NS257: Control and Protection Cabinets and Minor Panel Hardware
This Standard provides for the specification of substation cabinets or panels styles and certain minor hardware they contain.
Ausgrid employs rack and swing frame cabinets for the purpose of housing control, protection and communications hardware and associated copper and fibre wiring.
Cabinets are generally of 19” (45RU) or 24” (45RU) format for indoor use only and are generally installed in ventilated rooms with no climate control.
Scope
The standard applies to the cabinets used for control and protection equipment within zone and sub-transmission substations.
It covers the panel specifications and the minor hardware such as lamps, door locks and similar hardware not directly associated with the design of the control equipment that will be installed in the cabinets.
Not included is the interconnecting wiring between equipment, the wiring terminations nor the wiring between cabinets, as covered under NS251, NS252 and NS253.
