Chapter One:Understanding Power Cbales
What is the power cable?
Another name for power cable is the portable cord. Power cables are cables with two electrical conductors that aid the transmission of electrical power. They usually connect to a wall socket or extension cord to transmit electricity.
How does it work?
They serve different purposes and are compatible with several varying construction and materials. Power cables are suitable in electric utility, industrial and commercial market. These cables work for miming, lighting, welding applications and so much more.
These cable types are fit for temporary power supply rather than a permanent basis. Although some power cables function as a permanent means of electrical supply in buildings. In supplying electricity to motors and appliances, power cable becomes a service cord.
Jacket material types: PVC jacket and rubber jacket
Both jacket material types are power cable insulation materials. The PVC jacket is a low voltage insulation material. PVC means Polyvinyl chloride. It is easy to maintain and is oil resistant. PVC jackets also resist the effect of other chemicals. Sadly, when the PVC jacket burns, it induces harmful gases into the air. These gases, such as dense smoke and hydrogen chloride gas, are detrimental to human health. The PVC jacket is prone to lose its insulating properties if it is made open to sunlight.

The rubber jacket is an organic insulation material. Just like the PVC jacket, it is also oil resistant. This material makes power cables very flexible. However, as it ages, it becomes hard and brittle. But, as soon as the rubber cracks, it loses its insulating properties. Another interesting feature of the rubber jacket is that it is resistant to ultraviolet radiation and ozone presence. All these qualities are dependent on the formation of the rubber jacket. It is also suitable for heavy duty applications.
Features of the power cable
Power cables possess a female conductor that connects to any appliance in the case of detachable leads. It helps to avert the dangers of having a live protruding pin. As it is a great threat to life.
It possesses a retaining clamp that protects it from cases of rough handling the power cable. They make it easier for equipment to function by the safety requirement. As such, electrical currents reach distant places.
Furthermore, these cables possess cords. These cords are fuses, pilot lamp, and a current detector. The cords are a shield to curb the effect of electromagnetic interference. More so, these cords help to prevent wrongful disconnection on any side of the cable.
Therefore, power cables possess suitable features that make the environment hazard-free as long as the connection is built correctly to the right channel.
Chapter Two:Power Cable Types
AC power cable
What is AC power cable?
AC power cable means alternating cable. This power cable type aids connection to electrical equipment at buildings and various places. It comes in various voltage, current rating, shape, and size. AC power cable consists of the main plug which connects to a flexible cord.
How does it work?
In order to work effectively, the power ON/OFF must be in the right setting. More so, the cord of AC power cable is to connect to any appliance whatsoever that needs electricity to work. It facilitates the trade of electrical appliances. Though, in some cases, the AC power cable is also part of an electrical appliance. That is, it stays with the appliance on a permanent connection.
Additionally, it works well for the comfort of consumers and the benefit of people who import electrical goods. It also suits building wiring. This power cable is relatively safe and helps in electrical noise reduction.
Also, it reduces the generation of heat, and with the AC power cable, replacement is quite easy.
DC power cable
What is the DC power cable?
DC power cable is an acronym for the direct current power cable. It allows electric charge flow in one direction. It flows easily through a conductor, semiconductors or insulators. An example of a DC power cable is a battery.
How does it work?
It allows conversion into an alternating current such as an inverter. It aids the production of aluminum and electrochemical processes. Additionally, in making railways in urban areas, this power cable type is very useful.
It helps in changing batteries of electronic systems and motors to large power supplies.
Transmitting a large amount of power from a remote environment to an alternating power grid is possible with the DC power cable.
Automotive applications, telecommunications, and high voltage power transmission use DC power cable.
Summarily, both the AC power cables and DC power cables help transmission of information. But, they transmit electricity using different voltages.
Chapter Three:Power Cable Connector Types-International Standard IEC60320
What is IEC 60320?
IEC means International Electrotechnical Commission. It is a set of standard that specifies nonlocking appliances which connect power cables to electrical appliances within the range of 250 voltages. IEC 60320 is a standard that a lot of countries favor. The ‘C’ in IEC 60320 signifies the code standard of the connectors of IEC 60320.
The C1/C2 coupler is a connector and appliance inlet that is compatible with electrical appliances.

This coupler suits cassette recorders, battery radio, battery charger, laptop computer power supply, full-size audiovisual equipment, and some other appliances.
It makes use of a power cable with a suitable power plug which connects to one end of the appliance and the other end to the C13 coupler.
They are suitable for computers, routers, servers, and even switches. More so, the C13/C14 couplers assist in providing power from a power distribution unit to a server.
They share similar characteristics with the C13/C14 coupler except for slight differences. A unique difference between the C13/C14 coupler and the C15/C16 coupler is the temperature rating.
C15/C16 couplers are very compatible with hot household appliances such as kettles.
These couplers are similar to the C15/C16 couplers except that they possess higher temperature ratings. The temperature rating of C15A/C16A is 155°C.
They are suitable for very hot household appliances.
This coupler is very similar to C13/C14 coupler, but they are unearthed.
It is a fit for IBM Wheelwriter series of the electronic typewriter, audio applications, power supply of Xbox 360 game consoles and large CRT televisions of the 1990s.
It is rectangular and earthed. Its pins are parallel to the long axis of coupler face.
The C19/C20 couplers are suitable for IT applications that make use of high currents such as high power workstations and servers, uninterrupted power supplies, large network routers, PDU, switches, blade enclosures, and other equipment.
It is a coupler type that makes use of a high IEC heat rating. It is not a very common type of coupler, but there are high future expectations of it. A lot of power systems find this coupler very useful. In situations of very high temperature, C21/C22 coupler handle the heat ratings effectively.
These couplers work well for high current equipment such as data or blade servers.
It is an ungrounded variant of C19/C20, and they have two conductors.
This coupler does not work well in high-temperature ratings like the C23/C24 couplers. They operate on a maximum of 70°c.
It is important to use couplers for productivity purposes. However, the wrong choice of couplers is enough to mar the much-expected result in production.
