Data of Switch-disconnector Type Ring Main Unit

1. About Product

I. Application and Function:

The XGW is a SF6 Gas Insulated Switchgear for 12/24 kV secondary distribution network. It is a compact unit combining all MV functional units to enable connection, supply and protection of one or two transformers on an open ring or radial network. With XGW switchgear as switching point, the effect of a fault on the network has been limited.

II. Structure

All MV function units, such as Switch-disconnector, Circuit-breaker, Fuse-switch combination, Bus Sectionalize, Cable connection and MV Metering module, can be integrated flexibly as customer request. XGW switchgear comprises 1 to 6 integrated functional units within the same metal enclosure.

III. Advantages of Design

1. Ensures personal safety

     1) Internal arc withstand in conformity with IEC 62271-200

     2) Visible earthing

     3) 3 position switchgear for natural interlocking

     4) Dependable position indicating devices.

     5) SF6 Gas Insulated

2. Insensitive to the environment

     1) 307 Stainless steel tank, degree of protection IP67

     2) Disconnectable, sealed, metallized fuse chambers

3. Approved Quality

     1) Conforms to national and international standards

     2) Design and production are certified to ISO 9001:2008

     3) Benefits from the experience accumulated from 20,000 functional units installed

world-wide

4. Economical

     1)From 1 to 6 functional units, integrated within the same metal enclosure for which insulation and breaking take place in SF6 gas

     2) Lifetime of 30 years

5. Maintenance Free

     1) Having maintenance free living parts, sealed for life

6. Rigorous, systematic checks

During the manufacture of each XGW, it undergoes systematic routine tests, the aim of which is to check quality and conform it

     1) tightness check

     2) filling pressure check

     3) opening and closing speed measurement

     4) operating torque measurement

     5) partial discharge check

     6) dielectric check

     7) conformity with drawings and diagrams

IV. Applied Standard: IEC60684, IEC60298, IEC60420, IEC60129, IEC60056, IEC60529, IEC56 

2. About Factory
