　　感應式(shi)電能(neng)表對(dui)工藝要(yao)(yao)求高，材料涉及廣泛，有(you)(you)(you)金屬、塑料、寶石、玻(bo)璃、稀土等等，對(dui)此(ci)，產品的相關材料標準(zhun)都有(you)(you)(you)明確的規(gui)定和要(yao)(yao)求，用低價的劣(lie)質(zhi)(zhi)材料代替標準(zhun)規(gui)格的材料是影響(xiang)電能(neng)表產品質(zhi)(zhi)量(liang)的主要(yao)(yao)問題(ti)之(zhi)一，因此(ci)像大多數(shu)商品一樣(yang)，價格過低的商品不會有(you)(you)(you)好(hao)的質(zhi)(zhi)量(liang)保證。

　　感應式電能表(biao)的(de)生(sheng)(sheng)產(chan)(chan)工(gong)(gong)藝(yi)復雜，但早已成(cheng)熟和(he)穩(wen)定(ding)，工(gong)(gong)裝器(qi)具也(ye)全(quan)面配(pei)套。生(sheng)(sheng)產(chan)(chan)環境(jing)對溫度(du)(du)、濕度(du)(du)和(he)空氣凈化度(du)(du)的(de)要求較(jiao)高。近十(shi)余年來(lai)在杭州、寧波、溫州等(deng)地發展形成(cheng)的(de)電能表(biao)的(de)材料和(he)零部(bu)件市場(chang)具有相(xiang)當的(de)規模，形成(cheng)鮮明的(de)中(zhong)國集約化大生(sheng)(sheng)產(chan)(chan)的(de)特色，這也(ye)是那里生(sheng)(sheng)產(chan)(chan)的(de)電能表(biao)在市場(chang)上具有價格優勢(shi)的(de)主要因素之(zhi)一。
