The main water delivery channel of the Zhengzhou section of the South-to-North Water Diversion Project starts from the starting point A of the Yellow Crossing Project in the south to the exit of the Chuanzhang Project. The project safety monitoring within a total length of more than 256 km adopts the data acquisition equipment (MCU), cabinets, Solar power supply system, lightning protection grounding, optical transceiver, wireless communication equipment and other supporting facilities. Our Kweight battery participates in the installation, commissioning.

Kangbao Ranch Wind Farm is located in Kangbao County, Zhangjiakou City, Hebei Province, with an installed capacity of 100MW, a total investment of 750 million yuan, and an annual power generation of about 270 million kWh.

This project is mainly for the replacement of the DC power supply system of the booster station of the Kangbao Ranch wind farm. The GZDW220/800A high-frequency switching power supply charging cabinet, DC link cabinet, DC feeder cabinet, DC distribution cabinet, and KL KL series long Life KL2-800 battery.

Provided an integrated power system (DC220, 400A) and supporting lead-acid batteries (2V500AH) for the State Grid Shandong Electric Power Company. The project was accepted in 2019 and was used well on site.

The 25kW photovoltaic power stationin Ruoqiang County, Bazhou, Xinjiang, is located in the Altun Mountain National Nature Reserve with an altitude of 4475 meters. It is a challenging plateau photovoltaic power station. The temperature diference between day and night reaches 40-50 degres. It uses Kweigh KG2V1000AH solar gel battery. The excellent characteristics of temperature diference can stil output electricity stably even when the temperature is extremely low at night, which solves the problem of dificut electricity consumption for herders. The photovoltaic clean energy also provides a blue sky for wildlife in the reserve.

This project is located by the Poyang Lake in Jiujiang City, Jiangxi Province. The lake area has high humidity. The renovation project is mainly to remove 55 sets of UPS devices of the original gold fan unit 1500kW wind turbine converter system and replace them with "Kweight" production KL 3kVA 55 KL3kVA UPS, replace the backup battery, each 1500kW wind turbine uses 16 "Kweight" KW small series KW12-12 batteries, after replacement, you need to ensure that the wind turbine converter system continues to operate for 15 minutes after power failure. The project will be completed in May 2020, and the equipment is operating normally and reaches the design standard.
