Types of cables

An electric cable has the

purpose of transporting electrical energy from one point to another. Depending on their

final application, cables can have different configurations, always basing their design

on national and international regulations.

Low voltage cables (up to 750 V): in a variety of applications, and with

thermoplastic and thermoset coatings. They are designed and built according to harmonized


Low Voltage cables (up to 1,000 V): (also called (0,6/1 kV) The cables in this

section are used for industrial power installations in various fields (general industry,

public installations, infrastructures, etc.). They are designed according to

international standards (UNE, IEC, BS, UL).

Medium Voltage cables: from 1 kV to 36 kV. They are used to distribute electricity

from electrical substations to transformer stations.

High Voltage cables: from 36 kV. They are used to transport electricity from the

generating plants to the electrical substations.

Types of electric cable by their use

Low voltage cables

Cables for electric panels

Flexible cables for wiring electric cabinets. These electric cables are especially

suitable for domestic use, for installation in public places and for internal wiring of

electrical cabinets, switch boxes and small electrical appliances.

Power cables

Energy cables for industrial facilities and public places. It is common to find

power cable in applications for power

transmission in all types of low voltage connections, for industrial use and for variable

frequency drive (VFD).

Armoured cables

Cables with aluminium or steel reinforcement for installations with risk of

mechanical aggression. It is also common to find armoured cables in places where rodents

are present, as well as in installations in premises with a risk of fire and explosion


Rubber cables

The use of extra flexible rubber cable

is very varied. We can find rubber cables in fixed industrial installations as

well as in mobile service. Welding cables should have a rubber sheath, which allows high

currents to be transmitted between the welding generator and the electrode.

Halogen-free cables

High Security Halogen Free (LSZH) Cables with low smoke and corrosive gas emission in

case of fire are suitable for use in wiring of electrical panels and public places,

installations of all kinds in public places, individual derivations, emergency circuits,

public distribution networks and also for mobile service.

Fire resistant cables

These cables are specially designed to transmit electrical energy in the extreme

conditions that occur during a prolonged fire, guaranteeing supply to emergency equipment

such as signalling, smoke extractors, acoustic alarms, water pumps, etc. Their use is

recommended in emergency circuits in places with public concurrence.

Control cables

Control cable for

fixed or mobile installations should be extremely flexible, as they are mainly designed

for small household appliances, for the interconnection of machine parts used for

manufacturing, for signalling and control systems, for the connection of motors or

frequency converters, for signal transmission where the voltage induced by an external

electromagnetic field may affect the transmitted signal or for power supply connections

to avoid generating electromagnetic fields.

Instrumentation cables

These are flexible and shielded cables for the transmission of signals between

equipment in industrial installations. Especially suitable for optimum data transmission

in environments with a high level of electromagnetic interference.

Solar cables

These cables are particularly suitable for connecting photovoltaic panels, and from

the panels to the DC to AC inverter. Thanks to the design of their materials and their

cover, which is especially resistant to solar radiation and extreme temperatures, they

can be installed outdoors with full guarantees.

Special cables

There is a wide variety of electric cables for special installations such as:

temporary light garland installations at trade fairs; connections for overhead cranes,

hoists and lifts; applications in submerged pumps and drinking water areas such as

aquariums, purification systems, drinking water fountains or in swimming pools for

lighting, purification and cleaning systems.

PVC Cables or PUR Cables: How to Choose the Right Cable

Cables are an essential part of any industrial application. It is important

to make sure that you choose the appropriate cable material for the environment,

especially where chemical cleaning solutions, cutting fluids, and other caustic liquids

are present. The two main types of cables used in industrial applications are either PVC

or PUR, and they are each suited to different types of environments. This article

describes the difference between PVC and PUR cables and when to use each type of cable.

PVC Cables and When to Use Them

PVC cable is Polyvinyl Chloride (PVC) cables that is sheathed and

insulated. PVC cables are an excellent choice for most chemical washdown applications in

the food industry and beverage industry. They have good-to-excellent resistance to

common cleaning solvents including, but not limited to:

Sodium Hypochlorite

Sodium Hydroxide

Potassium Hydroxide

Peracetic Acid

Hydrogen Peroxide

Quaternary Ammonium Compounds

It is also important to take into consideration the concentration of

chemicals, temperatature of the process, and the duration and frequency of exposure since

these factors can impact the suitability of PVC for these applications. Furthermore, PVC

has limited resistance to oils, making it less suited for automotive and machine tool


In addition to being resistant to common cleaning chemicals, PVC cables are

generally more rigid than other types of cables. This makes them suitable for use in

applications where they will be exposed to high temperature, high pressure washdown. The

rigidity of the PVC sheathing protects the cable from damage and extends the life of the


A PVC cable with IP69K rating means it is sealed against the ingress of water

even during washdown. However, the rigidity of PVC cables can be a disadvantage in

freezer applications, where low temperatures can cause the material to crack if the

cables are being flexed. Discuss your specific application with an expert to determine

the best cable material in these circumstances.

PUR Cables and When to Use Them

PUR (or polyurethane) is a thermoplastic material used for cable jackets.

Because PUR cables are resistant to cutting fluids, oils, and other harsh chemicals, they

are a good choice for many automotive manufacturing

, stamping and machining applications.

PUR cables also have high tensile strength, tear resistance, and abrasion

resistance. They are also extremely flexible, with a small bend radius. This makes them

ideal for applications where connections move or bend frequently, such as robotic


What do you mean by XLPE cable and what are its advantages over conventional cables ?

XLPE cable means

cross linked polyethylene insulated aluminium conductor armoured cable. In XLPE cable

stranded aluminium conductor is first screened in the form of a semi conducting extrusion

which provides a smooth conductor surface and prevents formation of cavities at the

surface of the conductor when the cable is subjected to bending. The screened conductor

is insulated with extruded XLPE compound. The insulation is further screened with layer

of nonmetallic semiconducting material and over that a non magnetic metallic screen in

the form of copper or aluminium tape is applied. In case of multicore cables cores are

laid together with suitable filler in the interstices and wrapped with PVC tapes or

extruded PVC. For mechanical protection non magnetic aluminium wire/ strip/tape armour

for single core cables and steel wire armour for multicore cables are provided over the

inner sheath. A layer of PVC/PE is extruded as outer sheath usually in back colour to

prevent ingress of moisture.

The space feature of the XLPE insulation is that long molecular chains of polyethylene

are cross linked to each other by means of a process similar to vulcanisation of rubber

and thus forming a three dimensional network structure with strong bond. Pure

polyethylene is a thermoplastic material i.e. it becomes soft and plastic on heating and

hard on cooling. Pure polyethylene is converted into thermosetting XLPE i.e. it sets

permanently when heated. By cross linking process the polyethylene insulation of the

cable is made thermally stable and also the melting point is greatly increased. So XLPE

insulated cable has better resistivity to thermal deformation for its higher thermal

tolerance property. Due to excellent thermal properties the current carrying capacity of

XLPE cable is higher than that of conventional cable. XLPE insulation has higher

dielectric strength compared to other conventional dielectrics used for cables resulting

low dielectric loss.

XLPE cable is made suitable for high voltage and extra high voltage application puto 132

kV. This cable can be used for long cable routes in high voltage transmission where the

dielectric losses play a major role. This cable can easily be hadled due to lighter in

weight than any other high voltage cable. As there is no case of oil migration from

insulation it can be installed for inclined or vertical runs without any hesitation. XLPE

insulation is highly resistant to moisture for which no special precaution is needed at

the time of jointing & termination. The joining of XLPE cable needs less time than that

of any other conventional cable of similar grade. These cables can safely be used on any

vibrating layouts like bridges. These cable have the better resistance to salinity of

water in the ground, chemicals, oils and corrosive furnes. These are free from fire risk.

These cables are not prone to failure due to ageing characteristics and have longer life.

Advantages of Using ABC Cables:

narrow gaps of buildings. It is totally not possible to install bare conductors

there.They are also quite ideal for places such as hilly areas or dense forest.ABC Cable

Company ensures that they lay power lines there without trimming any trees.

Common Types of Electrical Wire Used in the Home

Knowing the basic wire types is essential to almost any electrical project around the

house. When you're installing new wiring, for example, choosing the right wire or

cable is half the battle. And when you’re examining existing wiring in your home,

identifying the wire type can tell you a lot about the circuit the wiring belongs to—for

example, when you open a junction box and need to determine which wires go where. Wiring

for modern homes is quite standard, and most homes built after the mid-1960s have similar

types of wiring. Any new electrical installation requires new wiring that conforms to

local building codes.

Here are some common types of home electrical wire.

It helps to understand a few basic terms used to describe wiring. An

electric wire is a type of -

conductor, which is a material that conducts electricity. In the case of household

wiring, the conductor itself is usually copper or aluminum (or copper-sheathed aluminum)

and is either a solid metal conductor or stranded wire. Most wires in a home are

insulated, meaning they are wrapped in a nonconductive plastic coating. One notable

exception is ground wires, which are typically solid copper and are either insulated with

green sheathing or uninsulated (bare).

The most common type of wiring in modern homes is in the form of nonmetallic (NM)

cable, which consists of two or more individual wires wrapped inside a protective plastic

sheathing. NM cable usually contains one or more “hot” (current-carrying) wires, a

neutral wire, and a ground wire.

As an alternative to NM cable, individual wires can be installed inside of a rigid or

flexible metal or plastic tubing called conduit. Conduit is typically used where the

wiring will be exposed and not hidden inside walls, floors, or ceilings.

These larger wires in your home are carrying circuit voltage, and they can be very

dangerous to touch. There are also several wires in your home that carry much lesser

amounts of "low-voltage" current. These are less dangerous, and with some, the

voltage carried is so low that there is virtually no chance of shock. However, until you

know exactly what kind of wires you are dealing with, it's best to treat them all as
