概述   Outline

GT-12 系列固体绝缘环网柜，是一种全绝缘、全密封、免维护的固体绝缘真空开关设备。高压带电部分均用绝缘性能优良的环氧树脂材料浇注成型，将真空灭弧室、主导电回路、绝缘支撑等有机结合为一整体，功能单元通过全绝缘固体汇流母线连接。因此，整个开关设备不受外部环境影响，可保障设备运行的可靠性和操作人员的安全性。 

该环网柜具有结构简单、操作灵活、联锁可靠、安装方便等特点，适用于 50Hz，12 干伏的电力系统，广泛应用于工业及民用电缆环网及配网终端工程，作为电能的接受和分配之用，特别适用于城市居民区配电、小型变电站、开闭所、电缆分支箱、箱式变电站、工矿企业、商场、机场、地铁、风力发电、体育场、铁路、隧道等场所使用。 

由于该产品具有全绝缘、全密封、全屏蔽的优点，所以特别适用于高海拔、高温、湿热、严寒、污染严重等环境恶劣的地区使用。 

GT-12series solid insulated ring network cabinet is a fully insulated, fully sealed and maintenance-free solid insulated vacuum switchgear. All high voltage live parts have excellent insulation properties The epoxy resin material is poured and molded, and the vacuum interrupter, the main conductive loop, the insulating support and the like are organically combined as a whole, and the functional units are connected by a fully insulated solid bus. therefore, The entire switchgear is not affected by the external environment, ensuring the reliability of the equipment and the safety of the operator. 

The ring network cabinet has the characteristics of simple structure, flexible operation, reliable interlock, and convenient installation. It is suitable for 50Hz, 12 dry volt power systems and is widely used in industrial and civil cables.The ring network and distribution network terminal project is used for the acceptance and distribution of electrical energy, and is particularly suitable for distribution in urban residential areas, small substations, opening and closing stations, cable branch boxes, box-type substations, and workers.Mining companies, shopping malls, airports, subways, wind power, hospitals, stadiums, railways, tunnels and other places. 

Because this product has the advantages of full insulation, full sealing, and full shielding, it is particularly suitable for use in areas with high altitude, high temperature, hot and humid, severe cold, and severe environmental pollution.
