XGN15 (DXG) -12 indoor AC high-voltage-type sulfur ring in order to counter the new generation of sulfur hexafluoride load switch as the main switch and the entire cabinet air insulation for power distribution automation, not only compact but also expansion of the metal-enclosed switchgear.
XGN15-12 small-scale switching of fixed equipment, is the CEC Longyuan Electric Power Company of the Commonwealth by the State organization commissioned a joint design of a new generation of small-scale urban and rural power equipment, with high-grade, small size, parameters of the whole, low-cost, less maintenance and so on.
The ring counter has a simple structure, flexible operation, reliable interlocking characteristics of a variety of applications, different users are able to provide satisfactory solutions. The latest sensor technology and the use of protection relays, together with the advanced technical performance and the Light of Hope
Live assembly program, you can fully satisfy the requirements of the ever-changing market.
This series of ring counters following IEC standards:
IEC60298 metal exchanges closed distribution devices and control equipment (1kV-52kV)
(1990), Am1 (1994)
IEC60694 specifications commonly used high-voltage switchgear and control equipment (1996)

IEC60420 general exchange of load switch - fuse combinations (1990)
Switchgear IEC60529 provides protection level (IP standard)
This series of ring counters of the following national standards:
GB 3906 3 ~ 35kV AC metal-enclosed switchgear
GB/T11022 high voltage switch equipment and control equipment to share the technical requirements of standards
The exchange of high-voltage load switch GB/T16926 - fuse combinations
GB 3804 3 ~ 63kV AC high voltage load switch
Inside of the electrical components are in line with their respective standards.
Ring counters for three-phase AC 50Hz, rated voltage of 12kV indoor switchgear. Widely used in industrial and civil cable ring network and power supply terminal.
Especially suitable for small-scale secondary distribution points, opening and closing, the industrial and mining enterprises, urban districts, airports, railways, tunnels, power systems, such as high-rise building as a receiving and distribution of electric energy use.
Ring counters closed metal sheathed, insulated air inside. Connection with a terminal substation and adapt to the wire loop power supply.
This series of ring counter equipment specification parts used: selection of circuit breakers (vacuum or SF6 type), grounding switches, fuses, instrument transformers, the secondary instrument, through a combination of these components to a broad range of design options to meet the requirements. According to the needs of low-voltage boxes can be created. Products are reliable mechanical interlock devices to meet the "five-anti" functional requirements.
The main switch can be selected: DLF-12 sulfur hexafluoride load switch, FLN36-12D-type sulfur hexafluoride load switch, vacuum circuit breakers, etc.; ABB companies can also choose SFL-12/24 original sulfur hexafluoride load-type switch, HAD / us-based or sulfur hexafluoride circuit breaker VD4-S-type, such as vacuum circuit breakers.
