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 focus on the research, development, manufacturing, and service of medium and low voltage power transmission and distribution equipment up to 35kV. For many years, we have been working with power companies, engineering contractors, industrial customers, renewable energy developers, and infrastructure projects to provide safe and reliable electrical solutions.
With the continuous expansion of power networks, more projects are being built in challenging environments such as high-altitude areas, remote regions, mountain zones, and areas with large temperature differences. These locations create higher requirements for electrical equipment because low air pressure, harsh weather, and difficult maintenance conditions can affect normal operation.
Our High Altitude Adaptable SRM SF6 Inflatable Switch Cabinet is specially designed for these demanding applications. By combining SF6 gas insulation technology, compact cabinet structure, and reliable medium voltage switching performance, our product helps customers build stable power distribution systems in high-altitude and complex environments.
The SRM SF6 Inflatable Switch Cabinet is widely used in power grids, renewable energy plants, industrial facilities, mining projects, urban infrastructure, and other medium voltage applications. It provides customers with a practical solution where safety, reliability, and environmental adaptability are equally important.
The High Altitude Adaptable SRM SF6 Inflatable Switch Cabinet is a Medium Voltage Gas Insulated Switchgear designed to maintain stable electrical performance in high-altitude environments.
In simple words, it is a smart electrical control cabinet that manages the distribution and protection of medium voltage power. It can connect, disconnect, and protect electrical circuits while reducing the influence of outside environmental conditions.
Traditional air insulated switchgear depends heavily on surrounding air conditions for insulation. However, when equipment is installed at high altitudes, the air density becomes lower, which may affect electrical insulation distance and equipment design requirements.
Our SF6 gas insulated structure solves this challenge by using sealed insulation technology. The internal gas environment provides stable insulation performance, allowing the equipment to operate reliably even in areas with reduced atmospheric pressure.
For customers working in high-altitude regions, this means fewer operation concerns, better equipment stability, and improved power supply reliability.
High-altitude environments are different from normal installation locations. As elevation increases, several factors can influence electrical equipment performance.
Lower air density affects external insulation conditions
Large temperature differences may influence equipment materials
Remote locations make maintenance more difficult
Harsh weather requires stronger environmental protection
Because of these challenges, ordinary medium voltage equipment may not always be the best choice. Power systems in these areas require equipment with better adaptability and stable operation capability.
Our High Altitude Medium Voltage Switchgear is developed based on these real application needs. We consider environmental conditions during product design to ensure reliable performance in different regions.
The working principle of our SRM SF6 Inflatable Switch Cabinet is based on electrical switching, insulation protection, and fault control.
The main purpose of the switch cabinet is to control medium voltage power flow. Inside the cabinet, components such as load switches, circuit breakers, grounding switches, and busbars work together to manage electrical connections.
During normal operation, the equipment allows electricity to pass safely through the distribution system. When maintenance is required or a fault occurs, the switching mechanism can isolate the affected section to protect other equipment.
The most important feature of this product is the SF6 gas insulation system.
SF6 gas has excellent electrical insulation performance. Inside the sealed cabinet, it creates a stable insulation environment around electrical components.
This structure helps reduce the influence of external conditions such as:
High altitude environment
Dust and pollution
Humidity changes
Outdoor temperature variation
As a result, the equipment can maintain stable operation in locations where traditional switchgear may face more challenges.
Electrical safety is always our priority.
The SRM SF6 Inflatable Switch Cabinet includes protection functions that help prevent damage caused by abnormal electrical conditions such as overload and short circuit.
By quickly isolating fault areas, the equipment helps protect transformers, cables, and other connected electrical devices.
The biggest advantage of this product is its ability to adapt to complex environments.
Whether installed in mountain areas, high-altitude power stations, remote energy projects, or industrial sites with demanding conditions, our switch cabinet provides stable performance.
The sealed SF6 insulation structure reduces dependence on external air conditions, making it suitable for areas with special geographical conditions.
Installation space is often limited in substations and energy projects.
Our SF6 gas insulated switch cabinet adopts a compact design, helping customers reduce installation space requirements while maintaining reliable electrical performance.
Compared with traditional air insulated equipment, the compact structure provides more flexibility for project planning.
Medium voltage equipment must operate continuously and safely for many years.
Our product is designed with stable mechanical structure, reliable insulation performance, and strong electrical capability to support long-term operation.
For remote areas, maintenance efficiency is very important.
Because the main electrical components are protected inside a sealed cabinet, the equipment is less affected by dust, moisture, and external pollution.
This helps reduce inspection frequency and improves operation efficiency.
At Jihui Electric, we do not only manufacture electrical cabinets. We focus on creating products that solve real problems for customers.
