Low Voltage power factor capacitor 250V 3kvar BJ111series single phase cylindrical self-healing capacitor form Motif at Original

Our BJ111-A series capacitors adopted germany and ital-ian advanced equipment and production technology, and we are according to IEC60831 standard strictly. This item are mainly suitable for 50/60hz AC low voltage electric network to improve power factor,reduce reactive loss and improve power quality.A mainstream product type in Europe and America.

Main features:
1.1 More rational design: considering the different capacitances and current carrying capcities, B type connecting terminal is adopted when shell diameter ≥ 86mm. This design has a wider current carrying area and gives off no heat. An overheating protection device is also installed.

1.2 Safe use: with a cynlindrical aluminium stretching shell, this safe and environmental structure has a stronger function of protection, preventing the danger of explosion and leakage.

1.3 With a new high-quality metalized polypropylene membrane specialized for capacitor as insulating medium,which features low ratio characteristics, small body, low temperature and excellent electrical performance, the long life capacitor can tremendously boost the capacity of individual compensation cabinet.

1.4 Wider range of application: featuring unique design and craft, the product can adapt to areas with high
ambient temperature and volitle fluctuations of system voltage.

1.5 Convenient installation and use: the M12/M16 stud type bottom is convenient for users to install and adjust.

1.6 The BJ111 cynlindrical capacitor helps to fulfill a module design of reactor compensation cabinet,
which reduces the cost of equipment unit and makes maintainance easier.

1.7 BJ111 adopts a multigroup paralleled connection, which breaks the whole into parts, i.e. one broken capacitor will not affect the operation of other groups, greatly reducing maintainance cost.

Types and meanings

General working conditons and notes

3.1 Ambient temperature:-25℃ ~ +55℃ Altitude:≤ 2000m
3.2 Relative humidity:40℃ ≤ 20%;20℃ ≤ 90%
3.3 Environmental conditions: no noxious gas and vapour; no conductivity or explosive dust; no violent mechnical
vibration.The equipment should be working with good ventilation instead of stuffy places.
3.4 Notes for capacitor use
3.4.1 The temperature protection switch of B type terminal structural product must be well connected, ensuring
the steady operation of capacitor.
3.4.2 Overvoltage and overheating will shorten capacitor’s life span. Therefore, operation conditons must be
tightly controlled.
