GGD Series low voltage power distribution switch cabinetAC low voltage distribut
GGD type ac low-voltage distribution cabinet is a technical progress development project issued by the ministry of energy in 1991 for the purpose of promoting the technical progress of China's low-voltage distribution industry and accelerating the upgrading of low-voltage distribution switchgear sets.The department of energy's low-voltage switchgear assembly and equipment joint design research group (NLS) completed the design and development, and in October 1992 through the ministry of energy under the auspices of the ministry of approval, currently in the national wide has been widely used.   

   GGD型交流低壓配電柜, 是能源部以促進我國低壓配電行業的技術進步, 加速低壓配電成套開關設備的更新換代為宗旨, 于一九九一年下達的技術進步開發項目。有能源部低壓成套開關設備聯合設備聯合設計研制組(簡稱NLS)完成設計和研制, 并于一九九二年十月通過了由能源部主持的部級鑒定, 目前在全國范圍內巳廣泛運用。

     GGD型交流低壓配電柜符合IEC439 《低壓成套開關設備和控制設備》,GB7251 《低壓成套開關設備》等標準。
Ambient air temperature not higher than +40℃, not lower than -5℃.The average temperature within 24h shall not be higher than +35℃.

 

Rural indoor installation and use, the altitude of the use site shall not exceed 2000m

 

Ambient air relative humidity at the highest temperature of +40℃ the volume does not exceed 50%, at the lower temperature allows for greater relative humidity.{for example, 90% at +20' c] the effect of condensation may occur by chance due to temperature changes should be taken into account.

 

The inclination of the vertical plane during installation should not exceed 5%.

 

Delta equipment should be installed without severe vibration and shock, and in areas where insufficient corrosion of electrical components can occur.

 

Delta users have special requirements can be negotiated with the manufacturer to solve.

 

△周圍空氣溫度不高于+40℃,不低于-5℃。24h內平均溫度不得高于+35℃。

△戶內安裝使用,使用地點的海拔高度不得超過 2000m

△周圍空氣相對濕度在最高溫度為+40℃量不超過 50%,在較 低溫度時允許有較大的相對濕度。{例如+20'℃時為 90% )應考慮到由于溫度的變化可能會偶然產生凝露的影響。

△設備安裝時與垂直面的傾斜度不超過 5%。

△設備安裝時在無劇烈震動和沖擊的地方,以及不足使電器元件受到腐蝕的場所。

△用戶有特殊要求時可與制造廠協商解決。
