Taicang proof ceiling fan

Ceiling fans are welcome to call Jiangsu Taicang explosion-proof electrical center Taicang convinced proof ceiling fans classification of such products include explosion-proof ceiling fans, explosion-proof axial fans exhaust fans and other products, its structure consists of explosion-proof motor, explosion-proof junction box and speed controller and leaf composition . Rated operating voltage is generally to 380V, explosion-proof grade up ⅡBT4 level. Example 1 Ex mark, such as electrical equipment for ⅡB class flameproof T3 group, marked as ExdⅡBT3. 2, such as electrical equipment for Class Ⅱ increased safety, temperature class T2 group, marked as ExeⅡT2. 3. Electrical equipment used more than one type of complex, marked the first body type of protection, indicated after other types of protection, such as the main use of increased safety flameproof components built ⅡC class, temperature class T4, flag ExedⅡCT4 . 4, such as electrical equipment for dust-proof dust-T11 group. Flag: DIPDPT11. Proof ceiling fan applies to the surrounding medium containing ⅡA, ⅡB level temperature groups T1 ~ T4 group explosive gas mixtures place as the ventilation cooling in AC 50Hz, voltage to 200V circuit. Work reliably under the following conditions: 1, altitude does not exceed 2000m; 2, ambient operating temperature is -20 ℃ ~ + 40 ℃; 3, ambient air relative humidity less than 95% (+ 25 ℃) 4, containing ⅡA, ⅡB Temperature Class T1 ~ T4 group explosive mixture properties; 5, no significant shake the shock vibration place; 6, no damage to the insulation of gas or vapor environment; 7, no dripping place; 8, pollution degree 3; 9 , installation category Ⅱ class
