What is the important of Cables Code, NYY, NYA, NYAF, NGA, NYM, NYMhY, NYFGbY, NFA, AAAC, together with many others.
Meaning missive of the alphabet code of electrical cable
Know the important of the LETTER code on the ability cord, In electrical installations at home, the cable that nosotros ordinarily run is NYA cable or NYM cable, Or if nosotros demand a type of cable for surreptitious installation (planting cable), the suitable cable is the NYFGbY cable.

Then, accept nosotros always asked, what just is the important of the missive of the alphabet code on the cable?
What is the important of "NYA" Cables?
NYM cable, what does NYM mean?
NYFGbY code on cable, what create you lot mean?

Of class each missive of the alphabet code on each type of cable has its ain meaning, For this reason, this fourth dimension nosotros volition endeavour to part the important of the missive of the alphabet code on the ability cable.

Giving this missive of the alphabet code, commonly referred to equally Cable Nomenclature.

Cables Nomenclature

A. Copper Cable types

NYA
  • N = Copper amount cable
  • Y = PVC Insulation
  • A = Single cable
NYA cable is a cable amongst a unmarried copper core, i layer PVC insulated (450v-750v)


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


NGA
  • N = Copper amount cable
  • G = Rubber insulation
  • A = Single cable
NGA cable is a cable amongst a unmarried copper amount amongst rubber-based insulation.


NYM
  • N = Copper amount cable
  • Y = PVC Insulation
  • M = to a greater extent than than i cable core
NYM cable is a cable amongst a PVC insulated copper core, amongst to a greater extent than than i core, together with PVC insulated on the exterior (300v-500v).


NYMHY
  • N = Copper amount cable
  • Y = PVC Insulation
  • M = to a greater extent than than i cable core
  • H = Flexible Cable (Fiber)
  • Y = PVC Outer Insulation
NYMHY cable is a cable amongst a fiber copper amount (Flexible Copper) PVC insulated, amongst to a greater extent than than i cable amount together with sheathed PVC insulation (300v-500v)


NYY
  • N = Copper amount cable
  • Y = PVC Insulation
  • Y = PVC Outer Insulation
NYY cable is a cable amongst a PVC insulated copper core, amongst a unmarried or to a greater extent than than i amount cable, amongst a PVC outer sheath (0.6kv-1kv).


NYYHY
  • N = Copper amount cable
  • Y = PVC Insulation
  • Y = PVC Insulation
  • H = Flexible Cable (Fiber)
  • Y = PVC Outer Insulation
NYYHY cable is a cable amongst a fiber copper amount (flexible copper) PVC insulated, amongst a unmarried amount or to a greater extent than than one, together with PVC outer sheath (0.6kv-1kv).


NYRGbY
  • N = Copper amount cable
  • Y = PVC Insulation
  • R = Round steel wire guard
  • Gb = Steel plate
  • Y = PVC Insulation
NYRGbY cable is a cable amongst a PVC insulated copper core, amongst a unmarried amount or to a greater extent than than one, circular steel wire protector or steel plate wrapped, amongst a PVC insulating sheath. (0.6kv-1kv).


NYFGbY
  • N = Copper amount cable
  • Y = PVC Insulation
  • F = Flat steel wire guard
  • Gb = Steel plate
  • Y = PVC Insulation
NYFGbY cable is a cable amongst a PVC insulated copper core, amongst to a greater extent than than i core, protected yesteryear apartment steel plates or wrapped only about a steel plate, amongst a PVC insulating sheath (0.6kv-1kv).


B. Aluminum Cable types

NFA
Aluminum amount cable for air network installation


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


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


AAAC
All Aluminum Alloy Conductor
AAAC cable is a cable amongst an aluminum amount that is twisted, has a rigid attraction, together with rust resistance.


Note:
The missive of the alphabet code on the ability cable is too determined inwards the laying of the letter. Differences inwards the place of letters tin laissez passer notice distinguish the meaning.

Example: The missive of the alphabet F code on the NYAF cable is inwards the seat of the quaternary missive of the alphabet (last) agency a fine wire cable, spell the missive of the alphabet F on the NYFGbY is inwards the 3rd missive of the alphabet important Flat Steel Wire Protector.


Cable size
In electrical wires, nosotros tin laissez passer notice too honour codes, such equally NYY 4 x 4mm².

This pose out code agency that the NYY cable has 4 cores, together with the cross-sectional surface area of ​​each cable is 4 mm².

Or, on aluminum cables in that place are numeric codes such equally NFA 2X-T (3 x 70mm² + 1 x 50mm².
This agency that the cable has 4 cables, amongst a cross department size of iii cables of 70mm² (as a stage cable), together with 1 cable amongst a department size of 50mm² (as a Neutral cable).
