As a dedicated manufacturer with ISO9001 certification, Jinhua Dika Electrical Equipment Co., Ltd. specializes in providing reliable and high-performance medium voltage switchgear solutions. Our KYN61 MV 33KV Indoor SF6 Gas Insulated VCB Switchgear Panel is engineered for superior safety and operational efficiency in demanding power distribution networks. This panel integrates the proven reliability of vacuum interruption with the excellent insulating properties of SF6 gas, offering a compact, maintenance-friendly, and highly secure solution for your substation and industrial power control needs.
This switchgear panel is designed to meet the rigorous requirements of modern electrical infrastructure. The core of its design is the integration of a Vacuum Circuit Breaker (VCB) within an SF6 gas-insulated enclosure. This combination delivers several distinct advantages:
- Enhanced Safety and Reliability: The SF6 gas provides excellent dielectric strength, effectively quenching arcs and preventing internal flashovers. The sealed, pressurized design minimizes the risk of external environmental contamination, ensuring consistent performance and operator safety.
- Minimal Maintenance Requirements: Unlike air-insulated switchgear, the SF6 gas-insulated and vacuum-interrupted system operates with very few moving parts in contact and is not exposed to atmospheric conditions. This leads to significantly reduced maintenance intervals and lower lifecycle costs.
- Space-Saving Design: The high insulation capability of SF6 gas allows for a much more compact design compared to traditional air-insulated equipment. This is crucial for indoor substations or facilities where space is at a premium.
- Environmental and Operational Safety: The system is fully enclosed, containing the SF6 gas and any potential arc by-products within the tank. The vacuum interrupter ensures clean, fast, and reliable current interruption without expelling hot gases.
The technical specifications of our KYN61-40.5 panel are designed for robust performance. Below are some key parameters:
| Parameter | Specification |
| Rated Voltage (Ur) | 33KV / 36KV |
| Rated Frequency | 50Hz / 60Hz |
| Rated Normal Current (Ir) | 630A, 1250A, 1600A, 2000A, 2500A |
| Rated Short-Time Withstand Current (Ik) | 25kA, 31.5kA for 3s |
| Rated Short-Circuit Breaking Current (Isc) | 25kA, 31.5kA |
| Insulation Level (Power Frequency / Lightning Impulse) | 70KV / 170KV |
| SF6 Gas Pressure (20°C) | 0.04 MPa (Absolute) |
| Mechanical Life (VCB) | 10,000 operations |
| Standards Compliance | IEC 62271-100, IEC 62271-200 |
For clients, the benefits are clear and impactful. You gain a highly reliable protection system that minimizes unexpected downtime in critical operations like manufacturing plants, data centers, and utility substations. The long service life and low maintenance translate directly into reduced total cost of ownership. Furthermore, the modular and compact design simplifies installation and future expansion, offering flexibility for growing power demands.

Frequently Asked Questions (FAQ)
-
Q: What is the primary advantage of using SF6 gas insulation in this switchgear?
A: SF6 gas offers superior dielectric strength compared to air, allowing for a much more compact equipment design. It also provides excellent arc-quenching properties, enhancing the safety and reliability of the interruption process within a sealed environment. -
Q: Is this panel suitable for both 50Hz and 60Hz power systems?
A: Yes, the KYN61-40.5 switchgear panel can be configured and tested to operate reliably on both 50Hz and 60Hz electrical systems, making it suitable for a global client base. -
Q: How often does the SF6 gas need to be checked or refilled?
A: Due to its sealed-for-life design, the SF6 gas compartment is highly reliable and typically requires no maintenance or refilling under normal operating conditions throughout the switchgear's long service life. Gas pressure monitoring devices are provided for safety. -
Q: Can the rated current be customized for my project?
A: Absolutely. We offer a range of standard rated currents up to 2500A. Our manufacturing capability allows for customization to meet specific project current ratings, subject to technical feasibility. -
Q: What safety features are included to protect operators?
A: The panel features a robust interlocking system to prevent incorrect operation, an earthing switch for safe maintenance, pressure relief devices, and viewing windows. The "closed-door" operation capability keeps operators safe from live parts. -
Q: What is the typical delivery lead time for an order?
A: Lead time depends on the order quantity and configuration. For standard configurations, it is generally within 4-8 weeks. We provide accurate timelines upon receipt of your detailed specifications and can ship from major ports like Shanghai, Tianjin, or Ningbo. -
Q: Does this switchgear come with comprehensive testing reports?
A: Yes, each unit undergoes rigorous routine tests according to IEC standards, including mechanical operation, insulation, and primary injection tests. Relevant test reports are available upon request. -
Q: What after-sales support do you provide?
A: We provide detailed installation manuals, wiring diagrams, and offer technical support. For complex projects, on-site guidance from our engineers can be arranged. We are committed to supporting our clients throughout the product lifecycle.
