Should the aging property of wires be managed and charged?

It must be managed. I don't think there should be a charge. I paid for it when I bought a house.

For example, at present, many fires in China are caused by short circuit of wires, so it is very important to use non-combustible wires for civil use. We are a manufacturer of fluoroplastics in Li Chang, and fluoroplastics have noncombustible materials. At present, domestic fluoroplastic lines are only used for laying lines in bullet trains, military and aerospace pilot areas or some high-end office buildings, and few are used for civilian use. Foreign countries are different. Foreign fluoroplastic thread has been very popular.
