1.Modular Unit Design:Features fixed unit combinations and expandable units, allowing customization based on specific operational requirements.
2.Fully Sealed System:Ensures protection for live components against environmental factors, enhancing durability.
3.Expandable Busbars:Offers safely insulated and shielded busbars that allow full modularity, enabling various configurations.
4.Compliance with Standards:Meets GB standards, ensuring quality and reliability.
5.Long Design Lifespan:Designed for a lifespan of over 30 years under indoor operating conditions (20℃), reflecting its durability and reliability.
1.Fully Sealed Gas Insulation, Compact & Maintenance-Free: Utilizes a fully sealed stainless steel gas chamber with SF6 or eco-friendly gas as the insulation and arc-quenching medium, achieving fully insulated and sealed switchgear. Compact structure, with a volume only 1/3 to 1/2 of traditional air-insulated switchgear. Truly maintenance-free for life, especially suitable for space-constrained, harsh environments, and applications demanding high reliability.
2.Modular Assembly, Flexible Combination: Based on standardized modules like C, F, V, Cb , it can be flexibly assembled into various schemes such as Ring Main Units (RMU), incoming/outgoing feeder units, and metering units. Supports expandable busbars for infinite extension, meeting diverse primary wiring needs.
3.Safe & Reliable for All Conditions, Long-Life Design: All live parts are sealed within the pressurized enclosure, unaffected by external environmental factors like dust, moisture, condensation, contamination, or small animals. High mechanical life up to 5000 operations, designed service life over 30 years, ensuring long-term stable grid operation.
4.Comprehensive Intelligent Interfaces, Easy Upgrade: Pre-equipped with standard PT/CT interfaces and secondary wiring space, allowing easy addition of intelligent devices like microprocessor protections, FTU/DTU, and communication managers. Supports "Three-Remote" functions for seamless integration into distribution automation systems.
5.High-Standard Environmental & Safety Compliance: Complies with GB standards. Uses dry air or a slight positive pressure design to prevent internal condensation. If SF6 gas is used, equipped with density relays and pressure gauges to ensure controlled leakage risk. Optional laser-welded gas chambers further enhance sealing reliability.
1.Solution Customization & Drawing Design: Provides free single-line diagrams, secondary schematic diagrams, cabinet arrangement plans, and foundation requirement drawings based on the user's distribution network diagram and site conditions.
2.Factory Integration Testing & Training: Completes all gas tightness, power frequency withstand voltage, partial discharge, mechanical characteristic, and interlock tests before delivery, providing a full set of reports. Offers specialized training for user O&M personnel on product structure, operation, and intelligent terminal commissioning.
