Analysis of Kazakhstan power transformer Market in 2021

According to Interfax news agency, at present, Kazakhstan has an excess power supply. In 2020, the annual power generation will reach 106 billion kWh and the power consumption will be about 105 billion kWh (there are 155 power stations in China, of which 69% are coal-fired power stations and 9% are hydropower stations). However, accordingContinue reading “Analysis of Kazakhstan power transformer Market in 2021”

Market analysis of power distribution transformer in Uzbekistan in 2021

Market analysis of power distribution transformer in Uzbekistan in 2021Martin, chief economist of hengfengyou electric, made a simple investigation on the market situation of Uzbekstan power transformer, but got the basic conclusion: the transmission and distribution equipment in Ukraine is seriously aging (built in the 1960s-1980s). The new president vigorously develops the economy and has a strong demandContinue reading “Market analysis of power distribution transformer in Uzbekistan in 2021”

What is the difference between box type substation and box type transformer?

What is the difference between box type substation and box type transformer? Transformer is a device that transforms AC voltage, current and impedance. When AC current is connected in the primary coil, AC magnetic flux will be generated in the iron core (or magnetic core) to induce voltage (or current) in the secondary coil. TheContinue reading “What is the difference between box type substation and box type transformer?”

What is a single-phase control transformer

What is a control transformer? On CNC lathes or other electrical equipment that must have a high safety factor, the power supply of the control circuit must be low-voltage, some 127V and some 36V. Therefore, it is necessary to change 380V or 220 voltage from 100-150w transformer to this kind of voltage. This kind of transformerContinue reading “What is a single-phase control transformer”

Water ingress and moisture of oil immersed transformer

Moisture in the water of oil immersed transformer will do great harm to the electrical and physical and chemical properties of insulating medium. The existence of moisture will destroy the insulation strength of transformer oil, promote the corrosion of organic acids to copper, iron and other metals, and catalyze the oxidation of transformer oil, resulting in theContinue reading “Water ingress and moisture of oil immersed transformer”

How to determine the reasonable capacity of transformer and select transformer?

1、 What is the voltage change rate of transformer?The voltage change rate of voltage regulator is one of the main performance indexes of transformer. When the transformer supplies power to the load, the voltage at the load end of the transformer will inevitably drop. Compare the falling voltage value with the rated voltage value, andContinue reading “How to determine the reasonable capacity of transformer and select transformer?”
