The components should be stored in a dry place. If the insulation resistance drops below 1 megohm due to long-term storage, they can be dried in an oven at about 200°C for several hours (or passed under low voltage for several hours) to restore the insulation resistance. 2. When carbon buildup is found on the surface of the tube, it must be removed before use to avoid reduced efficiency or potential damage to the component. 3. When melting bitumen, paraffin, and other solid oils, the voltage should be lowered initially and then increased to the rated voltage after melting to prevent power concentration and extend component life.
