1.主母線最大(da)額定電(dian)(dian)(dian)(dian)(dian)流(liu):主母線最大(da)能夠(gou)承(cheng)(cheng)載的(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)的(de)(de)額定值(zhi)。2.額定短(duan)時(shi)(shi)耐受電(dian)(dian)(dian)(dian)(dian)流(liu):由生(sheng)(sheng)產(chan)廠家給出的(de)(de),成(cheng)套設備中(zhong)某條(tiao)(tiao)電(dian)(dian)(dian)(dian)(dian)路(lu)在(zai)國家標(biao)準GB7251.1-2005中(zhong)8.2.3規(gui)定的(de)(de)試驗條(tiao)(tiao)件(jian)下能安全承(cheng)(cheng)載的(de)(de)短(duan)時(shi)(shi)耐受電(dian)(dian)(dian)(dian)(dian)流(liu)方(fang)(fang)均根(gen)值(zhi)。3.峰(feng)值(zhi)短(duan)時(shi)(shi)耐受電(dian)(dian)(dian)(dian)(dian)流(liu):在(zai)規(gui)定試驗條(tiao)(tiao)件(jian)下,生(sheng)(sheng)產(chan)廠家規(gui)定此電(dian)(dian)(dian)(dian)(dian)路(lu)能夠(gou)圓滿地承(cheng)(cheng)受的(de)(de)峰(feng)值(zhi)電(dian)(dian)(dian)(dian)(dian)流(liu)。4.外殼(ke)防(fang)護等級:IEC60529-1989標(biao)準由成(cheng)套設備提供的(de)(de)防(fang)止觸及帶電(dian)(dian)(dian)(dian)(dian)部(bu)件(jian),以及外來(lai)固體的(de)(de)侵入和液體的(de)(de)進入的(de)(de)等級。具體等級劃分詳見IEC60529標(biao)準。5.內(nei)部(bu)分隔方(fang)(fang)式:根(gen)據(ju)IEC60529-1989標(biao)準,為保(bao)護人身安全,將開關柜(ju)(ju)獨立劃分成(cheng)幾(ji)個隔室的(de)(de)不(bu)同方(fang)(fang)式。不(bu)同型(xing)號(hao)的(de)(de)配電(dian)(dian)(dian)(dian)(dian)柜(ju)(ju)之(zhi)間的(de)(de)技術(shu)參(can)數都有很大(da)不(bu)同,而(er)進口配電(dian)(dian)(dian)(dian)(dian)柜(ju)(ju)的(de)(de)技術(shu)參(can)數基本都優于(yu)國產(chan)配電(dian)(dian)(dian)(dian)(dian)柜(ju)(ju),但并不(bu)能認為進口配電(dian)(dian)(dian)(dian)(dian)柜(ju)(ju)就(jiu)一定比國產(chan)配電(dian)(dian)(dian)(dian)(dian)柜(ju)(ju)好。

在非金(jin)屬(shu)材(cai)料中，纖維(wei)增強聚酯材(cai)料有著優秀的抗(kang)(kang)老化(hua)性(xing)能(neng)(neng)。經過抗(kang)(kang)老化(hua)性(xing)能(neng)(neng)測試表明(ming)，使用地點不同，所處氣候帶(dai)不同，其(qi)表面(mian)最大(da)老化(hua)厚度為(wei)20年小于50μm。大(da)多數箱體的最小厚度為(wei)5mm，小于箱體厚度的1%，因此對箱體的機(ji)械性(xing)能(neng)(neng)沒有明(ming)顯的影響。令(ling)外該公司(si)采取(qu)了一種特殊的耐(nai)紫外線表面(mian)處理工藝，更(geng)加強化(hua)了其(qi)耐(nai)老化(hua)性(xing)能(neng)(neng)。

由于電動汽車每天需要補充大量電能，交流充電樁經營充電站就可以獲得巨大的充電服務收益。相對于加油站，電能比較安全和方便，可在各地大量安裝設置充電站。根據投資規模，小到社區慢速充電樁，大到公路快速充電站，單站經營，組網經營均可。對于充電站市場的開放，專業交流充電樁國家電(dian)網以(yi)后可(ke)能更多地會偏向服(fu)務和電(dian)力供(gong)應，讓充(chong)電(dian)站(zhan)建設更充(chong)分地與市(shi)場融合，大(da)家都將是同一(yi)個市(shi)場的(de)競爭者。因此提前準備、提前規劃(hua)，對從事電(dian)池生產的(de)企業來說很重(zhong)要。充(chong)換電(dian)市(shi)場，政策有(you)傾斜(xie)，市(shi)場有(you)潛力，投資又少，將面臨(lin)較大(da)的(de)商機。
