GGD型交流低压配电柜
一、概述：
适用于发电厂、变电站、厂矿企业等电力用户作为动力、照明及配电设备的电能转换、分配与控制之用。

二、使用环境条件：
1、户内安装使用时，使用地点海拔高度不超过2000m；
2、设备安装时与垂直面的倾斜度不超过5°；
3、周围环境温度：－20℃～＋40℃，并且24h内平均温度不高于＋35℃；
4、空气相对湿度在温度＋40℃时，不超过50%，在温度较低时，允许有较高的相对湿度（如在＋20℃时为90%），应考虑到由于温度的变化可能会偶然产生凝露的影响；
5、设备应安装在无剧烈震动和冲击的地方，及不足以腐蚀电器元件的场所。

GGD Type A.C. Low Voltage Distribution Cabinet
Summarize:
Applicable to the power plants, transformer substation, industrial and mining enterprises and other electricity users as the driving force, lighting and electric energy transforming and distribution and control of power distribution equipment.
Use environmental conditions:
When install and use indoors, altitude should less than 2000m
Install gradient less than 5°
Environmental temperature : -20℃ ～ +40℃, the average temperature should less than +35℃ within 24h
Relative humidity is not more than 50% at the highest temperature +40℃, when the temperature is lower, a higher relative humidity is allowed (for example when +20℃ is 90%), should consider to the influence by congeals the dew due to the temperature change accidentally
The equipment should be installed in the place without intense vibration and impact, and the place is insufficient to corrode the electric appliance parts
