 MAICHAO Discharge Tube Co., Ltd. is a professional one, which engages  in research and  development,  manufacturing and sale on advanced application technical products. It is established in 2001 and  located in Wenzhou, Zhejiang province of China.Gas discharge tube (GDT,also call gas-filled surge voltage arrester, or surge arrester, or arrester) is one of our important  products.  It's  a  special  metal ceramics structure gas discharge  electrical component made  through braze welding.  It mainly uses for  over-voltage  protection of telecom munications installations, Cable TV, coaxial cable, computer,  modem, signal line, AC line and other electrical equipment.Sw-itching spark gap is  a special gas discharge tube, it's used for igniting switch.

  Our gas discharge tubes possess advanced technology and excellent quality. They not only meet China's standards GB/T 9043, YD/T 694 and GA 173 etc.,but also satisfy international standards such as ITU-T K.12, IEC 1000.4.5, IEC 6164-1, RUS/IEEE 465.1.Meanwhile,our gas discharge tubes are excellent in quality and reasonable in price as follows:
