Overview
GGD low voltage switchgear is suitable for power plants, substations, factories and mines and other power users with AC 50Hz, rated working voltage 380V, and rated working current up to 3150A distribution system. It is used for power conversion, distribution and control of power, lighting and distribution equipment.
GGD low-voltage complete switchgear is a new type of low-voltage distribution cabinet designed according to the requirements of the competent superiors of the Ministry of Energy, the majority of power users and design departments, based on the principles of safety, economy, rationality and reliability. The product has the characteristics of high breaking capacity, good dynamic thermal stability, flexible electrical scheme, convenient combination, series, strong practicality, novel structure and high protection level, and can be used as an updated product of low-voltage complete switchgear.
GGD low voltage switchgear cabinet complies with IEC 439 "Low voltage switchgear and control equipment", GB7251 "Low voltage switchgear" and other standards.
Environmental Conditions for Use
The ambient air temperature shall not be higher than +40℃ and not lower than -5℃, and the average temperature within 24 hours shall not be higher than +35℃.
For indoor installation, the altitude of the use location shall not exceed 2000m.
Relative humidity should not exceed 50% at +40℃. Higher relative humidity is allowed at lower temperatures (e.g. 90% at +20℃), considering occasional condensation.
The equipment should be installed with an inclination of no more than 5° from the vertical plane.
The equipment should be installed in a place without severe vibration, impact, and where the electrical components are not subject to corrosion.
If the user has special requirements, they can negotiate directly with the manufacturer to find custom solutions.
