一、適用范圍

本產(chǎn)品適用于石油、化工、電力、煤氣工程、礦山等存在爆炸危險(xiǎn)的場(chǎng)合以及其它防爆安全要求較高的場(chǎng)合，傳輸自動(dòng)控制信號(hào)。該電纜具有低電容、低電感集散型儀表信號(hào)電纜，簡(jiǎn)稱本安型DCS電纜，具有優(yōu)異的屏蔽性能和抗干擾性能因此防爆安全性能明顯高于一般DCS電纜和計(jì)算機(jī)控制電纜。

Scope of application

It is used to transmit automatic control signal in the environmentnot only with exploding danger such as petroleum, chemical plant.power, gas project and mine but also with high demａnd on explosionproof performance.lt is decentralized type instrument signacable with the feature of low capacitance &low inductance& good shielding performance and interference proof performance.which is also named as Intrinsic safety type cable for DCS system.So, its performance of explosion-proof & safety is apparentlyhigher compared with common computer control cable and cablefor DSC.
