What are the wire-feeding factory wire feed tests?

  As people's quality requirements for life are getting higher and higher, electric wires are an indispensable supporting facility in people's lives, and the safe use of electric wires has received more and more attention. Although the ISO9000 safety certification system is certified, most of the products in the entire wire and cable market are unqualified. These unqualified products have not been properly handled, and they are flooding the entire wire and cable market, which seriously affects the benign development of the market for UL's inferior products. In order to ensure that customers' products comply with UL certification and safety certification, wire harness processing plants mainly check the current, resistance, electrical conductivity, voltage status and appearance of wires.

According to the physical properties and mechanical properties of the wire, it is mainly checked from the aspects of voltage, conductivity, size and appearance, as follows:
  1. Detection of wire and cable size and appearance:
  1 The UL number is generally marked on the wire. The wire harness processing factory must check whether the wire supplier's UL certificate is within the validity period when importing the supplier.
  2UL certification report is true and effective.

  3 Is the appearance stained, and the actual size of the wire matches the size of the wire specification.


2. Withstand voltage test in wire and cable:

  Withstand voltage test, AC 300V, mainly for product performance test, finished wire withstand voltage test: KV/min 5000V finished product withstand voltage test for AC voltage test, also called power frequency withstand voltage test, AC withstand voltage test is for wire and cable   finished insulation Apply a certain value higher than the working voltage (rated voltage) for a certain period of time without insulation breakdown. Each product must be tested for withstand voltage before leaving the factory, and the wire harness processing plant must provide a test report for the wire supplier.


3. Aging test on wire and cable:

  When storing, it is forbidden to contact with acidic, alkaline and corrosive substances, and isolated and stored separately. The insulated wire and cable are stored in a dry and ventilated warehouse. The relative humidity should not exceed 75%, avoid direct sunlight and premature aging of the insulation.


4, under high temperature impact of 140 degrees, the temperature should not be cracked at -30 degrees.

  Wires, terminals and connectors are the main inspection materials for wire harness processing plants. In order to ensure the quality of customers' products, wire harness processing plants must test every test data of wires.
