Preventive testing is conducted to identify potential hazards of equipment in operation, prevent accidents or equipment damage, and to inspect, test, or monitor equipment. It also includes testing with oil or gas samples to assist factories in better protecting electrical equipment, ensuring safer and smoother electricity use, avoiding power failures, and avoiding losses. However, there are many testing and prevention methods in preventive testing, insulation test for power cables is one of them;
Insulation resistance testing is one of the numerous quality assurance tests and processes used by our cable experts to check the compliance of our power cables. Our advanced facilities also conduct independent testing for power cables from third parties to ensure that unqualified cables do not enter our broader supply chain.
Insulation resistance testing is a key test for cables, as it can measure the insulation effect of the cable. Poor insulation may cause short circuits, electric shocks, or fires.
Characteristics of cable and wire insulation testing:
1. Suitable for insulation testing in the maintenance, testing, and calibration of various electrical equipment.
2. 31/2 LCD large screen digital display, high resolution, and convenient reading.
3. There are four rated insulation test voltages with strong load capacity.
4. Easy to operate, easy to carry, accurate, reliable, and stable.
5. Low power consumption, 12V/1.8AH lithium battery power supply, long service life. (Alternatively, AC 220V power supply can be used.)
6. The battery voltage is insufficient and there is an undervoltage indicator displayed.
7. Equipped with shockproof, dustproof, and moisture-proof structures, suitable for harsh working environments.
8. The protection function is complete and can withstand short circuits and residual voltage surges of the tested electrical equipment.
The steps for testing insulation resistance are as follows:
Connect the electrode interfaces of the testing instrument to the metal conductors at both ends of the wire and cable to be tested.
Set the parameters of the testing instrument, including measurement range, current, etc., and turn on the power.
After the test command appears, start recording the resistance value.
After recording the test, turn off the power and disconnect the test instrument from the wires and cables to be tested.
