Product details
Overview
Our company's SRM6-12 inflatable SF6 metal enclosed fully insulated series of faulty switchgear has passed the type test of the National High Voltage Electrical Testing Center and been listed as a Zhejiang Province science and technology product in the Zhejiang Province Science and Technology Project. The product is widely used in 10kV/6kV distribution systems and is a switch product for various urban and rural users' power transformation and distribution systems.
The switchgear adopts a modular unit mode, which can be combined according to different purposes; There are two main types of fixed unit combinations and expandable units, which meet the flexible use needs of various substations for compact switchgear.
The SRM6-12 inflatable mesh cabinet is a sealed system, with its charged components and switches enclosed within a stainless steel body. The entire switch assembly is not affected by external environmental conditions, thus ensuring reliable operation and personal safety. And it has achieved maintenance free operation. By selecting expandable busbars, any combination can be achieved to achieve full modularity. Expanding busbar safety insulation and shielding enhances reliability and safety. The SRM6-12 inflatable ring main unit can also provide a TV based automation solution, forming the concept of intelligent switches and reducing on-site installation and debugging workload.
The SRM6-12 inflatable ring main unit is divided into non expandable standard configuration and expandable standard configuration. Due to its combination of full and half modules and self scalability, it has flexibility.
SRM6-12 inflatable damaged mesh cabinet complies with GB standards. The design lifespan for operation under indoor conditions (20 ℃) exceeds 30 years.

Product model main features
♦operation safety
♦ We can provide users with special security protection through the following security measures:
◊Integrated three station load switch
◊The circuit breaker uses a load switch instead of an isolation switch, which is safer and more reliable
◊ One side fully enclosed design provides protection against external contact
◊Mechanical interlocking that meets the five prevention requirements
◊ The live display can provide live indication for incoming and outgoing lines
♦Reliable operation
◊Fully enclosed design, the 10kV switch and busbar live parts are sealed in a 3mm stainless steel welded gas box; Equipped with silicone rubber cable plugs to achieve full insulation and sealing of cable heads, thus avoiding external environmental influences such as dust, moisture, and small animals
Spring energy storage operating mechanism, which can be manually or electrically operated
◊ Panel simulation line diagram provides switch position indication
◊The cabinet is made of galvanized sheet metal, with surface electrostatic spraying to enhance corrosion resistance
◊ Safety pressure range of SF6 gas inside the pressure gauge monitoring box
♦Economic viability
◊Maintenance free
◊ Highly reliable
◊ The service life can reach 20 years
♦ Flexible plan
◊ Multiple entry methods, capable of achieving left, right, up or forward lines
◊ Multiple combination methods, allowing for arbitrary combinations between units
◊ Using insulated busbars, it can achieve front and rear cabinet connection or left and right cabinet connection
◊ Flexible design scheme
♦ Widely used
◊ The feeder line has a large capacity and small footprint, suitable for various application needs
Design Notes
♦Technical Description
The SRM6-12 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.
♦ SWITCH 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, which has undergone process treatment, rust prevention, and is convenient for manual operation and maintenance. It is also easy to achieve electric operation.
