概述   Outline

GT-12 系列固體絕緣環網柜，是一種全絕緣、全密封、免維護的固體絕緣真空開關設備。高壓帶電部分均用絕緣性能優良的環氧樹脂材料澆注成型，將真空滅弧室、主導電回路、絕緣支撐等有機結合為一整體，功能單元通過全絕緣固體匯流母線連接。因此，整個開關設備不受外部環境影響，可保障設備運行的可靠性和操作人員的安全性。 

該環網柜具有結構簡單、操作靈活、聯鎖可靠、安裝方便等特點，適用于 50Hz，12 干伏的電力系統，廣泛應用于工業及民用電纜環網及配網終端工程，作為電能的接受和分配之用，特別適用于城市居民區配電、小型變電站、開閉所、電纜分支箱、箱式變電站、工礦企業、商場、機場、地鐵、風力發電、體育場、鐵路、隧道等場所使用。 

由于該產品具有全絕緣、全密封、全屏蔽的優點，所以特別適用于高海拔、高溫、濕熱、嚴寒、污染嚴重等環境惡劣的地區使用。 

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.
