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-6000 series transformer monitoring and protection terminal (TMPT) is an transformer monitoring terminal with measurement and protection functions based on advanced sensing technology. TMPT remote monitors transformers and HV/LV equipment through modern communication network (4G/3G/GPRS/LoRa/Bluetooth), together with functions such as relay protection, power quality analysis, abnormal event alarm, power failure management, cable temperature measurement, resume from break-point. TMPT can also be used as a data concentrator to collect power billing data of transformer operation. It provides the necessary data for early warning of equipment failure and appropriate network planning, monitoring circuits, equipment, and environments involved in transformers, timely locating faults, minimizing the impact of accidents or eliminating accidents in the embryonic stage, and thus achieving the purposes of protecting the transformer body, as well as safe, reliable and efficient operation of power distribution system.

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. 

Communication: RS485 Modbus.

Based on Internet of Things technology, APMS provides continuous and reliable power supply through functions such as equipment operation monitoring, load analysis, energy management, accident alarm, accident recording and analysis, fault recording, power quality monitoring, and remote switching control. APMS provides guarantees to realize safe, reliable and efficient operation of substations.

APMS is based on the architecture of "three-layer distribution, two networks, and integrated in one". That is to say, the devices in three different layers of equipment layer, communication layer and master station layer are connected through two networks of field bus and Ethernet to form an organic whole.
