    一、KX-GS-VVP補(bǔ)償電纜特點(diǎn)及用途

        補(bǔ)償電纜由一定數(shù)量的對絞式補(bǔ)償線對或屏蔽補(bǔ)償線對絞合成纜,然后包覆屏蔽層、護(hù)套、鎧裝層等。其中各補(bǔ)償線對的型號、規(guī)格、級別和結(jié)構(gòu)尺寸一般是相同的,當(dāng)有特殊要求時(shí),亦可由不同的補(bǔ)償線對組成補(bǔ)償電纜。

    補(bǔ)償線對均采用絞合型式,屏蔽層按材料可分為銅線或鍍錫銅線編織屏蔽、鋁塑復(fù)合帶繞包屏蔽、銅塑復(fù)合帶繞包屏蔽、銅帶繞包屏蔽,按結(jié)構(gòu)可分為“總屏蔽”和“分對屏蔽加總屏蔽”的型式,可根據(jù)防干擾的要求選用。

    KX-GS-VVP補(bǔ)償電纜補(bǔ)償電纜用以延伸一定區(qū)域內(nèi)諸熱電偶的冷端與各顯示儀表連接構(gòu)成測溫系統(tǒng)。

    本質(zhì)安全防爆測溫系統(tǒng)用熱電偶補(bǔ)償電纜是由多對本質(zhì)安全防爆測溫系統(tǒng)用補(bǔ)償導(dǎo)線組合而成的電纜。其特征與本質(zhì)安全防爆系統(tǒng)用補(bǔ)償導(dǎo)線相同。

    本安補(bǔ)償電纜用于將多個(gè)防爆熱電偶冷端延伸一定距離與顯示儀表連接構(gòu)成本質(zhì)安全防爆測溫系統(tǒng)。

     

    Ⅰ. Characteristics and application

    It is stranded with a certain number of twisted extension wire pairs or shield extension wire pairs, covered with shield layers, sheathed and armoured layers. The type, specification, class and structure sizes of extension wire pairs are generally same. When a special requirement is given, the cable can also be formed by different extension wire pairs.

    There are many kinds of shield for twisted extension wire pairs such as copper wire or tin plated copper wire braid shield, composite aluminium-plastic tapes wrap shield, composite copper-plastic tape wrapped shield, copper tapes shield, “general shield” and “sub plus general shield ”. It is possible to select the shield according to requirements of interference prevention.

    Extension Cable is used to extend cold clamps of thermocouple and connects them with instruments, which forms temperature-testing system.

    Extension Cable used in thermocouple for intrinsically safe explosion-proof temperature testing system consists of multiple-pairs of extension wire. In that case, the characteristics of the cable are just the same as those of the wire used for intrinsically safe explosion-proof temperature testing system.

    Intrinsically safe extension cable extends cold clamps of explosion-proof thermocouple for a certain distance to connect instruments, which forms intrinsically safe explosion-proof temperature-testing system.
