Advantages
● Cylindrical aluminum can with an expandable cover: When the internal pressure increases, the expandable cover will stretch, triggering the explosion-proof device to break and cut off the capacitor's power supply, thereby preventing further damage.
● External discharge resistor: It prevents overheating damage during the discharge process, enables free heat dissipation, and provides a reliable and maintainable active discharge path, making it more suitable for industrial power equipment.
● Filler material and characteristics: Epoxy resin is adopted, which is suitable for high-temperature environments.It features flame retardancy, explosion proof, and leak resistance. It can be installed reversely outdoors, will not splash after an explosion, making it easy to clean.
● Certificate: This type of capacitor has passed the authoritative IEC 60831-1/2 tests, conducted by a testing laboratory that complies with CNAS 17025, and has obtained the TÜV Rheinland certificate.
