JG電機(jī)引接線低壓電器是一種能根據(jù)外界的信號(hào)和要求，手動(dòng)或自動(dòng)地接通、斷開電路，以實(shí)現(xiàn)對(duì)電路或非電對(duì)象的切換、控制、保護(hù)、檢測(cè)、變換和調(diào)節(jié)的元件或設(shè)備。低壓電器的發(fā)展，取決于國(guó)民經(jīng)濟(jì)的發(fā)展和現(xiàn)代工業(yè)自動(dòng)化發(fā)展的需要，以及新技術(shù)、新工藝、新材料研究與應(yīng)用，目前國(guó)內(nèi)的低壓電器產(chǎn)品正朝著高性能、高性、小型化、數(shù)模化、模塊化、組合化和零部件通用化的方向發(fā)展。In fact, China's low-voltage electrical industry from simple imitation to manufacturing assembly, designed and developed the development of nearly one thousand series, the production of about two thousand companies, mainly concentrated in the coastal JG電機(jī)引接線areas of Guangdong, Zhejiang and Shanghai provinces, the annual output value of about twenty billion yuan. But the domestic low-voltage electrical appliances production enterprise scale is too small, the quantity is too much, more than ninety percent of the enterprises in the middle and low grade products of repeated production. Product three generation coexistence, in accordance with the output value, the first generation product market share of JG電機(jī)引接線second, the forty-five percent generation product market share of third, the fifteen percent generation of the product market share of forty percent. .
