In the oil, chemical, mining and other industries, flammable gases or dust when mixed with air can form an explosive atmosphere, which places high demands on the safety of electrical equipment.
Three-phase asynchronous motors with a flameproof enclosure are made in accordance with GB3836.2: the enclosure withstands the pressure of an internal explosion and prevents the spread of flame outward. They are used as a general purpose drive in areas where flammable gases or vapors are present.
For example, the high-efficiency YBX3 and YBX4 motors are rated Exd Ⅱ BT4Gb, Exd Ⅱ CT4Gb and have an IP55 rating, allowing for dusty or humid environments. The motors are designed with Class F insulation and thermal rating of Class B to ensure long life and reliability.
The terminal box is located on top of the housing, allows entry from four sides and facilitates wiring. The products are used in mines, chemical industries and other industrial areas with explosive mixtures, providing reliable drive for safe production.
