Tri-Rated Cable - BS6231 / UL758 / CSA22.2

Tri-Rated Cable Standards & Approvals

British Standard Institute - British Standard BS6231 Type CK. This standard covers single core PVC insulated flexible electrical cables of rated voltage 600/1000V for switchgear and control gear wiring.

British Standard BS6231 Type CK specifications require this high temperature cable to operate at a maximum temperature of 90^oC in continuous use, however tri rated cable has a maximum operating temperature of 105^oC in order to also comply with UL758 and CSA 22.2 No.210.

Tri-rated cable, panel wire manufactured to BS6231 Type CK, should not be confused with other cable manufactured to BS6231 Type BK which has a maximum conductor operating temperature of 70^oC.

Canadian Standards Association - CSA 22.2 This standard specifies the requirement for flexible cords, elevator cables, and hoistway cables rated to a maximum of 600V.

UL 758 This standard specifies the requirements for flexible cords, elevator cables, electric vehicle cables, and hoistway cables rated up to 600V.

Our cables are recognised to UL style:
 - UL 1015 cable size: 30 AWG - 2000 kcmil

Our Tri-Rated cable also holds BASEC approval from the British Approvals Service for Cables.

Bi-Rated Cable

As BS6231 covers sizes up to a maximum of 240mm², panel wire with a size ranging up to 500mm² which are covered under the specifications set by the CSA and UL are known as bi-rated cables.

H05V2-K / H07V2-K Cable

Our cables also meet and exceed the requirements of the harmonised cable types H05V2-K and H07V2-K.

H05Z-K / H07Z-K / 2491B / 6701B - LSZH Cable

As trirated cable is not suitable for applications requiring Low Smoke Zero Halogen (LSZH) insulation, alternative panel wire must be used. These include H05Z-K, H07Z-K, 2491B and 6701B with these panel wires generally being required for use in public areas to prevent the smoke and toxic fumes which could represent a threat to life or cause damage to equipment in the event of a fire.
