通(tong)常(chang)所說的(de)網(wang)線(xian)學(xue)名(ming)叫雙絞(jiao)(jiao)線(xian)。雙絞(jiao)(jiao)線(xian)是(shi)組建(jian)局域網(wang)時常(chang)用的(de)一種傳(chuan)輸介質(zhi)，它(ta)由兩(liang)根具(ju)有(you)絕緣保(bao)護層的(de)銅導(dao)線(xian)組成。每兩(liang)根按一定的(de)密度纏絞(jiao)(jiao)在(zai)一起(qi)，這樣，在(zai)傳(chuan)輸電(dian)(dian)(dian)(dian)信(xin)(xin)號(hao)時相互之(zhi)間(jian)輻(fu)射出的(de)電(dian)(dian)(dian)(dian)波(bo)就會相互抵消(xiao)，可以(yi)有(you)效的(de)消(xiao)除干擾。既(ji)然(ran)網(wang)線(xian)是(shi)靠電(dian)(dian)(dian)(dian)信(xin)(xin)號(hao)傳(chuan)導(dao)工作的(de)，那(nei)么(me)一定要有(you)電(dian)(dian)(dian)(dian)能供(gong)應才(cai)能保(bao)證(zheng)通(tong)信(xin)(xin)正常(chang)進行。網(wang)線(xian)雖然(ran)有(you)電(dian)(dian)(dian)(dian)，但是(shi)要對人體造成傷(shang)害(hai)，它(ta)其實很“無辜”。網(wang)線(xian)里傳(chuan)送的(de)是(shi)電(dian)(dian)(dian)(dian)信(xin)(xin)號(hao)，電(dian)(dian)(dian)(dian)壓(ya)(ya)極低。其最高電(dian)(dian)(dian)(dian)壓(ya)(ya)為弱電(dian)(dian)(dian)(dian)3伏左右(you)，遠(yuan)遠(yuan)低于人體的(de)安(an)全(quan)電(dian)(dian)(dian)(dian)壓(ya)(ya)36伏，因此不(bu)會對人體造成傷(shang)害(hai)。在(zai)生活中(zhong)，我們為了保(bao)證(zheng)電(dian)(dian)(dian)(dian)信(xin)(xin)設(she)備(bei)的(de)穩定運行，不(bu)因斷(duan)(duan)電(dian)(dian)(dian)(dian)而影響通(tong)信(xin)(xin)，這些網(wang)絡設(she)備(bei)往往通(tong)過單(dan)獨(du)的(de)線(xian)路供(gong)電(dian)(dian)(dian)(dian)，或者安(an)裝有(you)不(bu)間(jian)斷(duan)(duan)電(dian)(dian)(dian)(dian)源。總之(zhi)，當生活用電(dian)(dian)(dian)(dian)中(zhong)斷(duan)(duan)時，它(ta)們可以(yi)通(tong)過其他電(dian)(dian)(dian)(dian)源獲得電(dian)(dian)(dian)(dian)能，繼續正常(chang)工作。
