Introducing the Advanced 36 kV Vacuum Capacitor Switch from Usha Electric
Usha Electric proudly presents the redesigned 36 kV Vacuum Capacitor Switch, a state-of-the-art solution engineered for reliable and efficient switching of capacitor banks in medium-voltage power distribution systems. Leveraging advanced vacuum interruption technology and robust construction, this switch ensures minimal maintenance, high durability, and optimal performance, making it an ideal choice for industries such as steel, cement, power utilities, and heavy manufacturing.
Key Features of the Redesigned 36 kV Vacuum Capacitor Switch
1. Advanced Vacuum Interruption Technology
The 36 kV Vacuum Capacitor Switch employs vacuum interrupters to deliver arc-free switching, ensuring reliable operation for high-frequency capacitor switching. This technology minimizes contact wear, reduces inrush currents, and achieves a C2 restrike rating, making it suitable for heavy-duty applications with frequent cycling.
2. High Reliability and Safety
Compliant with IEC 62271-103 and ANSI C37.66 standards, the switch is designed for safe and consistent performance in harsh environments. Its solid dielectric insulation, using hydrophobic cycloaliphatic epoxy (HCEP) resin, offers excellent resistance to moisture, ozone, and UV light, ensuring high dielectric strength and reliability in dusty or polluted conditions.
3. Versatile Configurations
Available in current ratings up to 630A and designed for 36 kV ungrounded systems, the switch supports both single-phase and three-phase gang-operated configurations. It is compatible with Automatic Power Factor Correction (APFC) panels and can be integrated with industry-standard capacitor controls for Zero Voltage Closing (ZVC), reducing transients during operation.
4. Compact and Low-Maintenance Design
The switch features a compact, pole-mounted or indoor design, optimizing space in electrical setups. Its magnetic actuator and maintenance-free vacuum interrupters eliminate the need for gas, oil, or foam, reducing lifecycle costs. Periodic thermographic surveys are recommended to ensure peak performance.
5. Eco-Conscious and Durable
Constructed with environmentally friendly materials, the Vacuum Capacitor Switch aligns with Usha Electric’s sustainability goals. Its corrosion-resistant enclosure with IP55/IP65 protection ensures durability in extreme climatic conditions, providing years of trouble-free operation.
