Resistor is an electronic component that has the function of partial voltage and shunt. It can not only change the voltage, but also the transformer. It can boost or lower the voltage, and the resistor can play the role of step-down. Power consumption is enormous. In recent years, transformers and resistors have developed rapidly, and transformers have advanced in the process of urbanization, and transformers have also ushered in a golden age.


Since the 21st century, with the development of urbanization and the speed of construction, both the resistor and the transformer production have ushered in the golden development period. The transformer products have a comparative performance in terms of capacity, output, voltage level and capacity. Great improvement, but also promoted the continuous expansion of the industry.
 
According to relevant data, the market size of the transformer industry is generally growing in 2012-2017, and the growth rate is relatively volatile. In 2012, the sales revenue of the transformer industry reached 317.074 billion yuan, a year-on-year increase of 9.28%. In 2014, the sales revenue of the transformer industry exceeded 400 billion yuan. In 2016, the sales revenue of the transformer industry reached 443.374 billion yuan, a year-on-year increase of 12.24%. As of 2017, the sales revenue of the transformer industry reached 437.975 billion yuan, a year-on-year decrease of 1.22%. It is estimated that by 2018, the sales revenue of the transformer industry will likely rebound, reaching 476.374 billion yuan, an increase of 8.77%.
