​In today's rapidly developing power distribution industry, the role of the Cable Branch Cabinet has become increasingly important. As urban construction and industrial projects demand safer and more efficient electricity management, this equipment ensures reliability and stability. A Cable Branch Cabinet is not only a distribution point but also a protective system for underground cables, making it indispensable in power networks.

Ring Main Unit (RMU) is a type of compact, sealed, and fully insulated switchgear that is a cornerstone of the secondary distribution network. It is designed to provide reliable and safe distribution of electricity in urban and industrial areas. RMUs are widely used in medium voltage networks and play a pivotal role in ensuring the continuity of power supply. This article aims to provide a comprehensive overview of RMUs, including their definition, working principle, product features, details, advantages, classification, detailed technical parameters, application scope, and more.

High-voltage switchgear plays a critical role in electrical power systems, and the degradation of switchgear operation is one of the causes of system faults. This article explores the types, common faults, and analysis of high-voltage switchgear. It covers indoor and outdoor configurations, fixed and detachable types, and highlights the development of central switchgear in recent years. The main focus is on analyzing faults related to insulation, conduction, and mechanics, including sticking and misoperation, switch malfunctions, insulation failures, overload faults, and external factors. Understanding these common faults is crucial for ensuring the safe operation and maintenance of high-voltage switchgear..

Our company is pleased to announce our latest project, the supply of high-voltage switchgear equipment to the Huaineng Jiangsu Rudong H3 offshore wind power plant. Our commitment to quality, innovation, and customer satisfaction is evident in our successful bid for this project.

Prefabricated substations, also known as prefabricated electrical substations or packaged substations, are self-contained units that integrate various electrical components, such as transformers, switchgear, protection devices, and control systems, into a single enclosure. These substations are designed to be compact, modular, and easily transportable, offering a convenient solution for power distribution needs in diverse settings. For instance, in the construction industry, prefabricated substations are often used to power temporary facilities on job sites.

​The S11 35KV Oil-immersed Power Transformer is a state-of-the-art electrical device designed for efficient power transmission and distribution in medium- to high-voltage networks. Known for its low loss, quiet operation, and exceptional durability, this transformer has become a preferred choice for power utilities, substations, and industrial applications.
