When the transformer fails and no transformer of the same capacity is replaced, you need to temporarily replace the transformer with a larger capacity. You can submit a temporary transformer application to the local power supply business hall. The power supply business hall stipulates that the time for temporary replacement of transformers below 10 kV must not exceed 2 months, and the entire power-receiving transformer must be replaced in the place where the original power was received, and the transformer can be put into operation only after passing inspection. In addition, the increase in capacity during the temporary replacement of transformers does not require the supply of electricity, but because the power administrative department implements two-part tariffs for large industrial enterprises, that is, according to the two parts of capacity and electricity to calculate the electricity fee, and the basic price is in accordance with the industrial enterprise's transformers. The capacity or maximum required amount (ie, the maximum value of the average load every 15 minutes or 30 minutes during the month) is used as a basis for calculating the price, and therefore, the basic electricity fee is charged based on the replaced transformer capacity from the replacement date.
Steel poles are commonly used to carry several types of electric power lines, distribution lines and lighting system. Distribution lines carry power from local substations to customers. They generally carry voltages from 4.6 to 33kV for distances up to 30 miles, and include transformers to step the voltage down from the primary voltage to the lower secondary voltage used by the customer. A service drop carries this lower voltage to the customer's premises.
