The market demand for high voltage switchgear is increasing

To some extent, the market demand for high voltage switchgears depends on the development of power market. In recent years, the global market demand for power distribution equipments has a ascend trend. Along with transformation project of rural power and ultra high voltage direct-voltage transmission project, the industry of power transmission and distribution equipments develops repidly.

In China, the annual growth rate of electrical switchgear ranges from 7% to 11%, and this is a huge quantity. By most estimates, if we replace the traditional switchgear with intelligent electrical switchgear, and we assume that the annual replacement ranges from 3% to 5%, so the aggregate demand will reach 30,000 to 50,000 a year, but exclude the quantity demanded by new projects. Although we have no accurate statistics of the actual demand for low voltage switchgears, the rate of low voltage switchgear and high voltage switchgear is approximately 1:12 to 1:15, so we can guess that the annual demand for intelligent low voltage switchgears may ranges from 500,000 to 700,000.
Intelligent switchgears should feature high performance, high reliability, and have some ability of self-diagnosis and automatic control, as well as network communication capability. The intelligent switch cabinet can be devided into distribution type, motor control type and other control functional type. The distribution type uses intelligent circuit breaker as core component, and achieve remote control, telemetry, remote communication and remote setting to power distribution circuit by host computer. While the motor control type uses transducer and intelligent motor controller as core components to achieve the optimal control of motor starting, running and stop.
The vigorous development of new technology and constantly infiltration in the field of high voltage switch equipment, it forms the current situation of combining strong current and weak current, the traditional technology and advanced technology. At present, some manufacturers have introduced GIS intelligent control system in order to adapt to higher voltage degree. Some experts think that the next 10 to 20 years will be the important strategic opportunity period for economic society development and scientific and technological development, and the power transmission and transformation industry will meet golden deveopment opportunity. For a long time in the future, GIS equipments will become more and more in demand.
