The market place demand for higher voltage switchgear is growing

To some extent, the marketplace demand for higher voltage prefabricated substation will depend on the improvement of energy marketplace. In current years, the worldwide market place demand for energy distribution equipments includes a ascend trend. In conjunction with transformation project of rural energy and ultra higher voltage direct-voltage transmission project, the market of energy transmission and distribution equipments develops repidly.
In China, the annual development price of electrical switchgear ranges from 7% to 11%, and that is an enormous quantity. By most estimates, if we replace the classic switchgear with intelligent electrical switchgear, and we assume that the annual replacement ranges from 3% to 5%, so the aggregate demand will attain 30,000 to 50,000 a year, but exclude the quantity demanded by new projects. Even though we've no correct statistics on the actual demand for low voltage AC switchgear, the price of low voltage switchgear and higher voltage switchgear is roughly 1:12 to 1:15, so we are able to guess that the annual demand for intelligent low voltage switchgears may well ranges from 500,000 to 700,000.
Intelligent switchgears need to function higher efficiency, higher reliability, and have some capacity of self-diagnosis and automatic manage, along with network communication capability. The intelligent switch cabinet will be devided into distribution form, motor manage sort as well as other manage functional sort. The distribution kind utilizes intelligent circuit breaker as core element, and attain remote manage, telemetry, remote communication and remote setting to energy distribution circuit by host personal computer. Though the motor manage kind makes use of transducer and intelligent motor controller as core elements to attain the optimal handle of motor beginning, operating and quit.
The vigorous improvement of new technologies and regularly infiltration inside the field of higher voltage switch gear, it types the present circumstance of combining powerful existing and weak present, the regular technologies and sophisticated technologies. At present, some suppliers have introduced metal-enclosed switchgear handle program in an effort to adapt to greater voltage degree. Some specialists believe that the subsequent ten to 20 years shall be the critical strategic chance period for financial society improvement and scientific and technological improvement, along with the energy transmission and transformation sector will meet golden deveopment chance. For any lengthy time within the future, GIS equipments will come to be a great deal more and much more in demand.
