MANUFACTURING EXCELLENCE

Built for Surge Protection Reliability

Advanced Dielectric Systemy

Manufactured using imported bi-axially oriented double side hazy polypropylene film as dielectric, combined with 99.9% pure aluminium foil as conductor.

Precision Winding & Folding

Elements are wound on modern automatic winding machines in a controlled Class 100 environment. Edge and foil folding reduce partial discharge inception voltage.

Vacuum Drying & Impregnation

Dry packs are wrapped in high-quality insulating paper, placed in pre-treated CRCA or stainless steel containers, vacuum dried, impregnated with non-toxic, non-PCB fluid, and epoxy coated.

Robust Mechanical Construction

Top lids welded using semi-automatic pulse TIG welding machines. Bushings of required BIL ensure leak-proof sealing and safe operation.

APPLICATIONS

Protection Against Electrical Surges

Surge capacitors are used in circuits where damaging voltage transients are expected and equipment protection is critical.

“Optimized for protection against lightning, switching, and transient voltage surges.”

Protection against lightning surges and switching surges

Surge capacitors safeguard equipment from sudden voltage spikes caused by lightning or switching events.

Limiting voltage rise in high voltage motors, transformers, and generators

Ensures voltage rise is controlled for safe operation of high-voltage equipment.

Surge protection during circuit breaker switching operations

Protects equipment from transients caused by circuit breaker operations.

Harmonic capacitor applications requiring surge suppression

Used in harmonic capacitor circuits where surge suppression is critical.

Power systems with frequent transient disturbances

Ensures reliable operation in systems with frequent voltage transients.
