How to maintain the silicone rubber cable?

I. Silicone rubber cable maintenance method? Silicone rubber cable, also known as high-temperature precious metal RTD, is suitable for high-temperature places in various production processes, such as powder metallurgy industry, calcined bright furnace, smelting furnace and other temperature measurement, the cable is very much in use. Maintenance should pay attention to pickling passivation, the use of acid air oxidation capacity, remove high temperature precious metal platinum rhodium thermocouple surface substances and other residues that can be dissolved by acid. Of course here is also mainly high temperature precious metal platinum rhodium thermocouple made into a diameter of about 80mm round into the measuring cup, and then guided into 30% -50% (according to the volume ratio) chemically pure dilute sulfuric acid (or dilute nitric acid) for one hour. Remove into a flask, boil with pure water several times, so that the acid is completely removed. The function of pickling passivation is to clear part of the surface layer of the electrode and metal oxides. Maintenance also requires checking the surface for breakage or cracks. If there are it is recommended to return them directly to the factory. Try to avoid storing the silicone rubber cables in the open air or damp places. Then install the silicone rubber cable reel and do not lay it flat. Of course, silicone rubber cable should also be prohibited with acid, alkali and corrosive gases and substances, wire warehouse storage shall not contain harmful gases that destroy insulation and corrode metals. Silicone rubber cables need to be maintained in isolation from the ground, and choose to place wooden blocks under the wire to prevent moisture on the ground. Pay attention to whether the wire is intact. Of course, the outer sheath of the silicone rubber cable should also be checked regularly for damage, wear and tear, overloading, overheating, and so on. Run the load within the rated load flow of household electrical wiring, short circuit circuit when seriously overloaded. Check the bending radius of the cable laying, working temperature, etc. If these things are done, then the silicone rubber cable will naturally not have a problem. Of course, even better cables, we should pay attention to the maintenance work in our daily life. In short, understanding the correct maintenance methods can reduce the aging of the power cord insulation. If long-term use will inevitably lead to the aging of the insulation. But effective protection methods can not only prevent the waste of current, but also prolong the insulation aging period.
