GGD Ac low voltage distribution cabinet
Product description
GGD type AC low-voltage power distribution cabinet is suitable for
power users such as power plants, substations, factories and mining
enterprises, such as AC 50Hz, rated working voltage 380V, and rated
working current up to 3150A. For distribution and control.
The GGD AC low-voltage power distribution cabinet is a new type of
low-voltage power distribution cabinet designed in accordance with
the requirements of the superiors in charge of the Ministry of
Energy and the majority of power users and design departments,
based on the principles of safety, economy, reasonableness and
reliability. The product has the characteristics of high breaking
capacity, good dynamic and thermal stability, flexible electrical
scheme, convenient combination, series, strong practicability,
novel structure, protection level, etc., and can be used as an
updated product of low-voltage switchgear.
The GGD AC low-voltage power distribution cabinet complies with
IEC439 "Low-Voltage Switchgear and Control Equipment", GB7251
"Low-Voltage Switchgear" and other standards.
Conditions of Use
• The ambient air temperature is not higher than +40°C, not lower
than -5°C, and the average temperature within 24h must not be
higher than +35°C;
• For indoor installation and use, the altitude of the place of use
shall not exceed 2000m;
• The relative humidity of the surrounding air does not exceed 50%
when the maximum temperature is +40°C, and a larger relative
temperature should be allowed at a lower temperature (for example,
90% at +20°C), taking into account the possibility of temperature
changes Will occasionally produce condensation effects;
• When the equipment is installed, the inclination from the
vertical plane does not exceed 5°;
•The equipment should be installed in a place free from severe
vibration and impact, and in a place where the electrical
components are not corroded
• When users have special requirements, they can be resolved
through consultation with the manufacturer.
