Conductor Resistance Fixtures are used to test conductor resistance. Measurement of the resistance of electrical conductor materials and other conductor materials as specified in Conductive Core Resistance Test Methods. The Wewon’s conductor resistance test device can be used in conjunction with QJ57, QJ44, QJ36, QJ19, SB2230, SB2232 and other double-arm bridges and digital resistance testers.
The fixture is equipped with a potential fixture and a current fixture, which can ensure the accuracy of measuring the current resistance of the conductor. The conductor resistance fixture can precisely measure the resistance of wires with various specifications and lengths calibrated to 1 meter. It is a necessary test supporting equipment for the wire and cable industry and engineering quality inspection centers.
Wewon’s conductor resistance fixture comply with the test standards of GB/T 3048.1 Test methods for determining electrical properties of electric cables and wires and GB/T 3048.4 Test methods for electrical properties of electric cables and wires – Parts 4 : Test of DC conduct resistance.
What is DC Resistance? DC resistance is the opposition to the flow of direct current, which can be measured and determined by applying the Ohm’s Law. It is important to keep in mind that DC resistance can vary depending on the material used, its temperature, and other environmental factors.
When measuring DC resistance of conductors, it is important to consider the various factors that can significantly affect readings. Temperature, for example, is an important factor to consider as it has a direct relationship to the resistance and can cause significant variations in measurements. Additionally, contact between the materials being tested can also have an effect on readings due to current leakage.

When performing DC resistance tests, safety should always come first. It is essential to follow all safety protocols when making connections and disconnections. If a conductor is uninsulated, use insulated handles for the probes and ensure that no current will flow through an operator’s body. Additionally, it is important to follow all instructions provided by the manufacturer in order to maximize the accuracy of the readings.
To calmly interpret the measured resistance, always take at least two separate readings to compare with each other. This will help you ensure that the results are accurate and reliable. If the results differ significantly, it may indicate that something is defective or malfunctioning. Make sure to check for cross-refrencing against any established standards for a much more precise measurement. Repeat your tests if necessary and feel free to move on if all values are within tolerance as defined by your test spec.
