TYPE JF Partial Discharge Shielding Room (Factory Building) is suitable for the partial discharge experiment and impact test in different voltage band (110KV, 220KV, 500KV, 750KV,1000KV) of cable, voltage transformer, transformer, switch, and power station etc.
Since 1993, TYPE JF Shielding Room (Factory Building) has got the approval of the international companies such as Heafely and Hepo, which is instead of the import, and wins the f***orable comment from customers, designing institute and foreign company deeply.
Until Jun. 2004, Samgor Company has finished 31 sets of partial discharge shielding room 110KV-1000KV. Among them, there are Tai Mountain International Cable and Electric Equipment Group Co., Ltd (Shandong ), Baosheng BICC General Cable Co., Ltd (China, America and Britain joint-venture), Shengu Cable Company ( Japanese Guhe Company
control interest) 500KV, high voltage testing shielding hall of ABB Transformer (Chongqing) Co., Ltd, Transformer Research Institution (Shengyang), electric promotion door 10 x 15 (H) m of Shenyang Transformer Co., Ltd, shielding factory building of Xinhua Lida Cable Co., Ltd (Hebei), Hengyang Transformer Co., Ltd of TBEA etc.
