University Of Pretoria has published the university of pretorias hatfield campus 11kv network consists of four main ring networks, all supplied by the 11kv hilda street substation. the hilda street substation, in turn, is supplied directly by the city of tshwane from the lynnwood substation. major load centres are supplied via local 11000/400v substations, which also supply smaller buildings in their immediate surrounds. two of these load centres, the human sciences (hs) and natural sciences 1 buildings, are undergoing renovations, and the space occupied by these substations will be required to facilitate these upgrades. furthermore, the decentralisation will also facilitate establishing proper separation between mv and lv areas, to ensure the authorised persons for each area can safely work without exposure to the other. this will be achieved by removing the mv switchgear and transformers from the substations, and replacing these with miniature, outdoor substations. as part of this project, the electricity supply for the data centre (d/c), located within the natural sciences 1 (ns1) building, as well as the standby generator unit (sbg) 64, will be upgraded to enhance security of supply and make provision for planned expansion. the successful service provider will, amongst other things, be responsible for the procurement, transport to site, installation, testing and energisation of medium voltage and low voltage electrical infrastructure to give effect to the decentralisation project. see attached document for full details. important information: up can only access tender submissions after the closing date and time. please take load shedding and site congestion into account and plan accordingly. if you need assistance with registration or online submission, contact [emailprotected] for assistance. no e-mail submissions are accepted-only online submissions will be accepted., pretoria.
