Product Details

I. Product Overview

  According to the requirements of the new preventive test procedures for power equipment, the conductive circuit resistance test of various switchgear is a mandatory item, with a test current of not less than 100A and a continuous current time of not less than one minute. To this end, our company has designed and developed a new generation of loop resistance tester series products, which are suitable for testing the main contact resistance of high and low voltage switches, and the DC resistance of high and low voltage cable lines.JYL (100A) Loop Resistance Testeradopts 100A/50A constant current output, and can use test leads with finer cross-sections, reducing the labor intensity of field testers. The test data is displayed on a backlit dot-matrix LCD, suitable for different working environments.
