①Polyvinyl chloride (PVC) material wire and rubber wire: Assembled in the temperature test power line branch of electrical products does not exceed 50K (75 ℃);
Power cord swing test: (fixed plug swing power cord)
The first type: For a conductor that will bend during normal work, add a 2kg load to the power cord and 90 ° vertical (two 45 ° each) swing 20,000 times. The power cord body and plug must not be abnormal and must be conductive (frequency 60 times per minute);
Second type: For the wires that are bent during user maintenance (wires that do not bend during normal work), add a 2kg load to the power line at 180 ° and test 200 times without abnormality (frequency 6 times per minute)
