The prospect analysis and survey of the voltage regulator industry shows that the domestic frequency converter market is developed with the entry of foreign brands. Foreign brands are mainly preconceived. At present, the share of the domestic voltage regulator market is about 70%. Most local enterprises have not been established for a long time, many products have entered the market for a short time, and it is difficult to compete with international well-known brands in terms of product maturity and brand awareness.

Voltage stabilizing industry is a bridge to graft heavy equipment and production technology, and an important medium to realize industrial automation and informatization. With the progress of science and technology, from life to production, from civil to industry, from variable frequency air conditioning to high-speed trains, and even to the electrical automation control field of industrial and mining enterprises, voltage stabilization is ubiquitous and the effect is getting better and better. To a large extent, we have entered the "frequency conversion era", and there is more and more space for frequency conversion to create value.

According to industry experts, the device that usually converts AC with fixed voltage and frequency into AC with variable voltage or frequency is called "voltage regulator". The test data show that the power saving rate of motor system using voltage regulator is generally about 30%, and in some high occasions, it can reach 40% - 60%. The energy-saving effect is remarkable. Therefore, voltage regulator has become the development direction of motor energy saving.

Experts also said that if China's relevant industries vigorously promote the use of voltage stabilizing technology, consciously equip high-performance and high-stability high-end industrial special voltage regulators from technical transformation and process innovation to the early design of new projects, it will create huge space for energy conservation and emission reduction in China's relevant industries.

In recent years, due to the shortage of energy and the requirements of production technology, high-voltage voltage voltage stabilization and speed regulation has become the only way for large-scale production enterprises to save energy, and the domestic market demand for high-voltage frequency conversion and speed regulation has increased sharply. The 12th Five Year Plan for energy conservation and environmental protection industry development of the State Council also clearly puts forward that technologies and equipment such as voltage stabilization and speed regulation should be vigorously promoted for motors and driving equipment, so as to improve the overall operation efficiency of the motor system.

Experts believe that in the next few years or even longer, the development trend of China's deep economic transformation, quality improvement and efficiency will provide a broader growth space for the regulator market.

Statistics show that China's voltage regulator market is currently in a period of rapid growth and is widely used in textile machinery, air conditioning, elevator, metallurgy and other industries. In recent years, China's voltage regulator market has maintained a growth rate of 12% ~ 15%. It is expected that the demand of voltage regulator market will still maintain a growth rate of more than 10% in the next five years. According to the analysis and statistics on the prospect of transformer regulator industry, the total potential market space of voltage regulator in China is about 120 billion ~ 180 billion yuan.
