operation at a temperature of  105 °C provided that the direct contact temperature does not exceed 85 °C). Rated by UL and CSA at 105 °C.

In the event of a fire, PVC is self-extinguishing and does not sustain combustion, being tested to BS EN 60332-1 or 2, VW-1 and FT-1.

An alternative to this cable is the Tratos C Tri-rated Superflexible® This type of tri-rated cable is a popular choice for use as fixed internal wiring in confined spaces. 

Both of these cables are Made in Britain.
