Rust is the impact disconnectors safe and reliable operation of the primary problem, regular anti-rust treatment, lubricant was added to each transmission parts, particularly the use of performance is better than butter, molybdenum disulfide lubricant. Brass sleeve replacement of the steel substrate surface of the sintered bronze plus modified PTFE composite bushings, and end portions of the outer surface of the tin to prevent corrosion. Organizations box with high quality stainless steel products disconnectors prices isolation switch base to transform gas pressure isolation switch, drill a hole in the base, the operation of molybdenum disulfide added periodically to ensure that the bearing does not rust. Local isolation switch does not apply are: ⑴ a conductive or chemical action of gases, vapors place; ⑵ of fire or explosive atmosphere (if gas pit); ⑶ large quantities of dust gathering place; ⑷ vibration and strong or impacts; ⑸ humid places and tropical regions. Load isolation switch, Huayi Electric Power (certified), Changsha, Xi'an isolation switch provided by the Huayi power plant.
