APPLICATION
کابلهای N2XRY و N2XRH بخشی از طیف وسیع کابلهای برق فشارضعیف زرهدار برای انتقال و توزیع برق را تشکیل میدهند. این کابلها اغلب در انتقال برق در تمام صنایع کاربرد دارند .
افزودن زره SWA به این کابلها اجازه میدهد تا مستقیماً بدون محافظت اضافی در زمین دفن شوند و از آنها در برابر فشارهای مکانیکی و خطر آسیب ناشی از صدمات محیطی خارجی محافظت کند. روکش خارجی مشکی، محافظت در برابر اشعه ماوراء بنفش را برای استفاده در فضای باز فراهم میکند.
N2XRY یک کابل با روکش PVC است که با کابل استاندارد بریتانیا BS5467 قابل مقایسه است. کابل N2XRH از ترکیبات Low Smoke Zero Halogen (که با نام HFFR - بازدارنده شعله بدون هالوژن نیز شناخته میشود) استفاده میکند و با کابل BS6724 قابل مقایسه است.

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.
