Equipment Foundation Drawings
The following CB/CT pads are utilised for all standard TP period supplied 110 kV CBs and CTs. The CB/CT pads have been designed to be used at all Transpower sites with two different widths dependant on seismic acceleration. They can also accommodate being cast-insitue or precast offsite if required. In addition cast in bolt cages or "Chemset" or similar HD bolts can be used.
NOTE: The SLS2 for the design of the stand and foundation was checked for a 250-year return period (RP) and is therefore outdated with respect to the current requirement to use a 500-year RP. The SLS2 needs to be checked for site-specific conditions before applying this design
