● It is applicable to power conversion, distribution and control of power plants, substations, industrial and mining enterprises, petrochemical, metallurgy, high-rise buildings, hospitals, expressways, municipal engineering, and other projects where the electrical system is used as power supply, power distribution, and motor centers.

● The device is a new type of low-voltage distribution cabinet featured with safety, economy, rationality and high reliability. It has the characteristics of convenient and flexible combination of electrical schemes, stable series, strong practicability, high protection grade, and long service life.

Normal service conditions： 

● Ambient air temperature shall not exceed + 40℃, and the average temperature within 24h shall not exceed + 35℃.

● Lower limit of ambient air temperature is - 5℃.

● Atmospheric conditions: clean air, up to + 40℃. The relative humidity shall not exceed 50%. Higher relative humidity is allowed at lower temperature. For example, 90% at 20℃. However, it should be considered that moderate condensation may occur occasionally due to temperature changes.

● Pollution level 3: conductive pollution exists, or dry non-conductive pollution becomes conductive pollution due to condensation.

● Sea altitude may not exceed 2000m.

● The inclination to the vertical plane may not exceed 5 degree when installing the equipment.

● The equipment shall be installed at places free of violent vibration, impact, or strong corrosion which might impair  the electrical components

★ For special use conditions beyond normal use conditions, please consult to reach an agreement.
