BSMJ self-healing low voltage shunt capacitor
small in size, lightweight and good specific property
low energy consumption, low heat radiation and temperature rise.
Excellent healing-ability, improves reliability and shelf-life.
Internal discharge resistor and fuse ensure the security operation.
Semisolid impregnant ensures no leakage.
