Yellow three-layer insulated wire high temperature withstand voltage UL certification
Conductor outer diameter detection
For the measurement of the outer diameter of the conductor, a measuring device with an accuracy of 1/1000mm, such as a laser outer diameter tester, shall be used. The insulation layer shall be removed in a way that does not damage the conductor properly. The conductor diameter shall be measured in the same way as the outer diameter of the finished product, and the average value shall be the outer diameter of the conductor
Insulation Thickness Detection
It is represented by 1/2 of the difference between the outer diameter of the finished product and the diameter of the conductor, but its thickness should be evenly coated on the conductor
Conductor Resistance Detection
Take a sample with a length of 1m, and use the following method to measure the resistance: use a double bridge or a potentiometer to measure the resistance at a constant temperature within the range of 5C ~ 35C, and the measurement of the resistance must not make the measurement current affect the determination The results are affected, the measured value is converted to the value of one kilometer at 20C by formula 1
