300/500V塑料絕緣本質(zhì)安全防爆電路用集散型儀表信號電纜

Intrinsically safe explosion-proof circuit distributed type instrument signal cable

該產(chǎn)品為低電容、低電感集散型儀表信號電纜，具有優(yōu)異的屏蔽性能和抗干擾性能，它不僅可靠地傳輸微弱模擬信號和數(shù)字信號，而且防爆安全性能明顯高于一般DCS電纜和計算機控制電纜。廣泛用于化工、電力、煤氣工程和礦山等存在爆炸危險的場合以及其它的防爆安全要求較高的場合，傳輸自動控制信號。

The product is low capacitance, low inductance, distributed type instrument signal cable with perfect shield and anti-interference performance. It can reliably transmit feeble analog signal and digital signal, and its explosion-proof safety is prominently better than general DCS cable and computer cable. The product is widely used to transmit auto-control signals in the places where exist explosion danger such as chemical, power, coal gas engineering and mine, etc., or other places where require higher explosion-proof safety.

一、使用特性 Scope of application

1、交流額定電壓U₀/U 為300/500V。

Rated A.C. voltage U₀/U is 300/500V.

2、導(dǎo)體線芯最高工作溫度70⁰C、105⁰C、135⁰C三種。

The maximum long-term operating temperature of the conductor is 70⁰C, 105⁰C, 135⁰C.

3、最低環(huán)境溫度：固定敷設(shè)：-40⁰C，非固定敷設(shè)-20⁰C。

The lowest ambient temperature: it is -40⁰C for fixed laying and -20⁰C for non-fixed laying.

4、電纜允許最小彎曲半徑：非鎧裝電纜不小于電纜外徑的6倍，

銅帶屏蔽或鎧裝電纜不小于電纜外徑的12倍。

The minimum bending radius: it is not less than 6 times the outer diameter of the cable for non-armored cable and it is not less than 12 times the outer diameter of the cable for copper tap shielded or metal armored cable.
