漆包(bao)線不同品(pin)種(zhong)的發(fa)展

縮醛漆包線

縮(suo)(suo)醛(quan)(quan)漆包線是世界(jie)上(shang)發展zui早的(de)品種之(zhi)一，1930年(nian)已由德(de)國(guo)、美國(guo)分(fen)別投放市場，蘇聯也(ye)發展很快，有聚(ju)乙(yi)烯(xi)醇縮(suo)(suo)甲醛(quan)(quan)和聚(ju)乙(yi)烯(xi)醇縮(suo)(suo)乙(yi)quan兩種，銅包鋁(lv)(lv)電線，我國(guo)也(ye)在60年(nian)代研究(jiu)成功(gong)。該(gai)漆包線雖(sui)耐(nai)(nai)溫(wen)等級低(105°C，120°C)，但由于其具有優(you)良的(de)耐(nai)(nai)高溫(wen)水解性(xing)能而(er)廣泛的(de)應(ying)用于油浸變(bian)壓器(qi)中，銅包鋁(lv)(lv)，這一特性(xing)得(de)到了(le)的(de)公證，我國(guo)目前仍(reng)有少量(liang)生(sheng)產，特別是縮(suo)(suo)醛(quan)(quan)漆包扁線用來制作(zuo)換位(wei)導線，用于大型變(bian)壓器(qi)中? ?。

性能

由于高頻信號具有“趨膚效應”的(de)特(te)點，因此(ci)銅(tong)(tong)(tong)(tong)包(bao)鋁線(xian)和銅(tong)(tong)(tong)(tong)包(bao)鋼線(xian)在(zai)傳輸高頻信號（大于5MHz）時，具有與純銅(tong)(tong)(tong)(tong)線(xian)相同的(de)導電(dian)(dian)性(xing)(xing)(xing)(xing)能(neng)(neng)。du的(de)復(fu)合(he)性(xing)(xing)(xing)(xing)能(neng)(neng)：銅(tong)(tong)(tong)(tong)包(bao)鋁線(xian)同時具備(bei)銅(tong)(tong)(tong)(tong)的(de)導電(dian)(dian)性(xing)(xing)(xing)(xing)與鋁的(de)密度(du)小的(de)復(fu)合(he)特(te)性(xing)(xing)(xing)(xing)；而(er)銅(tong)(tong)(tong)(tong)包(bao)鋼線(xian)則將銅(tong)(tong)(tong)(tong)的(de)導電(dian)(dian)性(xing)(xing)(xing)(xing)與鋼的(de)高強度(du)結(jie)合(he)在(zai)一(yi)起。鍍錫銅(tong)(tong)(tong)(tong)包(bao)鋼線(xian)發揮了錫的(de)可焊性(xing)(xing)(xing)(xing)和抗硫化(hua)性(xing)(xing)(xing)(xing)；鍍銀(yin)銅(tong)(tong)(tong)(tong)包(bao)鋼線(xian)則提高了導電(dian)(dian)性(xing)(xing)(xing)(xing)、導熱性(xing)(xing)(xing)(xing)、增大了耐(nai)蝕性(xing)(xing)(xing)(xing)、抗yang化(hua)性(xing)(xing)(xing)(xing)。因而(er)具有廣闊的(de)應用范圍。
