一、概述

  熱電偶補償導(dǎo)線、補償電纜的作用是來延伸熱電極即移動熱電偶的冷端,與顯示儀表聯(lián)接構(gòu)成測溫系統(tǒng)。本產(chǎn)品等效采用等效采用IEC 584-3《熱電偶第三部分-補償導(dǎo)線》,產(chǎn)品質(zhì)量優(yōu)于GB 4989-85《熱電偶用補償導(dǎo)線》國家。絕緣層和護層選用進口優(yōu)質(zhì)氟塑料,并采用整體連續(xù)擠出新工藝,使該產(chǎn)品具有優(yōu)良的耐酸、堿、耐磨和不燃延之性能,可浸入油水中長期使用。使用溫度—60—205—260℃,屬于當代較高水平。熱電偶補償導(dǎo)線、補償電纜主要應(yīng)用于各種測溫裝置,已被廣泛用于石油、化工、冶金、電力等部門。

 

二、主要技術(shù)指標

   1、補償導(dǎo)線型號按產(chǎn)品的品種劃分為:SC、KC、KX、EX、JX、TX、NC

   2、其中:a)型號*個字母與熱電偶的分度號相對應(yīng);

   b)字母“X”表示延伸型補償導(dǎo)線(型別);

   c)字母“C”表示補償型補償導(dǎo)線(型別)。

   注:SC型補償導(dǎo)線可配用R型分度號熱電偶

三、型號表示

 

    示例:配K型偶補償導(dǎo)線,單線標稱截面1.5mm2

   ●一般用普通級補償型補償導(dǎo)線表示為;KC-GB-VV-2*1.5

   ●耐熱用精密級屏蔽補償型補償導(dǎo)線表示為:KC2-HA-FFP-2*1.5

   ●耐熱用精密級屏蔽軟線延伸型補償導(dǎo)線表示為:KX-HA-FFRP-2*1.5

   注:1、補償導(dǎo)線成品的線芯間和線芯與屏蔽間的絕緣電阻,在溫度為20℃時每10米不小于5MΩ。

        2、補償導(dǎo)線成品耐熱老化溫度在275℃/24小時前后進行5倍外徑的卷繞試驗,經(jīng)電壓500 v/1分種不擊穿。

        3、耐熱用補償導(dǎo)線的防水試驗,從成品中取出1.5m的試樣端部外露放入40±2℃的恒溫器中,經(jīng)240小時(10)天后,導(dǎo)線線芯間和線芯與屏蔽間每米電阻值不小于25MΩ。

        4、耐熱用補償導(dǎo)線的耐酸試驗,從成品中取出1.5m試樣端部外露放入40±2℃,95%濃度的硫酸溶液中,經(jīng)240小時(10)天后,導(dǎo)線線芯間和線芯與屏蔽間每米電阻值應(yīng)不小于25MΩ。

        5、補償導(dǎo)線技術(shù)條件符合IEC 584-3,一般用的符合GB4989-85。
