</p><p style="text-indent:25px">進(jìn)口配電柜所采用的主要電器元件均為進(jìn)口品牌產(chǎn)品,有的柜體或一些柜體輔件必須國外進(jìn)口,這樣造成進(jìn)口配電柜的價(jià)格一般都比國產(chǎn)配電柜高出很多。　　3.進(jìn)口配電柜的技術(shù)參數(shù)雖然很高,但大多數(shù)情況只運(yùn)用了一部分,甚至于根本沒法運(yùn)用。例如進(jìn)口配電柜一臺(tái)柜能安裝的回路數(shù)比國產(chǎn)配電柜的都多,但那是在降低了回路容量的前提下才能達(dá)到,在大多數(shù)情況下是滿足不了用戶需要。　　4.國產(chǎn)配電柜的技術(shù)參數(shù)雖然比進(jìn)口配電柜的低,但在國內(nèi)大多數(shù)供配電系統(tǒng)中已經(jīng)能夠滿足用戶需要。　　5.在配電柜的質(zhì)量上,只要廠家嚴(yán)格按照3C的要求進(jìn)行生產(chǎn)﹑檢驗(yàn),國內(nèi)的配電柜的質(zhì)量并不一定比進(jìn)口配電柜的質(zhì)量差。
