20 2025-06 Why Has the Dry Type Transformer Become the Ideal Choice for Modern Urban Power Distribution Systems?
A dry type transformer is a power transformer that does not use liquid insulating media, relying instead on air convection for cooling. It offers advantages such as safety, environmental friendliness, and easy maintenance. Widely used in urban power grids, high-rise buildings, airports, hospitals, and subways—places with high fire safety requirements—dry type transformers are increasingly favored due to their excellent performance and eco-friendly design as the power industry modernizes.
13 2025-06 What Is an Electrical Substation and How Important Is It in a Power System?
An Electrical Substation is a key node in the power system, mainly responsible for voltage transformation, power distribution, and control. It serves as a central hub for delivering electricity from the generation side to end users. Through equipment like transformers, switchgear, and protection devices, the substation converts high-voltage electricity into levels suitable for transmission or usage, ensuring the safety, stability, and efficiency of the power grid. It is widely used in urban power distribution, industrial zones, infrastructure projects, and renewable energy systems—making it an essential facility for modern electricity supply.
13 2025-06 What Is an Oil Immersed Transformer and What Is Its Function?
An Oil Immersed Transformer is a type of power transformer that uses insulating oil for both cooling and insulation. It is widely used in power systems to step up or step down voltage. The windings and core of the transformer are fully submerged in special transformer oil, which ensures safety and stability during long-term operation thanks to its excellent insulating and heat dissipation properties. Oil immersed transformers are commonly applied in power transmission projects, industrial and mining enterprises, commercial buildings, and rural power grid upgrades. They are indispensable core equipment in power transmission.
09 2025-06 What Does an RMU Do in a Transformer System?
A Ring Main Unit (RMU) is a critical piece of switchgear equipment used in medium-voltage power distribution networks. In transformer applications, RMUs serve as the first line of defense by providing essential functions such as fault isolation, load management, and protection for transformers.
