GGD type fixed low-voltage switchgear
An overview,
GGD ac low-voltage distribution cabinet is suitable for power plants, substations, industrial enterprises such as electric power users as ac 50 hz, rated voltage 380 v, rated current 3150 a as power in the power distribution system, lighting and power distribution equipment of electrical energy conversion, distribution and control. The product high breaking capacity, rated short-time resistance current up to 50 ka. Route plan flexible, convenient combination and strong practicability, novel structure, etc. The product is packaged in our country, one of the representative products of the fixed panel switch cabinet.
The product it "low-voltage complete switch equipment and control equipment", GB7251 "low-voltage complete switch equipment" and other standards.
Second, the conditions of use
◆ Ambient air temperature is not higher than 40 ° C +, not less than 5 ° C, and its average temperature is not higher than within 24 h + 35 ° C.
◆ Indoor installation, use the location of the altitude does not exceed 2000 m.
◆ Ambient air relative humidity when the highest temperature is + 40 ° C is less than 50%, at low temperature are allowed a larger relative humidity, (such as + 20 ° C 90%) should be considered due to the change in temperature may cause condensation effect of accident.
◆ Equipment installation with the inclination of the vertical plane does not exceed 5%.
◆ Equipment shall be installed where no violent vibration and impact, and place of the deficient electric components from corrosion.
◆ Users have special requirements to negotiate with factory to solve.
