High-Performance Power Factor Correction for Industrial Applications
Advanced High-Tension (HT) capacitors designed for individual and centralized power factor correction, harmonic filtering, and enhanced power quality across diverse industrial applications.
Our HT/HV Capacitors
Usha Capacitors offers a comprehensive range of High-Tension (HT) capacitors engineered for superior electrical performance in power factor correction (PFC), harmonic filtering, and voltage stability applications. Utilizing all-film dielectric technology with bi-axially oriented polypropylene film and laser-cut aluminum foil electrodes, our capacitors are impregnated with a non-PCB base fluid for enhanced reliability. Compliant with IS:13925-1994 and IEC-60871 standards, these capacitors are designed for both indoor and outdoor use, delivering up to 1000 kVAr per single-phase unit with a voltage range of 2.4 kV to 24 kV.
Key Features
- All-Film Dielectric: Bi-axially oriented polypropylene film (hazy on both sides, in two or three layers) with laser-cut aluminum foil electrodes for low dielectric losses (~0.1 W/kVAr).
- Non-PCB Impregnation: Environmentally safe fluid ensures reliability and compliance with RoHS standards.
- High Current Capacity: Supports continuous operation at 1.30 times the rated RMS current, excluding transients.
- Robust Construction: Welded bushings and solid terminal studs prevent fluid leaks; folded foil electrodes reduce partial discharge.
- Superior Connections: Extended foils are soldered for high-quality internal connections.
- Corrosion Protection: Oven-cured superior paint system for durability in harsh environments.
- Vacuum Impregnation: Minimizes humidity content for enhanced longevity.
- Temperature Range: Operates reliably from 5°C to 55°C.
- Standards Compliance: IS:13925-1994, IEC-60871, and ISO:9001-2015 certified.
Reliability
- Decreases voltage drop and improves voltage stability.
- Reduces network losses for enhanced energy efficiency.
- Improves power quality by mitigating harmonics and reactive power.
- Suitable for both indoor and outdoor applications.
- Delivers superior electrical performance with maximum output of 1000 kVAr per single-phase unit.
