    Introduce：NxIEP AC Metal Switchgear is a new generation of smart medium voltage switchgear It adopts international advanced technology and workmanship, and has been passed XIAN High Voltage Electric Apparatus Insititute's Type Tests.The switchgear adapts to power plants, substation,large enterprise and large high voltage electric facilities.
Description：

I. Description

As a new generation of indoor medium voltage switchgear,NxIEP is mainly used to distribute electric power with voltage from 3.6kV to 12kV. It also can perform control,protection, and supervising functions on circuits.The rated current is as high as 4000A.NxIEP comform to all relevant electric apparatus standards.

II.Feature

1.Compact enclosures, space saving and cost saving

2.Full ranges, the electric factor reach 4000A,50kA at its highest

3.Central-location design, equiped with Simens 3AH2 vacuum circuit breacker;VD4、VEP、VS1、EV12 are available according to customer requirements

4.Can configure arc protecting system, ensure the safety of switchgear and expensive main trabsformer

5.Can equip contactor temperature monitoring system,which can real-time supervise the temerature of joint part of active and static contactor

6.The main bus is supported by wallbushing and sub-bus, no extra support needed for insulator

7.High reliable protecting locking devices

8.Convenient operation and maintenance; the switchgear can be placed against wall or two switchgears can be placed back-to back

9.Equiped with close grounding breaker which can quickly breack shortcircuit

10.the hand trolly can select racker-operation and electric operation

11.the equipment and hand trolly have reliable grounding devices
