High voltage bushing is an important equipment element in power system, which takes on the function of current carrying and insulation when the high voltage line passes through the wall and equipment shell, and the connection between equipment or the grounding of equipment. Since 1958, the company took the lead in the trial production of capacity bushings in China, and after more than 50 years of production and manufacturing experience, it has produced more than 100,000 high-pressure bushings for the power transmission and transformation industry, accounting for about 50% of the total number of domestic online operation at present. On the basis of the original casing production technology, our company actively explores new materials and new technology of casing products, and in 2001, we successfully developed FRP reinforced dry capacitor core, and developed FRP reinforced dry casing series products by using this technology. At present, the company has oil paper capacity type, adhesive paper capacity type, glass fiber capacity type of three kinds of technology of high-pressure bushing production line.

The closing member of a globe valve is a plug-shaped valve disc with a flat or conical sealing surface. The valve disc moves in a straight line along the centerline of the valve seat. The valve stem can be of a lifting-rotating type, suitable for controlling the flow of various types of fluids, including air, water, steam, corrosive media, slurry, oil, liquid metal, and radioactive media. Therefore, this type of shut-off valve is highly suitable for use as a cutoff, regulating, or throttling valve.
