With the continuous development of modern power systems, accurate voltage measurement and reliable protection equipment have become increasingly important for substations and high-voltage transmission networks. Usune has strengthened its product portfolio by providing high-performance Capacitor Voltage Transformer (CVT) solutions designed for stable operation, accurate measurement, and long-term reliability in power applications.

LB6-110kV Current Transformer is a high-voltage current transformer designed for current measurement, energy metering and relay protection in 110kV AC power systems. Suitable for 50Hz and 60Hz electrical networks, this transformer provides stable performance and high measurement accuracy for substations, power transmission systems and industrial power facilities.

SF6 gas insulated ring main unit (commonly known as gas cabinet) is a fully sealed and fully insulated medium-voltage switchgear that uses sulfur hexafluoride (SF6) gas as the insulating and arc-extinguishing medium. All live conductive components are enclosed inside a stainless steel sealed gas tank filled with low-pressure SF6 gas, providing complete isolation from external environmental conditions.

The 220kV Disconnect Switch is a high-voltage outdoor isolation device designed for 220kV AC power transmission substations. It is mainly used to isolate electrical circuits, provide a visible safety disconnect point, and ensure safe maintenance operations for high-voltage equipment.

The High Voltage Indoor Type Vacuum Circuit Breaker (VCB) uses vacuum as both the arc-extinguishing and insulating medium. Designed for 10kV–35kV power distribution systems, it provides reliable protection and control for electrical equipment in power plants, substations, industrial facilities, mining enterprises, and commercial power networks.

With the continuous upgrading of urban power grids, new energy power generation and industrial power supply systems, compact, intelligent and low-maintenance medium voltage switchgear has become an indispensable core equipment for power distribution engineering. The Ring Main Unit With Circuit Breaker, represented by XGN15 series SF6 air-insulated ring main unit, has gradually replaced traditional bulky switchgear due to its small footprint, stable performance and strong scalability. This blog takes the products manufactured by Zhejiang Usune Electric Co., Ltd. as the core, comprehensively introduces product features, complete technical parameters, internal structure, operating specifications, application scenarios and supporting services.
