Single-Phase and Three-Phase Oil Type Metallized Film Capacitors with Safety Explosion Proof
Aihua Infinity Capacitors (Suzhou) Co., Ltd launched a New Oil-Type AC Capacitor in January 2019. The product uses metallized polypropylene film which is metallization in high vacuum environment and wound into cylindrical bobbin on high precision winding machine, sprays metal layer on both ends, encapsulated in corrosion-resistant aluminum can after welding and assembling and then injected with soft PU resin in vacuum. The products are tested and packaged by automatic production line, which ensures the consistency and reliability of product quality.
Product voltage range is 230-850Vrms and the range of capacitance is 10-600uF. It has single-phase or three-phase capacitors with dual security protection: self-healing and over-pressure protection. In case of failure, the explosion-proof mechanism of the product acts, and the capacitor is disconnected from the circuit to avoid the occurrence of larger faults. The maximum fault current is 10KAFC.
The product is impregnated with oil, which improves the corona starting voltage of the capacitor, and also improves the heat dissipation ability of the capacitor, so that the capacitor can work under high temperature and harsh heat dissipation conditions. Products through UL certification and widely used in UPS, motor drive, converter and etc.
