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

Each low voltage 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 LOW VOLTAGE 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:

• 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?

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.

• R 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 (low voltage)

Another example of the acronym’s meaning can be found with the Top Cable Powerhard RMV cable 0,6 / 1kV 3×2,5 UNE 21123 IEC 60502 CE 1201416; which is the following:

• Top cable: Manufacturer
• POWERHARD: Trade name
• RVMV: Cable insulated with PLXLPE (R), with OVC (V) seat, armoured with steel wire core (M) and covered with PVC (V)
• 0,6 / 1kV: The nominal voltage of the cable is 1000V (low voltage)
• 3×2,5: Three-wire cable 2.5 mm² without am-green
• UNE 21123 IEC 60502: Cable design standards. These standards define exactly what the cable looks like. Thicknesses, material qualities, tests to be carried out, etc. UNE 21123 is the Spanish design standard. IEC 60502 is the standard on which UNE 21123 is based
• CE: CE marking obligatory for the marketing of the product in the European Community. This marking can be on the product or on the packaging
• 090102: Date of manufacture for traceability

 LOW VOLTAGE 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

Screen designation, interior lining, armature seat

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

Designation of the different types of armor

Designation of the outer sheath

Conductor’s designation

Rated voltage

Explanation of the number of conductors

Cable design rules

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

• UNE 21123
• IEC 60502
• UNE 21150
