Power Frequency EDM

The SPARK TESTER is designed and manufactured in accordance with Standard GB/T3048.9-94 and Standard JB/T4278.10-93 on the basis of learning from similar products at home and abroad, and is suitable for the power frequency spark test on the insulation layer of rubber and plastic wires and cables. In addition, it is known as an important test equipment to ensure the insulation quality of wires and cables.

I. Usage

The 25KV type power frequency SPARK TESTER meets the test requirements of the new national standard GB/T3048-2007, and is a professional equipment to detect wire, cable, insulation and sheath defects.

It adopts the solid state AC voltage regulation and single-chip microprocessor control technology, characterized by stable output of high voltage (subject to no grid voltage change), high detection sensitivity, good field adaptability, convenient to use, safety and reliability and novel and beautiful structure.

The tester is dedicated for the dielectic strength test on finished cables of insulation wires whose test voltage value is 25KV and below.
