1. Product use
Capacitors in this manual are shunt capacitor units (hereinafter referred to as capacitors) applicable to AC power systems with nominal voltage above 1kV and frequency of 50 or 60Hz, which are used to improve power factor and grid quality. The product adopts GB/T 11024.1 and DL/T 840 standard.
2. Product model and meaning

高压并联电容器

For example:
BAM12-500-1 w
Description: Single phase outdoor shunt capacitor made of benzyl-toluene impregnated polypropylene film medium, rated voltage 12kV, rated capacity 500kvar3. Product structure
The capacitor is mainly composed of three parts: case, core and impregnating agent. The shell is made of high quality sheet steel bent and sealed by welding. The cover of the case is welded with the lead line sleeve, and the two sides of the case are welded with the hoist for handling and installation. The core consists of a number of components and insulating parts connected in series and parallel. The components are made of polypropylene film as solid medium, aluminum foil as plate, and the case is filled with excellent impregnating agent.
4. Conditions of use
4.1 Environment and Operating Conditions:
a. The altitude of the area to be used is not more than 1000m.
b. Ambient temperature: -40 ℃ ~ +45℃.
c. The site shall be free from violent mechanical vibration, harmful gas and steam, and conductive or explosive dust.
4.2 Other Conditions of Use:
Before the capacitor is put into operation, the remaining voltage between terminals shall not exceed 10% of the rated voltage.
4.3 When the capacitor involves high relative humidity, rapid mold growth, corrosive atmosphere, pollution, altitude over 1000m
In case of any special use conditions such as earthquake area, the Buyer shall notify the Company and determine the type of product and special preventive measures to be taken through negotiation.
