Based on years of manufacturing experience, we designed the SRM16-12/24 Compact Inflatable Switchgear with a sealed gas insulation structure, compact design, and flexible configuration options to meet different project requirements.
For customers looking for a reliable medium voltage switchgear solution, our SRM16-12/24 switchgear provides a practical balance between electrical performance, installation convenience, and long-term operation reliability.
The Substation Use SRM16-12/24 Compact Inflatable Switchgear is a type of Medium Voltage Gas Insulated Switchgear designed for power distribution systems operating at 12kV and 24kV voltage levels.
In a power network, switchgear plays an important role in controlling, protecting, and distributing electrical energy. It connects incoming power sources with outgoing circuits and helps operators manage electrical flow safely.
The SRM16-12/24 Compact Inflatable Switchgear uses a fully sealed enclosure filled with insulating gas. Important electrical components are protected inside the sealed chamber, reducing the impact of dust, humidity, pollution, and external environmental changes.
Compared with traditional open electrical equipment, compact inflatable switchgear provides better environmental protection and requires less installation space. This makes it especially suitable for modern substations where space availability and operational reliability are important factors.
During our communication with customers from different industries, we found that traditional medium voltage equipment often faces several challenges:
Limited installation space in urban substations
Environmental influence caused by dust and humidity
Higher maintenance requirements
Need for safer operation and easier management
To solve these practical problems, we developed the SRM16-12/24 Compact Inflatable Switchgear with a compact structure and sealed insulation design.
Our goal is simple: provide customers with equipment that is easy to install, reliable during operation, and suitable for different power distribution environments.
The working principle of our compact inflatable switchgear is based on controlling and protecting medium voltage electrical circuits.
When electrical power enters the substation, the incoming cable connects with the switchgear unit. The internal switching devices control whether the circuit is connected, disconnected, or isolated.
During normal operation, the equipment allows electricity to flow safely through the distribution network. When a fault occurs, such as overload or short circuit, the protection system helps separate the affected circuit from the normal operating area.
This process reduces the risk of equipment damage and helps maintain continuous power supply for other parts of the network.
