Product Description
Ang Sabre Ring Main Unit (RMU) ay isang mataas na pagganap na medium-voltage switchgear na inihanda para sa secondary distribution networks hanggang 24kV. Mayroon itong SF6 gas insulation at sealed stainless steel tank, nagbibigay ito ng kahanga-hangang reliabilidad na may annual gas leakage rate ≤0.1% at 30-year service life. Magagamit ito sa non-extensible, extensible, at modular configurations, sumusuporta sa indoor/outdoor installation at naglalaman ng advanced safety, remote monitoring, at flexible expansion capabilities—ideal para sa utilities, commercial, industrial, at critical infrastructure applications.
Key Features
Superior Safety Protection: Nakakamit nito ang mechanical interlocks, padlocking facilities, at anti-reflex mechanisms upang maiwasan ang accidental operation. Fully internal arc-rated (ayon sa IEC standards) para sa maximum operator at pedestrian safety.
SF6 Gas Insulation: Ang sealed stainless steel tank na may SF6 insulation ay nagbibigay ng excellent dielectric performance, minimal maintenance, at resistance sa harsh environmental conditions.
Long Service Life & Reliability: Ang robotic welding para sa structural integrity, fully sealed oil tank (kung applicable), at high mechanical endurance components ay nagbibigay ng 30-year life expectancy.
Modular & Extensible Design: Ang non-extensible, extensible, at modular formats ay nagbibigay ng on-site expansion nang walang special tools o SF6 gas transfer, adapts sa evolving network needs.
Remote Monitoring & Control: Seamless integration sa Gemini 3 RTU para sa real-time monitoring ng gas pressure, partial discharge, at switch status. Sumusuporta sa remote operation at predictive maintenance.
Easy Installation & Maintenance: Ang factory-tested at pre-assembled modules ay nagbibigay ng mabilis na on-site deployment. Maintenance-free design na may accessible components at ≤4-hour single-bay replacement time.
Wide Environmental Adaptability: Gumagana sa -25℃ to 60℃ temperatures, hanggang 1000m altitude (without derating), at resistant sa pollution, sandstorms, at coastal salt spray.
Comprehensive Protection Options: Nag-aalok ng TLF (time limit fuses) o self-powered relay protection para sa overcurrent at earth faults.
Smart Grid Ready: Integrates sa SCADA systems at sumusuporta sa auto-changeover, auto-sectionalizing, at real-time network condition monitoring para sa smart grid applications.
Compact & Flexible Mounting: Freestanding o transformer-mounted designs na sumasaklaw sa limited spaces, may IP54 protection para sa outdoor use (no kiosk required).

Application Scenarios
Urban & Rural Medium-Voltage Distribution Networks: Ideal para sa branching at distributing power sa residential areas, suburban communities, at rural towns. Ang kanyang compact design ay sumasaklaw sa narrow installation spaces, habang ang low leakage at long service life ay nagbabawas ng grid operational costs. Ang extensible feature ay sumusuporta sa future network expansion.
Commercial & Public Facilities: Suitable para sa hotels, shopping centers, hospitals, office buildings, at data centers. Ang remote monitoring ay nagbibigay ng 24/7 stable power supply, at ang non-exposed live parts plus safety interlocks ay nagprotekta sa dense human traffic. Ang mabilis na installation ay nag-aadapt sa building construction timelines.
Renewable Energy Integration: Perfect para sa wind at solar power projects (utility-scale at distributed). Ito ay konektado sa renewable energy systems sa grid, stabilizes power output, at gumagana kasama ang energy storage systems. Ang kanyang environmental adaptability ay nakakatipon sa desert, plateau, at coastal conditions.
Critical Infrastructure & Transportation: Inilapat sa airports, tunnels, underground railways, at ports. Sumusunod sa mahigpit na safety standards (internal arc protection, seismic resistance) at sumusuporta sa remote operations at maintenance upang bawasan ang on-site disruptions. Resistant sa harsh environments tulad ng salt spray at sandstorms.
Industrial Plants: Nagbibigay ng lakas sa manufacturing facilities (automotive, mining, cement, petroleum), water/wastewater treatment plants, at industrial parks. Ang flexible protection options (TLF/relay) ay nag-aadapt sa industrial load demands, at ang modular expansion ay sumusuporta sa production capacity growth.
