The switchgear adopts a modular unit design and can be configured according to different applications. It consists of two main types: fixed unit combinations and expandable units, meeting the flexible usage requirements for compact switchgear in various substations.

The SRM16-12 Fully Insulated, Fully Enclosed Ring Main Unit (Standardized) is a completely sealed system where all live parts and switches are enclosed within a stainless steel shell. The entire switchgear is unaffected by external environmental conditions, ensuring operational reliability, personnel safety, and maintenance-free operation. By selecting expandable busbars, any combination can be achieved, enabling full modularization. The expandable busbars are safely insulated and shielded, guaranteeing high reliability and safety.

The SRM16-12 gas-insulated switchgear can also provide integrated automation solutions, forming the concept of intelligent switching and minimizing on-site installation and commissioning work.

The SRM16-12 Fully Insulated, Fully Enclosed Ring Main Unit (Standardized) is divided into non-expandable standard configurations and expandable standard configurations. It offers exceptional flexibility due to its combination of full and semi-modular capabilities and its own expandability.

The SRM16-12 Fully Insulated, Fully Enclosed Ring Main Unit (Standardized) complies with GB standards. Its design service life under indoor conditions (20°C) exceeds 30 years.

Main Product Features:

The fully insulated, fully sealed (standardized) ring main unit metal-enclosed switchgear uses SF6 gas as the arc-extinguishing and insulating medium.

◆ Reliable Operation
The switchgear is fully sealed and fully insulated; busbars, switches, and live parts are completely enclosed in a stainless steel shell. The chamber is filled with SF6 gas at 1.4 bar, achieving a protection rating of IP67. The entire switchgear is completely unaffected by external environmental conditions, ensuring normal operation even under special circumstances like temporary flooding. The product is maintenance-free for life.

◆ Safe Operation
The switchgear is equipped with a comprehensive interlocking system to prevent misoperation,彻底 preventing personal injury and operational faults caused by human error. All switchgear units have reliable safety pressure release channels, ensuring operator safety even under special circumstances.

◆ Flexible solutions
The switchgear is divided into two types: fixed unit combinations and expandable unit combinations. They are typically front-connected but can also be configured for side cable entry or side expansion depending on the installation location. The compact cabinet size facilitates easy installation and is suitable for spaces with limited room or poor environmental conditions. The switchgear can be equipped with motorized operating mechanisms, remote control, and monitoring devices according to user requirements.

◆ Wide Application
It features high feeder capacity and a small footprint, making it suitable for various application needs.
