Basic Introduction to SRE-SF6 Chengji Electric Ring Main Unit

Shanghai Chengji Electric Ring Main Unit is a new type of SF6 gas insulated medium voltage ring network modular expansion switchgear Safe Ring extend-SF6, abbreviated as SRE-SF6.

The SRE-SF6 ring main unit is a module that completely seals all live components inside the SF6 main box. The entire switchgear is not affected by external environments, ensuring the safe and reliable operation of the equipment. It achieves full insulation, full sealing, and maintenance free. Modules can be expanded through built-in busbars to achieve any combination, saving time and reducing investment. The SRE-SF6 ring main unit also provides a solution for future smart grid systems.

SRE-SF6 ring main unit complies with IEC60298 and GB12706 standards, and has passed the type test of Xigao Institute, with a service life of over 20 years.

　　Product Features

　　Safe, reliable, and stable

Safety: The three station load switch realizes mutual interlocking, with clear switch position indication and standard point indication function to ensure safety;

Reliable pressure relief channel, anti arc fault design, passed 20kA internal combustion arc type test;

Stability: Programmed design, standardized process control, modular combination ensure stable quality.

　　Fully insulated, fully enclosed, maintenance free

All high-voltage live components are completely enclosed in SF6 boxes, with a protection level of IP67. The entire switchgear is not affected by the external environment, achieving full insulation, full enclosure, and maintenance free.

　　Any combination, infinite expansion

It can be divided into boxes or shared by multiple units, freely combining various module units to meet different customer requirements. Flexible expansion of unit modules can be carried out on-site, making it easy to build various medium voltage substations with different requirements. Modular design, free expansion and combination.

　　intelligent integration

An intelligent distribution network system that can provide supporting functions such as protection, remote control, monitoring, and fault handling. It can be installed and debugged in an integrated manner within the factory, minimizing on-site workload.

　　SRE-SF6-AL

　　Product Features:

Scalable type: Through the built-in expansion insulator box busbar connector, multiple unit sharing can be achieved, and multiple module units can be freely combined for unlimited expansion.

Non expandable type: When the unit module does not require expansion, there is no need to install a sleeve.

Standard conduit type: can be connected to external cables.

　　SRE-SF6-BL

　　Product Features:

Scalable type: It can be connected to other SRE-SF6-B series switches on the side of the switchgear as needed. (The V module unit needs to increase the width by 50mm on the expansion side)

Non expandable type: When one side does not require expansion, there is no need to install a sleeve.

Standard conduit type: can be connected to external cables.

Other modules are customized according to user requirements.
