BFM BAM FFM High Voltage Shunt Power Capacitor

Jinneng electric BFM BAM FFM High voltage shunt power capacitor is specifically designed for 50Hz/60Hz AC power systems to improve power factor.reduce reactive power damage, improve voltage quality, and Maximize efficiency of power generation & supply equipment.

This capacitor parallel connection in HV systems,frequency rating is 50Hz / 60Hz (dual-rated).It's widely use in electrical substations,Industrial plants.

 

 

● The altitude does not exceed 1000m, the ambient temperature is -40 ~ +45°C(Class B rating).

● There is no violent mechanical vibration, no harmful gas and steam, no conductivity or explosive dust in the installation site.

● Capacitors should be guaranteed to operate in good ventilation conditions,not allowed in closed and unventilated conditions.

● Capacitor wiring should be flexible wire, and the whole circuit should be in good contact.

 

 

 

The main difference between BFM, BAM, and FFM capacitors is the medium type and application scenario. ‌
High voltage capacitors generally have BAM,BFM,BWF,BFF series, we are generally common is BAM series.
The first letter is the series code, B stands for shunt capacitor.
The second letter is the code for the liquid medium in the high voltage capacitor, F stands for diarylethane and A stands for benzyl toluene.

High voltage capacitors using benzyl toluene will be suitable for cold areas.
The third letter M is the code for the solid medium, representing the full film medium.
Medium type
●‌ BFM: indicates the use of full-film medium (Film), that is, polypropylene film as the medium.
●‌ BAM: indicates the use of full-film medium (Film), the same as BFM.
●‌ FFM: indicates the use of Film and Paper composite medium, that is, polypropylene film and paper composite medium.

 

 

‌ ● Rated voltage：BFM/BAM has a wide range of rated voltage, including 6.3kV, 6.6kV, 10.5kV, 11kV, 12kV, etc.
‌ ● Rated capacity：from 30kvar to 334kvar range,special requirement also can meet.
‌ ● tanδ/dissipation factor: Granular Composite Dielectric: tanδ ≤ 0.08%,Full-Film Dielectric: tanδ ≤ 0.05%

 The main difference between BFM and BAM capacitors is whether they contain an internal fuse.

 

 

●BFM/BAM：suitable for power frequency AC power system above 1kV, mainly used to improve power factor, reduce reactive power loss, improve voltage quality,and Maximize efficiency of power generation & supply equipment.

●‌FFM‌ : Specific application scenarios and performance parameters are not explicitly mentioned in the search results, but generally FFM capacitors may have different electrical properties and applicable conditions, which may be different from BFM/BAM.

 

 

● The capacitor consists of a tank and a core. The tank is made of thin steel plates sealed by welding and is equipped with bushings (porcelain insulators) for electrical connections.Lifting lugs are welded on both sides of the tank for installation, with one lug fitted with an earthing bolt for grounding.

● The capacitor core is formed by stacking multiple elements and insulating layers.
Element Construction: Each element is made by rolling two aluminum foils (electrodes) with a dielectric material (film-paper composite or all-film dielectric) in between, then flattening the assembly.
The elements are connected in series or parallel to meet different voltage and capacitance requirements.

● Internal Fuse Protection (if equipped)
Each element is connected in series with a fuse. If an element breaks down, the healthy parallel elements discharge into it, causing the fuse to blow within milliseconds-isolating the faulty element and allowing the capacitor to continue operating

● Three-phase units use star (Y) connection

● Liquid Dielectric Function
The liquid dielectric impregnates the solid dielectric and fills internal gaps. It is selected for excellent electrical properties and compatibility with other materials in the capacitor.
