III. Design Specifications
-- Technical Description
The JHSRM16-12 series inflatable switchgear is installed on a galvanized sheet frame, with the switch unit inside an SF6 gas box made of corrosion-resistant and non-magnetic 3mm thick stainless steel plate.
SF6 gas tank is a "sealed pressure system" that can operate for 20 years under normal working conditions. The pressure of SF6 gas during normal operation is 0.15~0.4 bar. The gas box is equipped with a pressure release device, which ensures that gas can be released from the bottom or rear when the pressure is too high.
-- Switching unit
The load switch adopts a coaxial rotating double break method, which cooperates with the sliding plate through the same operating hole for kinetic operation. Therefore, the switch can only be in one of the three states of "closing, opening, and grounding" at any time, completely avoiding misoperation.
-- Operating mechanism
The operating mechanism of the switch is installed at the front of the air box and has undergone special processing to prevent rust and corrosion. It is convenient for manual operation and maintenance and easy to achieve electric operation.

At Jihui Electric Group Co., Ltd., we specialize in the research, development, manufacturing, and service of medium and low voltage power transmission and distribution equipment up to 35kV. Over the years, we have worked with power companies, engineering contractors, industrial enterprises, renewable energy developers, and infrastructure projects to provide stable and efficient electrical solutions.
With the rapid development of smart grids and modern energy systems, traditional switchgear can no longer fully meet the requirements of today's power distribution networks. Customers need equipment that is not only safe and reliable but also intelligent, easy to operate, and capable of remote management.
Our Smart Remote Control SRM MV Gas Insulated Switchgear is developed to meet these needs. By combining advanced gas insulation technology with intelligent remote control functions, our SRM MV Gas Insulated Switchgear helps users improve power distribution efficiency, enhance system safety, and reduce daily operation costs.
The product is designed for medium voltage applications and is widely used in smart grids, renewable energy plants, industrial power systems, commercial buildings, transportation facilities, mining projects, and urban infrastructure.
Smart Remote Control SRM MV Gas Insulated Switchgear is an intelligent medium voltage electrical distribution device that integrates switching, protection, monitoring, and communication functions into one compact system.
In simple terms, it acts as a smart control unit in a power distribution network. Electricity enters the switchgear from the main power source, and the internal switching components control the power flow to different loads or distribution lines.
When abnormal situations happen, such as short circuits, overloads, or equipment failures, the protection system can quickly disconnect the affected circuit to protect the entire electrical network.
Unlike conventional switchgear that mainly depends on manual operation, our Remote Control Medium Voltage Switchgear supports intelligent operation. Operators can monitor equipment status and perform control operations through communication systems without always being physically close to the equipment.
This feature is especially valuable for modern power systems where fast response, safe operation, and efficient maintenance are becoming increasingly important.
The working principle of our SRM MV Gas Insulated Switchgear is based on three key functions: electrical switching, insulation protection, and intelligent monitoring.
The main function of medium voltage switchgear is controlling electrical circuits. Inside the switchgear, components such as load switches, circuit breakers, busbars, and grounding switches work together to control the connection and disconnection of power circuits.
During normal operation, the equipment maintains stable power transmission. When maintenance is required or a fault occurs, the switching mechanism can isolate specific sections of the network to avoid wider power interruption.
Gas insulation technology is one of the important features of modern medium voltage switchgear.
Compared with traditional air insulated equipment, gas insulated switchgear uses sealed insulation space to improve electrical insulation performance and reduce the influence of external environmental factors.
This structure allows the equipment to maintain reliable operation in environments with dust, humidity, temperature changes, and limited installation space.
The smart remote control system is designed to collect important operating information through sensors and intelligent control modules.
The system can monitor electrical parameters and equipment status, including voltage, current, switching position, and operating conditions.
Through communication interfaces, this information can be transmitted to a control center or smart grid management platform.
For customers, this means:
Faster fault detection
Reduced manual inspection workload
Improved operation safety
Better maintenance planning
Higher power supply reliability
Modern cities and industrial facilities often face limited installation space. Traditional electrical equipment may require large rooms and complex installation conditions.
Our Smart MV Gas Insulated Switchgear adopts a compact structure that helps customers save installation space while maintaining excellent electrical performance.
The compact design makes it suitable for:
Urban substations
Industrial distribution rooms
Renewable energy stations
Commercial power systems
Infrastructure projects
Safety is always our primary consideration during product development.
The SRM MV Gas Insulated Switchgear is designed with reliable insulation, mechanical strength, and protection functions to ensure stable operation under different working conditions.
The sealed structure reduces the impact of dust and moisture, helping improve equipment service life and operational stability.
One of the biggest advantages of our product is intelligent remote operation.
For traditional switchgear systems, operators often need to travel to the installation site to check equipment status or perform switching operations.
With our intelligent MV Switchgear System, operators can receive equipment information remotely and make faster decisions.
This is especially useful for:
Large industrial factories
Remote renewable energy projects
Distributed power networks
Unattended substations
