Explanatory notes to Article 5.77 of GB50160 (2018 edition)

The original text states: 5.7.7 Flat belt drives are prone to accumulating static electricity, which can generate sparks. According to measurements conducted by the Beijing Institute of Labor Protection in a certain factory, the static voltage accumulated in V-belt drives can reach 2500–7000 V, which is very dangerous. Therefore, this regulation stipulates that belts must not be used in compressors for flammable gases, as well as in pumps for liquefied hydrocarbons and flammable liquids. If antistatic belts are indeed necessary for other rotating equipment, they should be used. The air cooler is installed at a high position with forced ventilation, and can be driven by an anti-static V-belt.
