The GGD Low Voltage AD Switchgear is suitably used for electric power consumers in lines of power plants, substations, industrial and mining enterprises etc. in distributing systems with rated working voltage 380V, rated working current up to 3150A for electric conversion, distribution and control of power, lighting and distributing apparatus.

 

As a new generation of low voltage AC dostributing switchgear developed recently, it has been designed on requirements from national electric power ministerial superior authorities concerned, wide electric power customers and design institutions on principle of safety, economical result, reasonability and reliability, featuring high breaking capacity, excellent performance both in short time withstand current and peak value withstand current, flexible electrical schemes, easy combinations, perfect series and applicability, novel structure and high class of protection.

 

The switchgears is manufactured to various relevant standards such as IEC439 “Low Voltage Switchgear and Controlgear” and GB7251 “Low Voltage Switchgear”.

 

      

2.1  Ambient temperature not higher than +40℃ nor lower than -5℃ with 24-hour average not more than +35℃. 

 

2.2  The altitude of application site not over 2000 meters above sea level in indoor use.

 

2.3  The relative humidity of ambient air not exceeding 50% at the maximum temperature of +40℃, and higher humidity permissible at lower temperatures, e.g., 90% at +20℃.   Allowance should be made for the impact of accident condensation caused by abrupt temperature fluctuation.

 

2.4  The inclination to vertical surface when installation not over 5%.

 

2.5  Places where there is no violent shock and impact nor sufficient corrosive materials to corrode electrical components and parts.

 

2.6  Particular requirements may be solved through discussion with the manufacturer.
