How long is electrical wiring changed commonly?

I am to share a Ju Meitu and the Li Gong of flying Chinese ink that decorate experience everyday, if you feel my answer is interesting and practical, that nods an assist ~

My home encounters this situation. Bridal chamber just was taken in one's hand, pa Mom comes over to decorate, but I am bought every time decorate material they are disrelished expensive. This not before paragraph time old Mom moved one pile electrical wiring suddenly, say to me the home is decorated with, can save next brushstroke money so! Decorate a master to state old electrical wiring wants to be able to be used inside the expiration period only, and the electrical wiring in domestic outfit is not to need to change.

These electrical wiring that I know to old Mom moves my home later are kin completely when be being decorated before the home, remained, say less also with respect to ten years, want to feel time is ages ago, and the problem that does not say the expiration period, smooth quality makes me very afraid. But the master says to do not have a thing however, the expiration period of electrical wiring of average home outfit is 30 years probably, actually this to a lot of families should influence of it doesn't matter, after all your home just is decorated 30 years impossibly.

Although say those who grow to the expiration period that electrical wiring finishs in normal circumstance is held out, but if you were not saved good, put it below the environment of a few moisture, accelerate the rate of electrical wiring ageing so, greatly cut the service life of electrical wiring. Be being decorated in home of a lot of owner now is dim store electrical wiring, for example electrical wiring from go inside the wall, also won't quicken the insulation ageing of electrical wiring so, the electrical wiring with have some of quality good even uses 449 years also problem of it doesn't matter, need not change so an outfit electrical wiring.

The electrical wiring in domestic outfit besides use inside the expiration period, do not need to change commonly, unless be electrical wiring appeared,ageing perhaps damages, be about to change at that time, not was necessary to change regularly below normal circumstance.

So does the home install electrical wiring to have the expiration period? It is some actually, be about to decide according to the sort of electrical wiring, use condition, use method and temperature as to the accident of time, so the electrical wiring that says my home has done not have the expiration period apparently, it is OK choose place to need electrical wiring to use from which, this can save me a large sum of silver!
