Tri-rated Cable to BS6231
Application and Description
Tri-rated Cable panel wiring is a high temperature, flame retardant cable designed for use in the switch control, relay and instrumentation panels of power switchgear and for purposes such as internal connectors in rectifier equipment, motor starters and controllers. Tri-rated Cable is sometimes referred to as BS6231 Cable or Panel Wire.
