What power rating should the temporary power supply have during construction?
Thread Content
I would like to ask: for a chemical plant project with an investment of 6 billion, what capacity should the temporary power supply have during construction? In other words, what standards should be used to determine the capacity of the temporary power supply? Thank you
It has nothing to do with the size of the project; it is calculated based on the electrical equipment actually used
The general contractor for construction must, based on the construction organization plan and construction scheme, as well as by keeping track of the power consumption of welding machines and other electrical tools as well as all electrical equipment such as those used for office lighting, prepare a temporary power supply plan for the construction site. This is quite professional. It is one of the three connections and one leveling tasks required at the start of a project. There are still a series of procedures to go through later
Additionally, if the electricity consumption exceeds your capacity to supply power, it is necessary to submit an application to the higher-level power supply authority for approval, or to arrange separate wiring and equipment for dedicated power supply.
It mainly depends on the power capacity to accommodate electrical equipment such as welders and cranes during peak construction times, as well as the power supply capacity of the power grid company located near the project site. For a chemical processing project of your scale, it is generally advisable to use a 35KV main step-down substation or 10KV regional substations; depending on the size of the project area, multiple 10KV substations may be necessary.
