Low voltage electrical cable’s designations (0.6 / 1 KV)


Each cable has a designation according to the norm. This denomination is composed by a set of letters and numbers, each with a specific meaning. This designation refers to a series of product characteristics (materials, nominal voltages, etc.) that facilitate the most suitable cable selection for your needs, avoiding possible errors in the cable supply.

When a cable does not indicate this data clearly, it may be a faulty cable, which does not meet the safety standards or its proper functioning.

INDUSTRIAL POWER CABLES 0.6 / 1KV

Industrial power cables  0.6 / 1kV are for industrial power applications in various fields (general industry, public facilities, infrastructures, etc.), and international standards: UNE, IEC, BS, UL.

Some low voltage power examples cables 0.6 / 1kv are the following:

Cables de Baja Tensión de potencia 0,6/1kv

  • THE ACRONYM MEANINGS FOR THE COMMERCIAL CABLE’S NAME

What does it mean, for example, RZ1-K on a Top Cable Toxfree ZH RZ1-K cable?

cable Toxfree RZ1-K (AS)

After the manufacturer name (in this case, Top Cable) and the Trademark (Toxfree), the letters and numbers refer to the coatings of the cable, the conductor class, to the nominal voltage and to the composition end of the cable.

  • is the insulation type, in both cases, is Reticulated Polyethylene (XLPE).
  • Z1 indicates that this cable has a polyolefin cover not flammable, halogen-free and with low smoke emission and corrosive gases in case of fire. Its designation is Z1.
  • K the letter K indicates that it is a flexible copper conductor (class 5), for fixed installations.

0.6 / 1 kV indicates that it is a 1000-volt cable

CABLE DENOMINATION 0.6 / 1kV

Each cable has a standard designation. This designation is composed of a set of letters and numbers, each with a specific meaning. This designation refers to a series of product characteristics (materials, nominal tensions, etc.) that facilitate the selection of the most suitable cable for your needs, avoiding possible errors in the supply of one cable by another.

When a cable does not clearly indicate these data, it may be a defective cable, which does not comply with safety regulations or guarantee the cable’s life and proper operation.

The meaning of each letter within each section is as follows:

Designation according to type of insulation

nomenclature Cable type
R Crosslinked polyethylene (XLPE)
X Cross-linked polyethylene (XLPE)
Z1 Halogen-free thermoplastic polyolefin
Z Halogen-free thermosetting elastomer
V Polyvinyl chloride (PVC)
S Halogen-free thermosetting silicone compound
D Ethylene-propylene elastomer (EPR)

Screen designation, interior lining, armature seat

nomenclature Cable type
C3 Copper wire screen, helically arranged
C4 Copper shield in the form of a braid, on the assembled insulated conductors.
V Polyvinyl chloride (PVC)
Z1 Halogen-free thermoplastic polyolefin

If there is no screen, no inner lining and no armature seat, no letter is used.

Designation of the different types of armor

nomenclature Cable type
F Steel strapping arranged in a helical pattern.
FA Aluminium strapping arranged in a helical pattern
FA3 Longitudinally corrugated aluminium strip
M Steel wire crown
MA Aluminium wire crown

Designation of the outer sheath

nomenclature Cable type
V Polyvinyl chloride (PVC)
Z1 Halogen-free thermoplastic polyolefin
Z Halogen-free thermosetting elastomer
N Vulcanized chlorinated polymer

Conductor’s designation

nomenclature Cable type
K Flexible copper (class 5) for fixed installations
F Flexible copper (class 5) for mobile services
D Flexible for welding machine cables. When there are no letters on it, the conductor is made of solid copper, class 1 or 2.
AL AL If the conductor is made of aluminium, (AL) is indicated.

Tensión nominal

Rated voltage
0,6/1 kV Rated voltage 1,000V

Explanation of the number of conductors

nomenclature Cable type
nGS Number and cross-section of wires, in mm2 , with Yellow/Green conductor
nxS Number and cross-section of conductors, in mm2 , without conductor Yellow/Green

Cable design rules

The cable design rules are also referenced in the marking of each cable:

  • UNE 21123
  • IEC 60502
  • UNE 21150

Additional data

nomenclature Cable type
CE CE CE marking is compulsory for the marketing of the product in the European Community. This marking can be on the product or on the packaging.
Manufacture date Date of manufacture (YYMMDD). The date of manufacture is usually placed for traceability purposes. Traceability makes it possible to know who, when and where has carried out each stage of the process and with which materials.
