An electric cable has the purpose of transporting electrical

energy from one point to another. Depending on their final

application, House Wiring Cables can have different

configurations, always basing their design on national and

international regulations.

Types of the 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


Power cables

VDE Approved Cable
s for industrial facilities and public

places. It is common to find power cables 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 cables is very varied. We can

find Rubber

s 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


Control cables

Welding Cable
s 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


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 Silicon Rubber 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

s, one of the most indispensable tools we use today,

but too often with little consideration. And, sometimes used in

a fashion that could have disastrous results.

In 1997, more than 12,000 people were treated for electrical

shocks and burns; about 2,500 of them were treated for injuries

stemming from extension cords.1 In addition, each year about

4,000 injuries associated with electric extension cords are

treated in hospital emergency rooms. Half of these injuries

involve fractures, lacerations, contusions, or sprains from

people tripping over extension cords. Roughly 3,300 home fires

originate in extension cords each year, killing 50 people and

injuring about 270 more.2 However, with a little care and some

precautions, these conveyors of power can be used safely.

We must caution up front, that if you have more than a few

Heater Cord

s powering equipment in your lab, it is probably time to

either call an electrician to install additional strategically

placed outlets, or to rearrange equipment. Likewise, if you have

any cords running through walls, up through the ceiling and down

somewhere else, an electrician is definitely required. Extension

cords should only be used when necessary and only for temporary

use. You should always plug equipment directly into a permanent

outlet when possible. Where this is not possible, however, you

should begin by selecting the right cord for the job.

Indoors or outdoors, the use of cords serve different needs

and should be selected accordingly. Regardless of location,

always use the three-prong type of cord approved for either

indoor or outdoor use. In addition, the cord should have a

certification label from an independent testing lab such as

UL Rubber

or ETL (Electrical Testing Laboratories) on the

package and attached to the cord near the plug.

The amount of current a

Power Cord

can handle will depend on the diameter of the conductors (copper

wire part of the cord). Cords that contain more copper can

safely handle more power. The wire size is measured by the gauge

of the wire. You will usually find numbers like 16, 14, or 12

gauge on an extension cord package and the cord itself. Now,

this is one of those confusing issues. You would think that a

16-gauge wire is bigger than a 12-gauge wire, but it’s not! As

the number gets smaller, the thickness of the conductor gets

bigger. A 12-gauge wire can safely carry much more power than a

16-gauge wire. Compare the capacity on the label to the intended


Always use the shortest


possible, to minimize risk of damage to the cord and

reduce electrical resistance across the length of the cord.

Extension cords, by the nature of their length and conditions of

use, are much more prone to damage than other types of wiring.

It is important to check the total length of the cord for damage

before putting it into use.

One should start by looking at the ends of the cords. The

male end—the end with the three prongs that fit into an

electrical outlet—is the one that is most prone to damage. The

two flat power-conducting prongs are subject to bending, while

the round prong (often called the ground pin), can be broken

off. Without the ground pin there is no path to ground through

the wires—potentially a very dangerous situation.
