HT VCB Panel Board: Robust High-Voltage Distribution & Protection
The HT VCB (High Tension Vacuum Circuit Breaker) Panel Board is a state-of-the-art solution engineered for reliable, safe, and efficient high-voltage power distribution and protection. Designed for critical industrial, utility, and large commercial applications, our HT VCB Panel Boards provide uncompromising performance where safety and continuity of power are paramount.
Utilizing advanced Vacuum Circuit Breaker technology, these panels offer superior fault interruption capabilities, extended operational life, and significantly reduced maintenance compared to older technologies.
Rapid Arc Quenching: Employs vacuum interrupters for swift and efficient arc extinction during fault conditions, minimizing contact erosion.
High Breaking Capacity: Capable of interrupting high short-circuit currents with exceptional reliability.
Extended Lifespan: Offers a high number of mechanical and electrical operations, ensuring long-term service with minimal wear.
Environmentally Friendly: SF6-free design, contributing to a greener footprint.
Low Maintenance: Vacuum technology drastically reduces the need for routine maintenance and contact inspections.
2. Comprehensive Protection & Safety
Integrated Numerical Relays: Equipped with advanced protection relays for precise detection and clearance of overcurrent, earth fault, short circuit, under/over voltage, and other critical anomalies.
Robust Interlocking Mechanisms: Incorporates mechanical and electrical interlocks to prevent unsafe operations (e.g., racking in/out with breaker closed, earthing switch operation while power is on).
Personnel Safety: Fully compartmentalized design, separate busbar chambers, and arc-resistant options enhance safety for operating personnel.
Pressure Relief Vents: Designed to safely channel fault gases and pressure in the event of an internal arc.
Earthing Switch: Integrated high-speed earthing switches for safe maintenance and testing procedures.
3. Modular & Durable Construction
Modular Design: Highly flexible and customizable configurations to meet specific project requirements, easily expandable for future capacity needs.
Robust Enclosure: Manufactured from high-grade CRCA steel, powder-coated for superior corrosion resistance and durability in harsh industrial environments.
Withdrawable Breaker Mechanism: Facilitates easy and safe inspection, testing, maintenance, or replacement of the VCB, minimizing downtime.
Accessibility: Front access for controls, metering, and routine maintenance; optional rear access for convenient cable termination.
IP Protection: High ingress protection (e.g., IP4X) against dust and foreign objects.
4. Advanced Control, Monitoring & Metering
Real-time Data: Comprehensive metering for voltage, current, power factor, frequency, active/reactive power, and energy consumption.
Status Indication: Clear visual indicators for breaker position, spring charge status, trip indications, and fault alarms.
SCADA/BMS Integration: Optional communication protocols (Modbus, IEC 61850) for seamless integration with plant SCADA or Building Management Systems for remote monitoring and control.
User-Friendly HMI: Intuitive Human-Machine Interface for local operation, data visualization, and event logging.
5. Adherence to International Standards
Designed, manufactured, and rigorously tested in compliance with IEC 62271-200, IS (Indian Standards), and other relevant industry standards, ensuring peak performance and safety.
