Do you know that the beauty of an electrical installation is not based on how beautifully arranged the fittings and accessories are but on the quality of cables used?

Can that installation stand the test of time, vibrations, environmental harzards and mechanical damages? Think about it!

The outline below will boost your knowledge on the use of electrical cables and IEEE regulations to enhance your skill as an Engineer, Technologist, Technician or Craftsman.

INTRODUCTION An electrical cable is an assembly of one or more wires running side by side or bundled, which is used to carry electric current.

Electrical cables are used to connect two or more devices, enabling the transfer of electrical signals or power from one device to the other. Cables are used for a wide range of purposes, and each must be tailored for that purpose. Cables are used extensively in electronic devices for power and signal circuits. Long-distance communication takes place over undersea cables. 

Power cables are used for bulk transmission of alternating and direct current power, especially using high-voltage cable. Electrical cables are also used in building wiring for lighting, power and control circuits permanently installed in buildings. 

FEATURES OF A CABLE
Cables comprises of different parts depending on the manufacturer, rating (voltage and current ratings) 
and purpose. 
Generally, there are three main parts of a cable. These are; The conductor, insulator and the protective Jacket

(1) Conductor: This is the current carrier of the cable. It is made up of conductive materials like copper, aluminium, silver. Although, due to high cost of conductors, copper is mostly used.
(2) Insulator: This is the sheath that covers the conductor. It helps to protect the conductor against damages of any kind. It is made of non conductive materials.
(3) Protective Jacket:  This is the outer part of the cable. It is usually made of very strong resistive materials to protect the cable against damages such as mechanical, environmental and other forms of damages that would disrupt the flow of current/voltage through the cable which might lead to open or short circuit. This is mostly used for armoured and optical fibre cables.


TYPES OF  CABLE ACCORDING TO PURPOSE

There are two main types of cables under which several other cables are classified. These are;
(I) Solid cable
(II) Stranded cable

(I)  Solid Cable: This is one of the commonly used cable for electrical wiring, wiring for breadboards and other situations where wires are not required to be constantly flexed. Solid cable is built with one strand or the core of a wire that has non-conductive material for insulation. 

Furthermore, for outdoor or  heavy duty applications where cables might be exposed to corrosive particles, erratic movements and harsh weather conditions, solid cables are preferable.

Note that  if there is constant flexing or vibrations, this cable could wear down and break.

(II) Stranded Cable: This is made up of a collection of small gauge wires that are insulated and compressed with non-conductive materials. It is also used in areas where there is considerable flexing or vibrations espically in electrical/electronic appliances or equipment such as speaker wire, headphone cables and so on.

This cable have strong resistance to vibrations. They are more flexible, lasts longer and have less eddy current losses.

NIGERIAN CABLES

Over the years several Nigerian manufacturers has risen to produce quality cables that will stand the test of time and other conditions. Today, Some of these companies produces cables that meets the standard. Some of these companies are listed below;

1. C Divine Answer Ltd: C.Divine Answer International Company Limited manufactures and supplies all kinds of quality cables including armoured and non armoured cables, aluminium cables, PVC single, power, flexible and flat cables.

2. Coleman Technical Industries: This industry manufactures electrical wires and cables for all industrial, domestic and commercial uses.

3. Comet Star Manufacturing Company Ltd: This company specialises in armoured cables, conduit, surface wiring cable, earthing copper conductor cables and aluminium conductors.

4.  MicCom Cables & Wires: This is the first indigenous cable manufacturing company in Nigeria. She specializes in different kinds of telecommunication cables.

5. Vecan Cable Limited: This company manufactures high quality cables of different types and sizes.

6. Berliac Engineering Cables: This company produces high quality cables and wires for both domestic and industrial use.

7. Purechem Cables: This is an established manufacturer of high quality and reliable Copper, Aluminium Cables. This company also designs and manufactures Power Cables as per specific customers requirement.

INSTITUTE OF ELECTRICAL ELECTRONIC ENGINEERING (IEEE) REGULATIONS

Majority of installers in Nigeria pay less attention to IEEE regulations. This is the main reason for some installations failure within few years of usage. When these regulations are judiciously implemented, installations will stand the test of times. Some of these are stated in the diagram below;

Special Points:

1. Quality Cables are not known by the beauty of the insulating jacket or packaging materials but by the material the cores are made of.

2.The current and voltage required to be passed from one point to another in a circuit is the determinant for the actual size and type of cable to be used

3. Go for quality cables to avoid catastrophic failure in an installation.

4. For commercial and industrial installations where vibrations are constant, stranded cables are preferable.

So then, getting quality cables at affordable prices could be quite difficult, but PREIGHT is available at all times to supply durable, quality, reliable cables of different types and sizes to your doorstep.

Wow, isn't that so  Amazing?
