User Needs

With large-scale urban development and the rapid rise of high-rise buildings, demand for electric power is continuously increasing. In densely loaded urban areas, the continuity and reliability of power supply have become particularly critical.

Emergence of Ring Main Units

To address severe power supply challenges, more and more users are adopting ring-main-structured distribution networks to improve reliability and ensure continuity of supply, minimizing the impact of equipment faults and maintenance outages. As a key component in ring-main operation, ring main units are being applied more widely in distribution network upgrades.

Evolution of Ring Main Units

Traditional ring main units mostly use sulfur hexafluoride (SF₆) gas as the insulation medium. While offering excellent arc-quenching properties, they carry the risk of gas leakage, posing significant hazards to both the environment and on-site personnel. This has led to the emergence of solid-insulated ring main units.
