聚氨酯拖鏈電纜與普通拖鏈電纜的區(qū)別就是外護套材料換成聚氨酯材料,使電纜更加耐彎曲、耐折、耐磨、耐油,用于連續(xù)往復(fù)運動下的移動使用。聚氨酯拖鏈電纜組成成分:
導(dǎo)體:精細(xì)無氧裸銅絲,多股絞合;
絕緣:高強度進口PE材料;
內(nèi)護套:高強度特種復(fù)合護套專用材料;
屏蔽:防氧化鍍錫銅網(wǎng)編織屏蔽,編織密度≥85%以上,可有效防止來自內(nèi)部和外部的干擾;
外護套:高強度進口PUR材料;
護套顏色:灰色,黑色,橙色,綠色;
額定電壓:<0.5mm,300/300V;≥0.5mm,300/500V;
使用溫度范圍:固定安裝:-40℃~80℃;移動使用:0℃~70℃;
最小彎曲半徑:固定安裝:5X電纜外徑;移動使用:7.5X電纜外徑;
聚氨酯拖鏈電纜應(yīng)用于數(shù)控機床,立車,玻璃機械,木工機械,機器人機械手,切割機,雕刻機,門窗機械等多種自動化機械設(shè)備。
二、聚氨酯拖鏈電纜特性
1、耐磨性:聚氨酯材質(zhì)具有高耐磨損性能,替代丁腈護套拖鏈電纜線適用于高耐磨環(huán)境;
2、耐油性:對于長時間接觸或浸泡油污的環(huán)境下的電纜,特別是具有腐蝕性的油污,聚氨酯護套的拖鏈電纜線滿足需求,且可在這樣的環(huán)境下長時間移動彎曲使用,其性能是常規(guī)丁腈材質(zhì)護套電纜不可替代的;
3、防水性:對于長時間接觸水或者直接浸泡在水中,如應(yīng)用于遠(yuǎn)洋水下設(shè)備的高柔性電纜,以防海水專用聚氨酯材質(zhì)作為護套,防水性能優(yōu)異,耐水解;

聚氨酯拖鏈電纜型號就是根據(jù)通用拖鏈電纜型號表示,只不過為了區(qū)分普通拖鏈電纜型號在后面加PUR(聚氨酯)例如:
TRVV-PUR:銅芯聚氨酯護套拖鏈電纜,一般有(2-14)*(4-6)mm2、(2-61)*(0.75-2.5)mm2近六十余種規(guī)格;
TRVVP-PUR:銅芯聚氨酯護套、軟護套鍍錫銅絲網(wǎng)編織屏蔽拖鏈電纜,一般有(7-61)*(0.75-1.5)mm2近五十余種規(guī)格;
