The CMM-260C is a mining power transformers online drying system that has been designed by GlobeCore for use in harsh environments, such as in the mining industry. Its key benefit is the capacity to extract moisture from transformer oil and insulation without compromising equipment functionality. In the mining industry, transformers are subjected to high loads and operate in environments characterised by dust, moisture and temperature fluctuations. Consequently, moisture accumulates in the oil, which reduces its insulating properties and can lead to accidents. Previously, the transformer had to be shut down to rectify the issue. However, the CMM-260C now enables us to resolve the problem without having to shut down the transformer. The unit is connected to a functional transformer and initiates the oil-drying process. The oil is cleaned, the moisture is removed, and the purified oil is then reintroduced into the system. All processes are automated, with no need for human intervention, and the system independently controls temperature, pressure and humidity. GlobeCore is a reliable solution for those who value safety, efficiency and continuity of production processes.
