Product Description

1. General
 
SRE6 SF6 Gas Insulated Switchgear (RMU) is a new type of SF6 GIS of medium-voltage ring modularized extensible switchgear, Safe-ring-extend-SF6, abbreviated as SRE6.
 
All SRE6 SF6 Gas Insulated Switchgear are in accordance with the requirements of IEC 60298 and GB 12706 and pass the type tests specified by the Xi'an High Voltage Apparatus Research Institute. Their service lives exceed 20 years.
 
 
2. Main characteristic
 
 
Safe, reliable and stable
?Safety: 3-position load switch may be interlocked, switch positions are indicated legibly; in the case of standard configuration, the function of voltage presence indication is possessed to ensure safety. Reliable gas duct and the design of arc fault prevention, passing the 20 kA internal arcing type test.
?Stability: Programmingdesign, normalized process control, and modular combination ensure stable quality.
 
All insulation, full enclosure, free maintenance
?All high-voltage live parts are fully enclosed in the SF6 Gas Insulated Switchgear, and the degree of protection is up to IP67. The whole switchgear is free from external environmental impact, which realizes all insulation, full enclosure, and maintenance free.
 
Arbitrary assembling, unrestricted extensibility
?A split box type is used, or an integrated box of multiplex unit may also be realized. Free assembling of all modular units meets the requirement of different customers. Unit modules may be extensible in situ flexibly, and a variety of MV substations may be constructed for different requirements. Modular design, freely extensible combination.
 
4,Intelligent integration
?An intelligent distribution network system is provided for realization of self-contained protection, remote control, monitoring, fault handling, etc. Integrated installation and debugging in the plant; minimizes the field work load.
