Pd Testing System For Xlpe Cable

These PDST series PD Testing System for XLPE Cable suits the test of PD detect, withstand test and PD fault locate of the XLPE cables under 110kV. The relevant recommendations; GB/T11017-2002,GB/T1276-2002 and IEC60502-2005. PD testing system has the advantage of the compact structure, multi-function, easy operate and satery. It can supersede the analogously equipment of foreign production. It is composed of high voltage reactor, double shield isolation transformer, regulator, high voltage capacitive divider, high voltage injection capacitor, PD detector, PD fault locater and shielded room.
2.Main feature
