Meaning of Cable types NYY, NYA, NYM, NYFGbY, etc, "Cable Nomenclatures"


What is the meaning of Cables Code, NYY, NYA, NYAF, NGA, NYM, NYMhY, NYFGbY, NFA, AAAC, and many others.
Meaning letter code of electrical cable
Know the meaning of the LETTER code on the power cord, In electrical installations at home, the cable that we usually use is NYA cable or NYM cable, Or if we need a type of cable for underground installation (planting cable), the suitable cable is the NYFGbY cable.

Then, have we ever asked, what exactly is the meaning of the letter code on the cable?
What is the meaning of "NYA" Cables?
NYM cable, what does NYM mean?
NYFGbY code on cable, what do you mean?

Of course each letter code on each type of cable has its own meaning, For this reason, this time we will try to share the meaning of the letter code on the power cable.

Giving this letter code, commonly referred to as Cable Nomenclature.

Cables Nomenclature

A. Copper Cable types

NYA
  • N = Copper core cable
  • Y = PVC Insulation
  • A = Single cable
NYA cable is a cable with a single copper core, one layer PVC insulated (450v-750v)


NYAF
  • N = Copper core cable
  • Y = PVC Insulation
  • A = Single cable
  • F = Fine wire conductor (fibers)
NYAF cable is a cable with a fiber copper core (Flexible), with a single core (one), one layer PVC insulated (450v-750v).


NGA
  • N = Copper core cable
  • G = Rubber insulation
  • A = Single cable
NGA cable is a cable with a single copper core with rubber-based insulation.


NYM
  • N = Copper core cable
  • Y = PVC Insulation
  • M = more than one cable core
NYM cable is a cable with a PVC insulated copper core, with more than one core, and PVC insulated on the outside (300v-500v).


NYMHY
  • N = Copper core cable
  • Y = PVC Insulation
  • M = more than one cable core
  • H = Flexible Cable (Fiber)
  • Y = PVC Outer Insulation
NYMHY cable is a cable with a fiber copper core (Flexible Copper) PVC insulated, with more than one cable core and sheathed PVC insulation (300v-500v)


NYY
  • N = Copper core cable
  • Y = PVC Insulation
  • Y = PVC Outer Insulation
NYY cable is a cable with a PVC insulated copper core, with a single or more than one core cable, with a PVC outer sheath (0.6kv-1kv).


NYYHY
  • N = Copper core cable
  • Y = PVC Insulation
  • Y = PVC Insulation
  • H = Flexible Cable (Fiber)
  • Y = PVC Outer Insulation
NYYHY cable is a cable with a fiber copper core (flexible copper) PVC insulated, with a single core or more than one, and PVC outer sheath (0.6kv-1kv).


NYRGbY
  • N = Copper core cable
  • Y = PVC Insulation
  • R = Round steel wire guard
  • Gb = Steel plate
  • Y = PVC Insulation
NYRGbY cable is a cable with a PVC insulated copper core, with a single core or more than one, round steel wire protector or steel plate wrapped, with a PVC insulating sheath. (0.6kv-1kv).


NYFGbY
  • N = Copper core cable
  • Y = PVC Insulation
  • F = Flat steel wire guard
  • Gb = Steel plate
  • Y = PVC Insulation
NYFGbY cable is a cable with a PVC insulated copper core, with more than one core, protected by flat steel plates or wrapped around a steel plate, with a PVC insulating sheath (0.6kv-1kv).


B. Aluminum Cable types

NFA
Aluminum core cable for air network installation


NFA 2X
Aluminum core cable for mounting air networks with XLPE insulation (> 20kv).


NFA 2X-T
Aluminum core cable for mounting air networks, with XLPE insulation (> 20kv). with hanging wire.


AAAC
All Aluminum Alloy Conductor
AAAC cable is a cable with an aluminum core that is twisted, has a strong attraction, and rust resistance.


Note:
The letter code on the power cable is also determined in the laying of the letter. Differences in the location of letters can distinguish the meaning.

Example: The letter F code on the NYAF cable is in the position of the fourth letter (last) means a fine wire cable, while the letter F on the NYFGbY is in the third letter meaning Flat Steel Wire Protector.


Cable size
In electrical wires, we can also find codes, such as NYY 4 x 4mm².

This number code means that the NYY cable has 4 cores, and the cross-sectional area of ​​each cable is 4 mm².

Or, on aluminum cables there are numeric codes such as NFA 2X-T (3 x 70mm² + 1 x 50mm².
This means that the cable has 4 cables, with a cross section size of 3 cables of 70mm² (as a phase cable), and 1 cable with a section size of 50mm² (as a Neutral cable).
