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..

Air Insulated Switchgear (AIS) is a crucial component of high voltage switchgear that utilizes air as the insulation medium for the busbars and circuit breakers.

Ring main units are storage cabinets commonly found in large residential complexes, malls, and power companies. Their primary function is to connect ring main lines and enhance their power supply reliability through functions such as ring main line merging or load shedding. In simple terms, when a line experiences a fault or requires maintenance, the remaining lines within the ring main unit can be utilized for transmission, ensuring stable and reliable operation of the distribution system. This article will discuss the advantages of ring main units in detail.

​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.

the 35kV gas insulated switchgear (GIS) is not just a compact, safe, and reliable solution for high voltage power distribution and transmission applications. It is a crucial component that ensures the efficient and secure supply of electrical power to various industries and communities. Its use of SF6 gas as an insulating and arc-quenching medium, along with its modular design and enhanced safety features, make it an ideal choice for modern electrical power systems. With its ability to operate at voltage levels of up to 35kV, GIS plays a pivotal role in the energy industry, safeguarding the uninterrupted power supply to industries and communities.
