DQ-630 Conductor Resistance FixtureDetailed introduction:

DQ-630 Conductor Resistance FixtureApplicable to various power cables and electrical installations specified in GB/T3048 "Test Methods for Electrical Properties of Wires and Cables"The DC resistance measurement of backup wires and cables can also be used for the DC resistance measurement of other conductor materials,This device adopts an aluminum alloy base plate, with a reasonable structure and convenient use.It utilizes a reverse screw to quickly clamp and retract the structure, making it more convenient and flexible to use. The voltage and current fixtures are separated to improve the contact point with the sample.This device adopts an aluminum alloy base plate, with a reasonable structure and convenient use.

Technical parameters:

1. Dimensions: 1530 × 210 × 150mm

2. Adaptive bridge: any bridge or digital resistance measuring instrument using the four point measurement method.

3. Scope of sample application: 1mm2~630mm2 single or multiple stranded conductor core.

4. Distance between two voltage clamps: 100~1000mm

5. Dimensions: 1530 × 210 × 150mm

6. Adaptive bridge: any bridge or digital resistance measuring instrument using the four point measurement method.

usage method:

1. Wiring: Connect the wires between the corresponding current and voltage terminals.

2. Adjustment distance: Due to the use of adjustable fixtures, it is necessary to check whether the distance between the two voltage clamps is 1 meter before measurement; The fixture must be regularly checked for a length of 1 meter with the local metrology department.

3. Adjust the distance between adjacent current fixtures and voltage fixtures to be no less than 1.5 times the circumference of the tested sample section
