IHM-6500-AR series auto recloser is a new generation of product developed to satisfy the demand of switchgear for rapid developing smart distribution network. IHM-6500-AR recloser and IHM-6500-LBS line sectionalizer cooperate to realize automatic isolation of the faulty section of the distribution line and achieve the feeder automation function. Reclosers are installed at the head of distribution lines, the head of large branches or the incoming side of users to achieve rapid local isolation of faults, and cooperating with sectionalizers to achieve sectional isolation to reduce the scope of power outages. It is widely used in ring power supply lines, radioactive lines, branch lines and end-user feeders. Reclosers can connect with SCADA to complete fault location, safe power supply transfer control, and load management etc. 

The IHM-6500-AR Auto Recloser is equipped with a multi-interface and multi-protocol communication system, catering to both debugging and remote control needs for efficient data interaction in different scenarios. Specifically, it has:
1.Front Panel RJ45 Ethernet Port: IEC104 protocol for debugging; 

2.Rear Panel RS232 & RS485/232 Serial Port: IEC101/DNP3.0/Modbus for remote; 

3.Rear Panel RJ45 Ethernet Port: IEC104/DNP3.0/Modbus for remote.

INHE's Auto Sectionalizer adopts SF6 dielectric insulation technology. It works together with recloser to further improve feeder reliability. It can be used in the main line of distribution network, branch line or at user boundary. It detects fault and automatically isolates faulty sections of a network in conjunction with recloser operation. It also senses current and voltage to count the number of recloser trip operations. When the preprogrammed number of recloser operations is reached, the sectionalizer opens during the recloser dead time to isolate the downstream fault.

INHE's Auto Sectionalizer can be used on overhead distribution lines for all voltage classes rated up to 40.5kV(12kV, 24kV, 40.5kV) at 50/60Hz power system.

IHM-RMU6 series medium voltage switchgear (24kV and below voltage level) is a SF6 insulated fully sealed maintenance-free medium voltage switchgear. Each functional unit is modular design with flexible combination and expansion of unit cabinet and shared cabinet, meeting the safe use requirements of medium voltage distribution system of 24kV and below.

IHM-6600-KYN28 series indoor metal-clad withdrawable switchgear is a complete power distribution device for rated voltage up to 24kV(12kV, 24kV), 3-phase AC 50/60Hz,single-bus and single-bus sectionalized system.

It is mainly used for power transmission of middle/small generators in power plants; power receiving, transmission for substations in power distribution andpower system of factories, mines and enterprises, and starting of large high-voltage motor, etc.,so as to control, protect and monitor the system. The switchgear can be used with VD4 from ABB and VB2 from GE, etc., it is a power distribution device with good performance.

IHM-RMUA Air Insulated Switchgear adopts dry air as the insulating medium. The isolating switch and the arc extinguishing chamber are completely sealed in a gas tank filled with dry air. The gas tank is made of stainless steel and is automatically welded by the robot. The protection level of the gas tank reaches IP67. IHM-RMUA air-insulated switchgear does not use any greenhouse gases or harmful gases. It is compact, small , modular, and maintenance-free.

IHM-RMUA Air Insulated Switchgear consists of three types of switch module: Module V (circuit breaker unit), Module C (load break switch unit), and Module F (load break switch and fuse combination unit), which can be flexibly combined and expanded as per customer requirements.
