Low voltage cable is used for power transmission in distribution lines, power stations, lighting systems, power transmission to electric motors and…. These cables are also used in public and industrial networks, indoor and outdoor installations, buried in the ground or inside the canal..
Basically, low voltage cable consists of different parts, which are conductor, insulation, insulation shell, conductor shell, metal shell, and each has its own characteristics.. If you want to choose a cable that exactly fits your needs, you should pay attention to things like material and number of conductors, conductor cross section, insulation materials.. Conductors are fixed cables that have no flexibility at all or are flexible and flexible cables.. Each of these cables has a different class, each with its own characteristics, for example, mobile cables consisting of two classes. 5 And 6 Are that class 6 Much more than class 5 It has flexibility.
Construction of low voltage cables and standard sizes
Low voltage cables (Up to 1000 volts) Nowadays, without copper conductor and insulation used wire is used in places where the risk of mechanical damage is low, armored cable is used and in places where there is a risk of mechanical damage, cable with protective armor is used..
Characteristic signs of cables
In the German standard that is common in Iran Cable construction It is indicated by the letters of the alphabet. In this method, the first letter indicates the conductor material, N indicates copper and NA indicates aluminum, the second letter indicates the insulation of the wires.. Y is a plastic symbol and G is a rubber symbol, and if there is no letter, paper insulation is desired..
Symptoms of the type of pods
Y plastic sheath
K sheath series
KL aluminum sheath
Armor type markers
B Identifier of steel wires
Gb Determinant of galvanized steel wire
And the last part identifies the material of the outer covering, in which A identifies the plant fibers (jute) is.

قیمت کابل فشارضعیف
اگر قصد خرید کابل فشار ضعیف یا خرید کابل ولتاژ پایین را دارید باید پامترهای زیادی را مد نظر داشته باشید. توجه کنید که وزن و جرم کابل به هیچ عنوان معیار مناسبی برای تشخیص کیفیت کابل نیست. علاوه بر آن قیمت کابل فشارضعیف هم نمی تواند معیار خوبی برای اصالت کابل باشد چراکه فروشندگانی هستند که با قیمت گذاری کابل اصل روی کابل تقلبی کابل تقلبی را به جای کابل اصل به مشتری می فروشند. برای خرید کابل فشارضعیف تنها باید به فروشگاه های معتبر مراجعه کنید به دلیل اینکه اعتبار و سابقه فروشگاه همواره می تواند معیار مناسبی برای خرید کابل فشار ضعیف باشد.
