As a dedicated manufacturer with ISO9001 certified quality management, Jinhua Dika Electrical Equipment Co., Ltd. specializes in delivering reliable and high-performance electrical solutions for global power infrastructure. Our Outdoor Tank-Type SF6 Gas Circuit Breaker represents a cornerstone of modern, safe, and efficient power distribution and protection systems. Engineered for demanding outdoor environments, this circuit breaker is supplied complete with comprehensive documentation, including the Mill Test Report (MTR) and detailed Operation Manuals, ensuring full transparency, ease of installation, and long-term operational confidence for our clients worldwide.

This circuit breaker is designed to isolate and protect electrical circuits from damage caused by overload or short circuit. Its robust tank-type construction houses the advanced SF6 gas insulation and arc-quenching system, making it an ideal choice for utility substations, industrial plants, and renewable energy farms.

Core Features & Technical Advantages:

Superior Dielectric & Arc-Quenching Properties: Utilizing Sulfur Hexafluoride (SF6) gas as the insulating and arc-quenching medium, this breaker offers exceptional performance. SF6 has high dielectric strength, enabling compact design, and excellent thermal conductivity for efficient heat dissipation during current interruption.
Robust Outdoor Construction: The tank-type housing is built from high-grade, corrosion-resistant materials, designed to withstand harsh weather conditions including rain, snow, dust, UV radiation, and wide temperature fluctuations, ensuring long-term reliability.
Complete Documentation for Quality Assurance: Every unit is accompanied by a Mill Test Report verifying the material properties and a full set of Operation & Maintenance Manuals, providing clear instructions for installation, commissioning, and routine service.
High Reliability & Low Maintenance: The sealed SF6 gas system is virtually maintenance-free for extended periods. The self-contained design minimizes external environmental influences on its operating mechanism.
Flexible Configuration & Compatibility: Our breakers can be customized to match various system requirements, including different rated voltages, currents, and short-circuit breaking capacities. They are designed to be compatible with common international standards.

Key Technical Specifications (Typical Range):

Parameter	Specification / Range
Rated Voltage (Ur)	12kV, 24kV, 36kV, 40.5kV, 72.5kV (Customizable)
Rated Normal Current (Ir)	630A, 1250A, 1600A, 2000A, 2500A, 3150A
Rated Short-Circuit Breaking Current (Isc)	20kA, 25kA, 31.5kA, 40kA (or as required)
Interrupting Medium	SF6 Gas
Operating Mechanism	Spring-operated or Motor-operated (optional)
Standards	IEC 62271-100, ANSI C37.04, GB/T 1984 (Design compliant)

Benefits for Your Operations:

Enhanced System Safety: Provides reliable protection for personnel and equipment by quickly and safely interrupting fault currents.
Reduced Downtime: High reliability and low maintenance needs contribute to increased system availability and operational continuity.
Space Optimization: The compact design of SF6 technology allows for efficient use of space in substation layouts.
Lifecycle Cost-Effectiveness: The combination of durability, minimal maintenance, and long service life results in a favorable total cost of ownership.
Global Project Support: With extensive export experience to markets across North America, Europe, Asia, Africa, and Oceania, we understand diverse grid requirements and can provide suitable technical support.

Frequently Asked Questions (FAQ):

Q: What is the significance of the Mill Test Report (MTR) included?
A: The MTR is a certified document from the material manufacturer. It provides verifiable data on the chemical composition and mechanical properties (like tensile strength) of the key metallic components (e.g., tank, contacts) used in the breaker, ensuring they meet the specified grade and quality standards for reliable performance.
Q: How does SF6 gas compare to other insulating mediums like vacuum or oil?
A: SF6 gas offers a higher dielectric strength than air or oil, allowing for more compact breaker designs. It provides excellent and consistent arc-quenching performance, especially at higher voltages, and is contained within a sealed system, reducing fire risk compared to oil and requiring less maintenance than air-blast types.
Q: Is special handling required for the SF6 gas?
A: Yes, SF6 is a regulated gas. While the breaker is sealed for life, handling during major servicing or at end-of-life requires procedures to prevent release, following environmental regulations. Our manuals include guidance, and trained personnel should perform such tasks.
Q: Can this circuit breaker be integrated with existing SCADA or protection relay systems?
A: Yes. The operating mechanism typically includes auxiliary contacts (normally open/closed) for remote signaling of breaker status (open/closed). It can be easily interfaced with modern protection relays and SCADA systems for automated control and monitoring. Specific interface requirements can be discussed.
Q: What is the typical delivery lead time for a customized order?
A: Lead time depends on the customization level and order quantity. For standard specifications, it is generally shorter. We provide estimated timelines upon receipt of your detailed requirements to ensure planning alignment for your project.
Q: Do you provide installation supervision or commissioning support?
A: While detailed installation instructions are provided in the manuals, on-site technical support or supervision services are available upon request for an additional fee, ensuring optimal setup and initial operation.
Q: What are the main application areas for this type of circuit breaker?
A: It is primarily used in outdoor high-voltage applications such as transmission and distribution substations (both incoming and feeder protection), large industrial complexes, mining operations, and connecting points for wind or solar farms to the main grid.
Q: How is the quality control process ensured during manufacturing?
A: Our ISO9001 certified quality management system governs the entire process, from material inspection (verified by MTRs) and component assembly to rigorous final testing, including mechanical operation, dielectric withstand, and contact resistance tests, before shipment.
