How to use rubber soft plug in high and low temperature test chamber

The test samples in the high and low temperature test box are divided into live test and uncharged test.The live test sample needs to open a test lead hole on the right side of the test box for the test cable to pass through the lead hole and block the lead from outside to inside If the hole is not blocked,the outside air will penetrate into the test area,which will affect the temperature or humidity control.Make a notch in the plug,the size is the same as the sample cable,install the cable in the notch.When the lead hole is not used,install the rubber soft plug inside and cover the outside,so as to ensure the temperature inside the box.
The function of the lead test hole can be connected to the test power line or signal line(diameter 50mm,one standard,if the aperture and the number of holes need to be increased,please specify when ordering)

Warm reminder:The external cable needs high temperature test and low temperature test to prevent the cable from being unable to withstand the high temperature and low temperature and causing electrical leakage,which may cause hidden safety hazards.
