Rated voltage: Below 1kV.

Rated capacity: 1~50 kvar.

Rated tolerance: -5% ~ +10%.

Dissipation factor: tanδ ≤0.1% at rated power frequency voltage and 20°C (1000Hz).

AC withstand voltage: 2.15× terminal-to-terminal rated voltage for 10s; terminal-to-casing 3kV for 10s.

Maximum allowable overvoltage: 1.10× rated voltage.

Maximum allowable overcurrent: 1.30× rated current.

Self-discharge characteristic: After applying √2×Un DC voltage to a capacitor and disconnecting the power supply for 3 minutes, the residual voltage can drop to below 50V.

Product Features

Core Materials & Advantages

Made of genuine imported films (base: high-isotactic HIPP) with properties like low shrinkage, high strength, low dielectric loss and slow aging, overcoming traditional power capacitor drawbacks.

Safety & Sealing

Avoids traditional failures (oil/wax leakage, casing bulging) via 100% airtight sealing; interior is -0.3pa vacuum, and a pressure-activated explosion-proof device disconnects the capacitor in case of malfunctions.

Size, Installation & Stability

Smaller (1/3 to 2/3 the size of traditional ones) with sufficient compensation capacity, easy design-adjustable installation; excellent internal heat resistance/dissipation prevents overvoltage explosions and ensures stable power equipment operation.
