GIS Ring Main Unit (GIS-RMU)

Gas-Insulated Medium Voltage Switchgear

 

Overview

 

The GIS Ring Main Unit (GIS-RMU) by Arian Kelid Pars is an advanced medium-voltage switchgear designed to provide safe, reliable, and maintenance-free operation for modern power distribution networks.

Manufactured under the technology license of MELCOS, the GIS-RMU utilizes Gas-Insulated Switchgear (GIS) technology to deliver exceptional operational reliability, compact dimensions, and superior electrical performance in demanding environments.

Available in 12 kV, 24 kV, and 36 kV configurations, the system is ideally suited for utility, industrial, commercial, and infrastructure applications.

 

Advanced GIS Technology

The GIS-RMU incorporates SF6 gas insulation, with all live components and busbars enclosed within a sealed gas-insulated tank.

 

This fully GIS-RMU sealed design provides:

* Superior dielectric performance

* Increased operational safety

* Reduced equipment dimensions

* High resistance to humidity and contamination

* Long service life

* Minimal maintenance requirements

 

Reliable Construction

The enclosure is manufactured from Stainless Steel 304, providing excellent corrosion resistance and long-term mechanical durability.

 

The GIS-RMU is designed for reliable operation under harsh environmental conditions including:

* High humidity

* Dust and industrial pollution

* Coastal environments

* Severe weather conditions

 

High-Performance Switching

The Arian Kelid GIS-RMU utilizes Vacuum Circuit Breaker (VCB) technology for fault interruption while maintaining the primary switching components inside the sealed SF6 gas compartment.

 

This combination provides:

* High operational reliability

* Excellent switching performance

* Long electrical endurance

* Maintenance-free operation

* Enhanced personnel safety

 

The GIS-RMU can be equipped with:

* Protection Relays

* Remote Terminal Unit (RTU)

* SCADA Communication

* Distribution Automation Functions

* Smart Grid Integration

The system supports real-time monitoring, remote control, fault management, and seamless integration with modern utility automation systems.

 

Cable Connections

Medium-voltage cable termination is provided using Plug-in Cable Connectors, ensuring safe, compact, and reliable cable installation.

 

The GIS-RMU is available in two configurations:

* Manual Operation

* Motorized Operation
