33KV MV/HT Panel
Product Overview
Our 33 KV HT panels are engineered in a draw-out type configuration, allowing for easy racking out directly on the floor. This feature enhances maintenance efficiency and operational flexibility. Each panel is rigorously type tested in accordance with the international standard IEC-62271, ensuring compliance with global safety and performance benchmarks.
Key Features
- Manual and Electrical Spring Charging: The VCB panels are equipped with both manual and electrical spring charging mechanisms, providing versatility in operation.
- In-Built Anti-Pumping Feature: This safety feature prevents the circuit breaker from closing if it has already been tripped, enhancing operational safety.
- Versatile Coil Voltage Options: The closing and tripping coils are available in multiple voltage configurations: 24V DC, 110V DC and 220V DC, accommodating various system requirements.
- Spring Charging Motor Voltage: The spring charging motor operates at either 230V AC or 110V/220V DC, ensuring compatibility with different electrical systems.
Technical Specifications
- Rated Voltage: 33 kV
- Breaking Capacity up to 26.3 KA for 3 second
- Construction: Robust metal-clad design, fully compartmentalized for enhanced safety.
- Protection Rating: IP5X for high voltage compartments, ensuring protection against dust and water ingress.
Applications
These VCB panels are ideal for use in substations, industrial plants and other high-voltage environments where reliable circuit interruption is critical. With their advanced features and compliance with international standards, they provide a safe and efficient solution for medium voltage power distribution.
