Descrição

Product Description
BT-900A cable semi-conductive shielding layer resistivity tester is designed according to the test methods and technical specifications specified in the national standard IEC60840. It is used to test the resistivity of high-voltage cable semi-conductive inner and outer shielding layers.Using the principle of four-terminal current-voltage step-down method, the influence of contact resistance and lead resistance generated in the test can be effectively eliminated.The resistance of the shielding layer of cables with different diameters can be measured quickly and accurately through a dedicated test stand.
The electrical box has a high-precision digital voltmeter with a measurement range of 10μV - 2V.High stability DC constant current source, the output current is continuously adjustable from 0.1μA - 10mA, the measurement resistivity range is wide from 10-10⁴
