Abbreviations in cables
All standard and reliable wires and cables have abbreviations. These signs provide product information to customers and sellers. This will help you make the right choice. For example, the signs engraved on the self-supporting cables are different from other cables, which indicates the differentiation of this product.
Cable abbreviations
The meaning and application of wire and cable abbreviations
Wires and cables are different from each other in things such as conductor, internal insulation, type of armor, wire size and thickness, amperage, etc. Therefore, various uses and uses have been defined for them. In order to avoid mistakes, there are abbreviations for sellers and buyers on cables and wires. By examining these signs, the application and structure of the product can be determined. Considering that checking these abbreviations is a specialized job, many customers leave it to the sellers, but it is necessary to be aware of this information during online shopping or in some emergency situations. For this reason, you should not simply skip learning them.
Abbreviations of wires and cables are determined according to valid international standards. These signs consist of several separate parts, including the structure of the layers, the cable conductor, the number of strands in each wire, the type of conductor, the cross-sectional area and the voltage. Each wire is made of different layers according to the international standard and according to the type of application, such as outer coating, middle insulation, separating coating, armor (used in some special cables), protection, conductive insulation and conductor. This structure may have additional layers or less layers.Wire and cable abbreviations
In checking wire and cable abbreviations, it is necessary to check the signs from left to right. The first symbol specifies the type of conductor or conductor of the cable. This section is responsible for the transmission of electricity and electricity flow. The second letter indicates the type of conductor, that is, the part responsible for protecting the cable. The third letter indicates the material used for the sheath of wire and cable. The fourth letter indicates the material of the final cover.
Wire abbreviations
The abbreviations mentioned on the wires are as follows.
1- NYA: Single layer wire with plastic coating, can be used for building wiring
2- NYAF: plastic-coated wire, can be used for building wiring
3-: NSYA special wire with plastic coating, can be used for building wiring
4- NYM: moisture resistant wire
5- NYZ: wire with plastic coating, can be used for lighting and household appliances
6- NYFA: wire for use in chandeliers and lights
7- NYFAZ: two-stranded wire, can be used for lighting purposes
8- Y: wire for conversation and news
9- T: coaxial wire
wire and cable
In these abbreviations, N stands for copper wire according to the German standard. The letter Y indicates the insulation of the protodoor. The letters z and s are used for special wires. Wires for indoor wiring are indicated by the letter A, soft wires by F, and moisture-resistant wires by M.
Cable abbreviations
Cables are placed in round and triangular categories based on their cross section. Abbreviations are for round cables r and triangular cables s. According to the number of strands used in them, the conductors of the cables are divided into two categories: wire and wire. The letter e is used to indicate the wire conductor and the letter m is used to indicate the sparking conductor.
In order to correctly distinguish the cables from each other, the insulation of the cable wires has been offered in different colors. These colors are in accordance with the VDE0271 standard of Germany and Iran as follows:
The insulation and conductor abbreviations used in cables are as follows:
1-N: Softened cable with copper conductor according to VDE standard
2-::NA softened cable with aluminum conductor according to VDE standard
3-Y (first in the row of letters): Protodo or PVC insulation
4- Y (second in the row of letters): sheath with Protodor or PVC cover
5- B: Cable armed with steel bandage or metal band
6- F: armored cable with flat wire
7- R: cable armed with round nails or tin-coated steel wire
8- Z: cable armed with profile wire
9- G: Strip-shaped steel protection
GB-10: strip-shaped steel shield or spiral steel belt (this shield is used to secure F armor or R armor)
11- C: cable with neutral wire
12- CW: concentric copper wire made of thin copper wire that is placed in a wave form around the cable.
13-: K cable with lead sheath
14-E: three lead sheath cable
15-H: Metallized sheet that is wrapped around the wire and insulation to limit the magnetic field.
16-T: cables with bearing wire and can be used in aerial cables
17-A: If it is not after the letter N, it indicates a double outer sheath
18-S: copper shield that is wrapped around the insulation in the form of a wide and thin belt.
19-SE: copper shielding for multi-core cables that limits the magnetic field instead of H metallized paper.
20-J: Cables suitable for earth, which are green-yellow in color.
