    子管及半體器件用規范
  2. The high voltage windings is made by sectional aluminium foil with glass fiber and resin casting, the voltage between turns is very low, the partial discharge is very low, there is no cracking, since the expansion factor of conductor and insulation material is similar, it also has the advantages of no corrosion, no pollution, low losses, low noise level, anti - vibration, fire protection, maintenance free, long operating life and high reliability

    低壓繞組為箔繞制,半干nomex紙做層間和外層絕緣,經乾燥與箔固化為一體,散熱好強度壓繞組為分段鋁箔繞制,玻璃絲網架環樹脂澆注,層間壓低,局部放小,體和絕緣體膨脹系數相似,不裂壽命長腐蝕污染損耗小噪音低抗震阻燃免維護運行安全可靠。
  3. It has weak - link free grain boundaries and is a kind of low cost material, . which could be used under 20k ~ 30k. however, mgb2 reveals a poor jc property in high magnetic field. currently in the research of the mgb2 wires and tapes many efforts have been made to improve its grain connection or enhance the jc dependence on the magnetic field using the method of chemical doping

    二硼化鎂是迄今為止所發現的超臨界轉變溫度最的非化物超材料,它具有弱連接、成本低廉、能夠在20k 30k應用等優勢,但是mgb2在外場下的臨界流特性較差,目前在優化粉末套管法制備mgb2線帶材工藝的研究中,通過改善晶間連接和利用化學摻雜提樣品的超臨界流密度是mgb2成材研究的一個重要方向。
