Paglakip:
Ang pagkamalikhain nga nagbutang og dako nga higayon gipasabot pinaagi sa teknolohiya. Ang pagkombinar sa kasinatian sa pagbuhat sa produkto sa air-insulated switchgear ug gas-insulated switchgear, ang QGG Series Solid Insulated Switchgear gisugyot, nga nagpakita og dako nga higayon sa field sa medium-voltage teknolohiya ug may dugay nga operasyonal nga seguridad. Isip usa ka core unit sa power distribution network, gi-aplikar kini sa power distribution networks. Gi-usab kini og vacuum interrupter para sa arc extinction, ug ang iyang high-voltage live parts gihimo gikan sa solid insulating materials (epoxy resin materials) nga may maayo nga insulating performance, wala na ang air chamber nga may presyon sa 0.03Mpa, ug girealize ang full insulation, full sealing, ug walay maintenance nga operasyon. Ang QGG Series Solid Insulated Switchgear gisugdan usab og intelligent online monitoring system, nga monitor sa real-time ang status sa key components sa interior sa switchgear, magkuha sa mga estado parameters, automatikong evaluasihon ang posibilidad sa pagkaputli, ug maghatag og matibay nga proteksyon alang sa normal nga operasyon sa switchgear ug sa buong power distribution line. Human sa tuig-tuig nga dedikadong R&D, ang solid insulated switchgear miangkon sa IV product series, bawgon may iyang kaunlaran nga katangian.
