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.

The IHM-RMUG Solid Insulated Switchgear uses environmentally friendly and pollution-free epoxy as insulating medium. The switch and the high voltage live parts are epoxy resin cast, and the earth and phase-to-phase connection adopts epoxy resin as insulation medium as well. This switchgear is free from gas leakage, explosion. It has good insulation performance and doesn’t need maintenance.

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-6500-FLW34 series SF6 Load Break Switch use on distribution lines for all voltage classes rated up to 40.5kV(12kV, 24kV,40.5kV) at 50/60Hz power system. It uses for opening or closing the load currrent and closing short circuit current.

IHM-6500-FLW34 adopts SF6 arc extinguishing, SF6 insulation. It can be open or close by manual or electric.

IHM-6500-ZW32 series vacuum circuit breakers use on distribution lines for all voltage classes rated up to 38kV(15kV, 27kV, 38kV) at 50/60Hz power system. It uses for opening and closing the load current, overload current and short circuit current.

IHM-6500-ZW32 uses spring operating mechanism, it can be open or close by manual or electric. It can be pole mounted or ground mounted and suitable for overhead line and substation.

IHM-6500-ZW32 has the characteristics of small size, light weight, anti-condensation and maintenance-free, which can be used in harsh environment.

The iCB3 series residual current protection circuit breakers (intelligent re-closing) are suitable for three-phase four-wire neutral point directly earthed (TT) 50Hz/60Hz AC distribution networks with a rated voltage of 400V, a rated insulation voltage of 1000V and a rated current of up to 800A. It is designed to provide protection against indirect contact and to prevent fire hazards caused by earthing fault currents due to equipment insulation damage. It can also be used to distribute power and protect lines and power supply equipment from overload, under-voltage, short-circuits, single-phase earthing and other fault hazards. The iCB3 series intelligent circuit breakers are multifunctional, integrated device with communication capabilities and adjustable load current residual current action circuit breakers with automatic re-closing function. It complies with all intelligent requirements of smart grid management, making it particularly suitable for comprehensive protection at various levels of urban and rural power networks. It is the preferred product for supporting the operation of the national smart grid.
