As a dedicated manufacturer with over a decade of expertise in electrical equipment, Jinhua Dika Electrical Equipment Co., Ltd. is proud to present our advanced Kyn61 MV Switchgear Panel with SF6 Insulated 33KV Circuit Breaker. Engineered for reliability and safety in demanding medium-voltage applications, this panel represents our commitment to delivering robust power distribution solutions. Our focus on stringent quality control, evidenced by our comprehensive management system certifications, ensures that every unit meets high-performance standards for global industrial and utility clients. This switchgear is designed to provide superior protection, enhance operational continuity, and minimize maintenance requirements for your critical electrical infrastructure.
This Kyn61 metal-clad switchgear integrates a 33KV SF6 gas-insulated circuit breaker, offering a compact, safe, and maintenance-friendly solution for indoor installations. The SF6 gas provides excellent dielectric and arc-quenching properties, ensuring reliable interruption of fault currents and enhancing the overall safety of the installation. The panel's robust construction and logical compartmentalization protect personnel and extend equipment life.
- Advanced SF6 Insulation: Utilizes sulfur hexafluoride gas for superior insulation and arc extinction. This results in a more compact design compared to air-insulated alternatives, reduced risk of internal flashovers, and consistent performance over a wide range of environmental conditions.
- Enhanced Safety Features: The metal-clad, compartmentalized design strictly separates the circuit breaker, busbars, and cable connections. This ensures operator safety during maintenance and prevents the propagation of internal faults. Equipped with mechanical and electrical interlocks to prevent incorrect operations.
- High Reliability & Durability: Built with high-quality components and a rigid structure to withstand the mechanical stresses of circuit breaker operation and potential short-circuit forces. The sealed SF6 system requires minimal maintenance, ensuring long-term operational reliability.
- Flexible Configuration: The panel can be customized with various protection relays, metering devices, and communication interfaces (optional) to integrate seamlessly into modern SCADA and smart grid systems, providing real-time monitoring and control.
- Ease of Maintenance: The withdrawable design of the circuit breaker allows for easy inspection, testing, and replacement without de-energizing the entire busbar system, significantly reducing downtime.

Frequently Asked Questions (FAQ):
Q1: What is the primary advantage of using SF6 gas insulation in this switchgear?
A1: SF6 gas offers exceptional dielectric strength and superior arc-quenching capabilities. This allows for a more compact panel design, enhances operational safety by effectively suppressing internal arcs, and reduces maintenance needs compared to air-insulated switchgear.
Q2: Is this Kyn61 panel suitable for outdoor installation?
A2: The standard Kyn61 design is typically intended for indoor installation. For outdoor applications, a proper housing or shelter is required to protect the equipment from direct weather exposure. We can provide guidance on suitable enclosure solutions upon request.
Q3: Can the circuit breaker's rated current and breaking capacity be customized?
A3: Yes. While common ratings are 1250A, 1600A, and 2000A with breaking capacities of 25kA or 31.5kA, we can customize these parameters according to your specific system design and fault level requirements. Please provide your detailed specifications for a tailored solution.
Q4: What kind of maintenance does the SF6 gas system require?
A4: The SF6 system is sealed for life under normal operating conditions, requiring very little maintenance. Periodic checks for gas pressure and density are recommended as part of a routine maintenance schedule. The circuit breaker's mechanical operating mechanism may require lubrication and inspection at intervals specified in the manual.
Q5: Does the panel come with protection relays and meters?
A5: The panel is designed to accommodate various protection and metering devices. These can be specified and supplied as part of the package based on your project needs. We offer a range of compatible digital and electromagnetic relays, as well as metering units.
Q6: What are the delivery lead times for this product?
A6: Lead times vary based on order quantity, configuration complexity, and current production schedule. Generally, standard configurations can be delivered within 4-8 weeks after order confirmation. We strive to provide accurate timelines upon receipt of your inquiry.
Q7: What standards does this switchgear comply with?
A7: Our Kyn61 switchgear is designed and manufactured in compliance with international standards such as IEC 62271-200 for AC metal-enclosed switchgear and relevant Chinese GB standards. Specific certification details can be provided upon request.
Q8: Do you provide technical support and documentation?
A8: Absolutely. We provide comprehensive product documentation, including wiring diagrams, technical manuals, and test reports. Our engineering team is available to offer technical support during the specification, installation, and commissioning phases.
