IP protection level: IP (INTERNATIONAL PROTECTION) protection level system is drafted by IEC (INTERNATIONAL ELECTROTECHNICAL COMMISSION). The generators are classified according to their dust-proof and moisture-proof characteristics. The foreign objects referred to here include tools, human fingers, etc., should not touch the live parts of the generator to avoid electric shock. The IP protection level is composed of two numbers. The first number indicates the level of the generator against dust and foreign objects. The second number indicates the degree of airtightness of the generator against moisture and water intrusion. The larger the number, the protection The higher the level, the protection levels indicated by the two marked numbers are shown in Table 1 and Table 2.
Such as IP21:
Classification and definition of generator protection level (first digit)
Classification and definition of generator protection level (the second digit)
The commonly used protection grades of motors are IP21, IP23, IP44, IP54, IP55, IP56, and IP65.
(For land use) The general factory standard of generator protection level is IP21, if IP23 is required, it can be mentioned when ordering.
IP21 generator, generally for land use
IP23 generator, generally available for marine use
IP44 water-cooled generator, generally used in ships
