![]() Although domestic brands have an upward trend in this year, the market share of domestic brands is still not obvious. The share of foreign brands in the domestic inverter market is still maintained at 60% - 70%. Except for the two giants abb and Siemens, which occupy 21% of the market share, the market share of 3-10 is not different. And the explosion-proof performance ofĮxplosion-proof models is onformed to the requirements of Standard GB 3836.1- 2000 ElectricalĪpparatus for Explosive Gas Atmospheres–Part Ⅰ: General Requirements, and Standard GB 3836.2-Ģ000 Electrical Apparatus for Explosive Gas Atmospheres–Part Ⅱ: Flameproof Enclosure “d”.The market share of low-voltage inverter market has declined slightly and the market concentration has decreased. Their general performance is conformed to the requirements of Standard JB/T 8219- Electrical Actuatorsįor Industrial-process Measurement and Control System. Products are divided into two models depending on service environment: normal and explosion-proof. Globe valves, throttle valves, ball valves, butterfly valves and various modulating valves precisely.
