As a professional manufacturer of electrical equipment, Jinhua Dika Electrical Equipment Co., Ltd. specializes in providing reliable and efficient power distribution solutions. Our 40.5KV Rated Indoor GIS Panel Kyn61 MV 33KV VCB is engineered for modern substations, offering a compact, safe, and high-performance alternative to traditional air-insulated switchgear. Designed to meet the rigorous demands of power distribution networks, this panel integrates advanced vacuum circuit breaker technology within a gas-insulated structure, ensuring superior insulation, minimal maintenance, and enhanced operational safety in indoor environments.

This product is a cornerstone of our portfolio, reflecting our commitment to quality certified under the ISO9001 standard. With an annual export value of US$1 Million - US$1.5 Million and a presence in markets worldwide including North America, Southeast Asia, Europe, and Africa, we have built a reputation for delivering robust electrical equipment that power industries and communities. Our panel is designed to be a dependable component in your substation, facilitating efficient power control and distribution.

Core Product Features & Technical Advantages:

Advanced Gas Insulation: The GIS design utilizes SF6 gas (or similar) for insulation, which provides a much higher dielectric strength than air. This allows for a significantly more compact footprint compared to AIS (Air-Insulated Switchgear), saving valuable space in indoor substations.
High Reliability 33kV VCB: At the heart of the panel is a 33kV rated Vacuum Circuit Breaker. Vacuum interruption technology offers a long electrical life, minimal arc energy, and requires no arc quenching medium maintenance, leading to high reliability and lower lifecycle costs.
Kyn61 Metal-Clad Design: Constructed according to the Kyn61 standard, the panel features a robust metal-clad structure. This design provides compartmentalization between different functional sections (busbar, circuit breaker, cable compartment), enhancing safety for personnel and equipment.
Enhanced Safety & Maintenance: The sealed gas-insulated compartments minimize exposure to live parts, reducing the risk of electrical faults and improving personnel safety. The maintenance interval for the GIS system is typically longer than for conventional switchgear.
Flexible Configuration: We understand that each substation has unique requirements. Therefore, our 40.5kV GIS panel is available in various configurations. Options can include different busbar arrangements, protection relay integrations, metering packages, and control system interfaces (local or remote).
Excellent Performance Parameters: The panel is designed to perform reliably under specified electrical conditions.

Benefits for Our Customers:

Space Optimization: The compact GIS design is ideal for urban substations, industrial plants, or any location where space is at a premium, allowing for higher power density in a smaller area.
Operational Reliability: With vacuum interruption and gas insulation, the system offers high availability and stability, which is crucial for continuous power supply in critical applications.
Reduced Lifecycle Cost: Lower maintenance requirements and long service intervals translate into reduced operational expenditures over the panel's lifetime.
Improved Safety Culture: The enclosed design significantly reduces the risk of accidental contact with energized parts, contributing to a safer working environment for substation personnel.
Adaptability: The customizable nature of the panel allows it to be tailored to fit into existing grid infrastructures or new projects seamlessly, accommodating specific control, protection, and monitoring needs.

Frequently Asked Questions (FAQ)

Q: What is the primary advantage of GIS over traditional AIS for indoor substations?
A: The main advantage is its compact size. GIS uses pressurized gas for insulation, which is far more effective than air, allowing the equipment to be much smaller. This saves significant floor space, which is often critical and expensive in indoor settings.
Q: Is the SF6 gas handling required for maintenance?
A: The GIS system is designed as a sealed unit. Under normal operation, no gas handling is required. Any major servicing that involves opening the gas compartment should only be performed by trained personnel following strict safety and environmental procedures, as SF6 is a potent greenhouse gas.
Q: Can this panel be integrated with digital substation automation systems?
A: Yes, it can. The panel can be equipped with modern numerical protection relays, smart meters, and communication interfaces (like IEC 61850) for integration into SCADA or other distribution automation systems, enabling remote monitoring and control.
Q: What is the typical delivery lead time for a custom-configured panel?
A: Lead times vary based on the complexity of the configuration and current production schedule. Generally, it ranges from 8 to 16 weeks after order confirmation and final design approval. We provide estimated timelines upon receipt of your detailed requirements.
Q: Do you provide installation supervision or commissioning support?
A: We can provide detailed installation manuals, drawings, and technical documentation. On-site supervision or commissioning support by our engineers is available as an optional service for an additional fee, which can be discussed during the project planning phase.
Q: What are the standard and optional ratings for the main busbar and circuit breaker?
A: Standard current ratings often range from 630A to 3150A, and short-circuit ratings from 25kA to 40kA. The 33kV VCB is standard, but the continuous current rating of the breaker is matched to the panel rating. All specific ratings are customizable based on your system's load and fault level studies.
Q: How does the Kyn61 design improve safety?
A: The Kyn61 metal-clad standard ensures that different high-voltage compartments (e.g., busbar, circuit breaker, cable) are separated by grounded metal partitions. This design contains any internal arc fault within its compartment, protecting adjacent sections and personnel.
Q: What kind of testing is performed on the panels before shipment?
A> Each panel undergoes a series of routine tests including power frequency withstand voltage tests, insulation resistance measurement, mechanical operation tests, primary injection tests for protection circuits, and functional checks of all control and signaling devices to ensure it leaves our factory in perfect working condition.
