UL Wire & Cable
UL Wire & Cable
UL wire also named UL approved cable, refers to wires and cables that have obtained UL certification. UL is short for Underwriters Laboratories Inc. The UL Safety Laboratory is the most authoritative in the United States and the largest private organization engaged in safety testing and appraisal in the world. It is an independent, nonprofit organization that conducts experiments for public safety. It uses scientific testing methods to study and determine whether various materials, devices, products, equipment, buildings, etc. are harmful to life and property and the degree of harm; to determine, compile and issue corresponding standards and help reduce and prevent life Data on property losses. UL certification is a non-compulsory certification in the United States, mainly for product safety performance testing and certification, and its certification scope does not include product EMC (electromagnetic compatibility) characteristics.
UL is engaged in product safety certification and business safety certification business, and its ultimate goal is to obtain products with a considerable safety level for the market, and to contribute to the guarantee of personal health and property safety.

Basic test methods for UL cable
At present, UL power cable are widely used in household appliances, automobiles, computers and other fields. Since different electrical appliances are equipped with different power wire, therefore there are more and more types of them. Perhaps you've already known that the UL power cable is what, but you don't know how to test it. Here, Let us introduce the test method of UL power wire as below:1. Burning test
It corresponding to the burning grade and test method of other kind of wire.
2. Wire measurement
Measure conductor resistance, wire diameter, cross-sectional area, conductor insulation thickness etc.
3. Insulation resistance test
The test method is the same as common wire and cable, common outdoor type "w" wire and cable, etc.
4. Tensile test before and after aging
Test the tensile speed of the testing machine and the tensile index of the material.
5. Spark test
For single-core UL wire , such as CXTW, the withstand voltage test is equal to the spark test. For multi-core UL cable, you can use the spark test to take place of the withstand voltage test in daily production tests.
6. Withstand voltage test
You should apply voltage between the wires in the cable that corresponding to UL62 Table51.1. When applying voltage, you should slowly increase it from zero to the rated value within 10s to 60s, and maintain for 1 minute. The judgment criterion is that the Hi-pot machine circuit alarms during the voltage rise, fall and hold periods.
In addition to the above, you can also test it by methods of UV resistance test, oil immersion test, insulation layer tightness test, surface printing firmness test, tensile test, sheath surface insulation resistance and other tests. So everyone must test UL power cable by correct test method.
