Overview
The system is protected by a precision-engineered enclosure, providing exceptional resistance against mechanical impact
and harsh environmental stressors. Utilizing a hermetically sealed tank design, all primary live parts are shielded from external
contaminants to prevent oxidation. This 10kV Gas Insulated Ring Main Unit (RMU) is optimized for maintenance-free service,
significantly lowering the total cost of ownership over a 30-year lifecycle. Whether deployed in city centers or remote industrial
sites, our equipment guarantees consistent dielectric performance and adheres to the highest global safety standards. The modular
design allows for flexible expansion, while the integrated vacuum interrupters ensure rapid arc extinguishing and circuit safety.
This provides a future-proof solution for sustainable energy distribution in any climate.
Core Components and Features
The internal architecture centers on a heavy-duty metal gas compartment housing the main busbar system and switching elements.
Within this assembly, the Gas Insulated Switchgear Outgoing Unit utilizes high-end vacuum technology to ensure rapid arc quenching
and circuit protection. Each module is equipped with an intuitive spring-operated mechanism that supports both manual local control
and remote motorized automation for smart grid integration.The exterior structure is built from high-strength metal sheets treated
with electrostatic powder coating for superior corrosion resistance. Critical status indicators, including gas density monitors and position
displays, are integrated into the front control panel for clear visibility. Furthermore, the unit incorporates sophisticated micro-processor
based protection relays and smart sensors for thermal monitoring, ensuring the entire system operates within safe electrical parameters
even during peak load conditions in a High Voltage SF6 RMU configuration.
Design and Compliance
Design:
The equipment is built upon a rigid frame to ensure maximum mechanical stability during transport and site installation. This
10kV Ring Main Unit design undergoes rigorous internal arc testing (IAC) to guarantee personnel safety in the rare event of a fault.
By employing a sealed-for-life gas tank, the system effectively isolates all internal components from humidity, salt spray, and dust,
which are common failure points in traditional air-insulated designs. The heavy-duty enclosure further provides an additional layer
of protection, ensuring the switchgear remains operational even in vibration-prone or high-traffic industrial zones.
Compliance:
Every production unit is manufactured in strict accordance with IEC 62271-200 global standards for high-voltage switchgear. Our
High voltage 10kv GIS series is subjected to comprehensive quality audits, including mandatory partial discharge testing, mechanical
endurance verification, and lightning impulse withstand tests. The assembly process also aligns with international environmental
protocols, ensuring that SF6 gas handling is managed with maximum ecological care. This commitment to compliance ensures that
our switchgear meets the stringent entry requirements of power utility networks worldwide.
Key Advantages
Optimized Spatial Efficiency and Integration
The system features an ultra-compact architecture, making it the perfect choice for urban substations where every square meter
of real estate is valuable. By utilizing advanced gas insulation, we have significantly reduced the physical footprint compared to
traditional air-insulated equipment. This allows for seamless installation in crowded metropolitan basements, modular kiosks, or
compact industrial rooms without compromising the dielectric strength or operational safety of the power network.
Extreme Environmental Resilience
Encased in a durable Carbon steel 10kV RMU housing, the equipment is fully protected against salt spray and moisture, performing
flawlessly in coastal and offshore environments. The high-strength metal structure undergoes a rigorous multi-stage anti-corrosion
treatment, including electrostatic powder coating, to withstand high humidity and temperature fluctuations. This robust exterior
ensures that the internal primary circuit remains isolated from harsh atmospheric conditions and industrial pollutants.
Zero-Maintenance Philosophy
The hermetically sealed SF6 Gas Insulated switchgear eliminates the need for periodic cleaning of contacts or insulators, providing
a "fit-and-forget" solution for remote utility networks. All switching components are contained within a laser-welded stainless steel
gas tank, preventing oxidation and wear over a 30-year service life. This design drastically reduces long-term operational costs
and minimizes the need for on-site technical interventions in difficult-to-reach locations.
Integrated Operational Safety
The design incorporates a comprehensive mechanical interlocking system and a grounded metallic structure to ensure that maintenance
personnel are never exposed to live high-voltage components during switching operations. Each cabinet includes fail-safe "five-prevention"
logic to prevent manual errors. Furthermore, the pressure-relief flaps safely direct gases away from operators in the unlikely event of
an internal fault, maintaining the highest levels of workplace safety.

Application Scenarios
Metropolitan Grid Management
Our solutions are a staple for modern urban energy networks. The compact footprint allows for seamless installation in underground
vaults, compact residential kiosks, or crowded city centers where real estate is a premium. The feeders are engineered to manage
heavy power loads for high-rise commercial buildings and major transit hubs, ensuring a consistent and high-quality electricity
supply to the local community. By utilizing this Gas Insulated Switchgear Outgoing Unit, utility companies can expand grid capacity
in confined spaces without extensive civil works.
Renewable Energy Infrastructure
In the wind and solar sectors, the equipment acts as a reliable interface between power generation and the regional grid. The modular
design easily manages the intermittent power flows and frequent switching operations typical of renewable energy sites. While the
internal components ensure electrical stability, the rugged exterior shell protects the core against outdoor weather extremes, heavy
rain, and intense ultraviolet radiation. This durability makes it a preferred choice for remote solar farms and wind turbine step-up
substations.
Heavy Industrial Operations
Mining, oil and gas, and chemical plants require the rugged insulation of professional GIS solutions to maintain safety. The hermetically
sealed environment prevents flashovers in dusty, humid, or chemically aggressive atmospheres that would otherwise degrade critical
electrical components. This High voltage 10kv GIS provides a contamination-proof solution that minimizes the risk of short circuits,
ensuring zero production downtime and protecting expensive industrial machinery from power fluctuations.
Public Transportation Systems
Railway and metro operators utilize these units for critical traction power delivery and station distribution. The high reliability of the design
ensures that transport schedules are maintained by preventing unexpected power failures. The compact dimensions fit perfectly within
narrow trackside enclosures, subterranean tunnel substations, and elevated rail platforms, providing a versatile and robust energy solution
for modern high-speed transit infrastructures.
