Today let me introduce the inspection of power cord for you.
For the power cord, Lediant checked it more than 3 times.
First of all, when the material enters our factory, we will do a hand inspection.
Secondly, daily inspection is performed during the production process.
Finally, after the downlights are finished, we will also carry out corresponding sampling inspection.
Generally speaking, different downlights, according to the requirements of different customers, we will carry out different times of cord anchorage test. The cord anchorage test is to check the retentivity of the power cord.
Lediant's standard: The power flexible wire must be equipped with a pressing device to prevent the flexible wire from being pulled out. Pull 25 times,the displacement of it will not exceed 2mm.
