BSMJ Series Low Voltage Shunt Power Capacitor

Specifications

General Description 

Brand of self-healing type low voltage shunt capacitor, made of the advanced metallized film, is produced strictly in accordance with the National

Standard and IEC Standard by the introduced advanced foreign techniques and equipment. The device is mainly suitable for low voltage electric

net work to improve power factor, reduce reactive loss, and better the voltage quality.

Main Features

1. Small volume and light weight: It is only 1/4 and 1/5 of the weight and volume of the outdated products respectively.

2. Low loss: With the actual loss less than 0.1%, the capacitor, itself, has low consumption of energy, little radiation, low temperature rise, long

service life, and good energy, conservation feecet.

3. Excellent self -healing performance: When a part of the inolation is fed through due to the over voltage, it is capable of self-heaing so as to continue

the normal operation, therefore there liability is in proved greatly.

4. Safety: Equipped with self-discharging resistant and safety devices inside, it is safe and reliable.

5. Without oil leakage: In order to avoid oil leakage during operation so as to protect the environment, it employs the microrystlline wax as the Impregnant , which remains solid atordinary temperature and has a drip melting point higher than 70°C

Scope of Application

The product complies with IEC 30-1998 standard.
