Engineered for the most demanding industrial, utility, and infrastructure environments, these panels provide a comprehensive solution for efficient power distribution, precise control, and robust fault protection at critical voltage levels.
Our VCB HT Panels are designed to seamlessly integrate into your existing or new substations, offering a reliable step-down and switching solution from 33KV primary distribution to 11KV secondary networks. Leveraging advanced vacuum interrupter technology, they guarantee fast, efficient, and maintenance-friendly operation, ensuring maximum uptime and operational continuity.
Key Features & Technology Highlights:
Advanced Vacuum Circuit Breaker (VCB) Technology: Utilizes high-performance vacuum interrupters for superior arc quenching, minimal contact wear, and extended operational life. This technology is environmentally friendly, free from SF6 gas.
Robust Enclosure & Construction:
Fabricated from high-grade CRCA steel, offering exceptional mechanical strength and corrosion resistance.
Modular, compartmentalized design for enhanced safety, segregation of live parts, and ease of maintenance.
High IP protection ratings (e.g., IP4X for indoor, IP55 for outdoor options) to protect against dust, moisture, and environmental ingress.
Voltage Levels: Specifically designed for primary distribution at 33KV and secondary distribution at 11KV, with appropriate insulation and clearance.
High Short-Circuit Breaking Capacity: Capable of safely interrupting high short-circuit currents, ensuring rapid fault clearance and preventing damage to upstream and downstream equipment.
Comprehensive Protection & Control:
Integrated with advanced microprocessor-based or numerical protection relays (e.g., overcurrent, earth fault, differential, restricted earth fault).
Equipped with precision Current Transformers (CTs) and Potential Transformers (PTs) for accurate metering and relaying.
Control & indication features include local/remote operation, status indicators, selector switches, and push buttons.
Safety Interlocks & Earthing:
Mechanical and electrical interlocks to prevent mal-operation, ensuring personnel and equipment safety (e.g., preventing breaker operation with earth switch closed).
Robust earthing switches and earthing busbars for secure grounding of dead circuits.
Observation windows (optional) for visual inspection of VCB contacts.
Busbar System: High-conductivity electrolytic grade copper busbars, adequately sized for rated current and short-circuit withstand, fully insulated for enhanced safety.
Metering & Monitoring: Digital multifunction meters provide real-time data for voltage, current, power factor, active power, reactive power, frequency, and energy consumption.
Draw-out / Fixed Type Options: Available in both fixed and draw-out configurations, offering flexibility in maintenance strategies and operational convenience. (Typically fixed type for 33KV, draw-out for 11KV or higher-end solutions).
Ease of Installation & Maintenance: Front access for cabling and components, ensuring streamlined installation, inspection, and servicing.
