This equipment is composed of the device generating high frequency and electrode unit In electrode, high frequency high voltage generates corona discharge in contact with jacketed copper wire. So the surface of jacket (PE, PVC, TEFLON, HDPE, LDPE) is activated and the adhesion is strengthened in the second progress, stamping.Compact size.Easy to adjust the electrode.High efficiency and with performance by using MOFSET.The interlocking device maintains the safety in operation
