5 distortion temperature is 250 C for PPS, while PBT is deformed at 190 C. Ultimately, PPS is the material of choice for higher grade temperature, humidity, bias (THB) film capacitors. After the housing, epoxy is the second line of defense to protect the capacitor.
Working Principle of capacitor cabinet and its main products
There is no difference between the capacitor cabinet and the capacitor compensation cabinet, the same product is a different call. Most of the load types in the power system belong to inductive load, coupled with the widespread use of power electronics in power-using enterprises, making the power factor of the power grid lower.

Fortunately, aluminum electrolytic capacitors can be self-healed in a process called "capacitor reforming." Capacitor reforming consists of slowly applying voltage to the drive and capacitors using a device known as a variac transformer or a current limited DC
Capacitor banks protection, cautions and maintenance tips
3. Failure of Capacitor Banks. Nowadays, modern capacitors use a "self-healing, safety disconnect" technology, in which the integrity of the capacitor dielectric is maintained very effectively. Under minor fault conditions, gases are released within the capacitor element to effectively weld and close any hole caused by the dielectric fault.
