Surge Current200 times of rated current Dielectric Loss≤0.2 Watt / Kvar Voltage TestBetween terminals: 2.15 Un for 10 seconds. Between terminals to container: 3000VAC for 10 seconds Safety SystemSelf protection device Case MaterialRust-Proof painted steel ExecutionIndoor, minimum distance between units : 50mm StandardIEC60831 / GBT12747 ADVANTAGES: 1. Excelent reliability *Using the world's most advanced Switzerland (Metar) automatic rollwinding machineto wind the polyprolilene film. *Using the computer controlled metal spraying machine from Itally spray the metal powder. * Each capacitor's technique data is selected and managed by computer 2. Durable * The adaption of special combined electrode material and intensify insulating material little loss of capacitance during working. * Each capacitor core has been heat set in high vacuum silicone oil. * The capping machine is from Italy * The metal case is after the treatment of rust-proof and impact resistance. 3. High compact *Save space and light, easy to handle for attachment. 4. Whole dry structure: *The capacitor case is filled by anti-flaming black gel to avoid the polution by oil. 5.Protected *The power capacitor is with over-voltage protection devices.
