BS 6724, IEC/EN 60228, EN 50267-2-1, IEC/EN 60502-1, Flame Retardant according to IEC/EN 60332-1-2, IEC/EN 60332-3-24 Cat C Low Smoke Zero Halogen according to IEC/EN 60754-1/2, IEC/EN 61034-1/2
APPLICATION
کابل N2XRH ؛ با هادی از جنس مس و روکش از جنس LSZH (Low Smoke Zero Halogen) بوده و دارای زره فولادی (SWA) میباشد. این نوع کابلها جهت نصب در فضای داخلی و خارجی پروژه، در کانال های کابل حفرشده در زمین و همچنین کاربردهای زیرزمینی در شبکه های برق کاربرد دارد. به دلیل داشتن روکش LSZH به صورت خاص ، برای نصب در فضاهایی که انتشار گازهای سمی و دود ناشی از آتش سوزی برای انسان و تجهیزات مخاطره آمیزباشد ، طراحی شده اند.
کابلهای LSZH به طور کلی در شرایط آتشسوزی محافظت بیشتری ارائه میدهنند ، هیچ یک از گازهای هالوژن مضر مانند گاز کلر را منتشر نمیکنند و در مقایسه با کابلهای با روکش PVC، سطح کمتری از دود سیاه غلیظ منتشر میکنند. در نتیجه، کابل N2XRH به طور گسترده در ساختمانهای عمومی، سازههای بلند و همچنین در پالایشگاهها، کارخانههای اتوماسیون و مراکز داده - مناطقی که انتشار دود و گازهای سمی میتواند در صورت آتشسوزی خطری برای سلامت انسان و تجهیزات حساس ایجاد کند - استفاده میشود.

Conductor operating temperature: 90ºC r = Resistive Component x = Reactive Component z = Impedance Value
For cables having conductors of 16mm2 or less cross sectional area their inductances can be ignored and (mV/A/m)r values only are tabulated. For cables having conductors greater than 16mm2, cross sectional area the impedance values are given as (mV/A/m)z, together with the resistive component (mV/A/m)r and the reactive component (mV/A/m)x.
