Major Substations Building Design Standard
NS185: Major Substations Building Design Standard
Details the performance and design criteria for the architectural and structural design of buildings for Major Substations with the voltages of 132kV, 66kV, 33kV and 11kV.
Scope
This Network Standard details the requirements for the Architectural, Civil and Structural engineering design of buildings for major substations.
This standard provides the performance and design criteria for buildings in major substations with the voltages of 132kV, 66kV, 33kV and 11kV.
Refer to NS186 for details of the performance and design criteria for civil works associated with these major substations.
Refer to also the relevant network standard for building design requirements related to ventilation, substation overpressure, active and passive fire mitigation.
This document does not include detailed information for yard structures in substations, nor does it include provisions or information for distribution substations, kiosks or pole top equipment such as transformers, regulators or capacitors.
