NEMA 6-20P to IEC320 C19 - 20A - 15 Feet

As our dependence on technology increases by leaps and bounds, the demand for their accessories also keeps increasing. For instance we cannot imagine life without a cell phone which has become a necessity in the same way as water (well, to a certain extent). A few years ago these electronic devices were our want but now it has taken the shape of a need. Spending a day without the cell phone is like a day without breath or like without single drop of water. Nevertheless an electronic device is never complete without its accessories. The accessories of the electronic gadgets are as important as the gadget itself for the proper functioning of the electronic devices. One such important electronic accessory is the power cords that relay the signal from one place to the other.

In this age of instant gratification where life is all about technology we are so much enamored by the electronic gadgets that we find it difficult to get separated from them. It is virtually impossible to avoid being the clave of technology. Every day we awake to new innovations of technology that takes us by storm and we become glued like never before to our electronic devices. To stay in pace with the innovations of electronic gadgets, the accessories are designed in a way to complement with the sophistication involved in the gadgets. Power Cords are one such electronic accessory that is an extension of the gadget itself.

A power cord has the feature of connecting an appliance with a socket on the wall. The terms are generally used for cables using a power plug to connect to a single-phase alternating current power source at the local line voltage. Power cords come in normal and high-temperature variants, as well as various rated currents. The connectors have slightly different shapes to ensure that it is not possible to substitute a cable with a lower temperature or current rating, but that it is possible to use an over-rated cable. Cords also have different types of exterior jackets available to accommodate environmental variables such as moisture, temperature, oils, sunlight, flexibility, and heavy wear.

We could have used wireless mode of transfer of signals but there is loss of data by this method while a power cord helps in full data transfer and there is minimal loss. It is generally made of a material that is long lasting and even stronger than copper and more able to retain its transmission properties after physical stress such as weight strain, or even attack by rats and cockatoos. The fiber that is installed in a power cord is different from copper: in good quality coatings, inside ducts, or in the case of newer systems, encased entirely by electrical transmission wires.

As the world of technology endeavors to bring new innovations to the forefront, the demand for electronic accessories would also rise.

If we look at the features of an optical cable it is a cable containing many cables. The optical fiber elements are coated with plastic layers and contained in a protective tube suitable for the environment where the cable will be deployed. It is used to transmit signals at very fast speed. It is usually made of glass that is long lasting and even stronger than copper and more able to retain its transmission properties after physical stress such as weight strain, or even attack by insects. The fiber that is installed in optical cable is different from copper: in good quality coatings, inside ducts, or in the case of newer systems, encased entirely by electrical transmission wires.

Contrary to an optical cable used in relaying a data a wireless mode of data transfer can be used but the reason behind that we prefer to use an optical cable is that there is no loss of data and much more data can be encoded and sent via an optical cable That’s not to say that wireless solutions are poor, rather they have a place that complements the offerings of fiber optical systems.

A form of optical cable is HDMI (High-Definition Multimedia Interface) that is a compact audio/video interface for transmitting uncompressed digital data. Coming in a variety of different types they are meant to bring sophistication to the world of technology like radio frequency (RF), coaxial cable, composite video, S-Video, SCART, component video, D-Terminal, and VGA. Technical development blesses us with pleasurable surprises that bring comfort to our lives.

The other terms used for these power cables are flex lead, main lead or kettle lead etc. Usually power cords have one end permanently joined the appliances and the other to be joined into the power plug. These days most of our home appliances come with more safer and different type of cables called cord sets. These cord sets which prevails the whole market at present and have the same use as that of power cables but provides the equipment and appliances with extra safety and shock proof features.

The cord sets like the power cables are made of flexible cord but have male and female connectors. One end of the cord set is attached to a molded electrical plug and the other is typically a molded electrical receptacle to prevent the possibility of having an exposed live prong or pin which would cause electric shock. The female plug is connected to the piece of equipment or appliance while the male plug connects to the electrical receptacle or outlet. A cord set sometimes includes accessories such as fuses for over current protection. Power cords for sensitive instruments usually include a shield over the power conductors to minimize electromagnetic interference.

Power cables come in normal and high-temperature variants for various rated currents. The connectors usually have slightly different shapes to ensure that it is not possible to substitute a cable with a lower temperature or current rating. These cords have different types of exterior jackets available to accommodate environmental variables such as moisture, temperature, oils, sunlight, flexibility and heavy wear. For example, a heating appliance may come with a cord designed to withstand accidental contact with heated surfaces.

There are international standard designs and shape assigned for power cables for particular appliances and equipment based on the current ratings of them which gives the user more choices across the brands. But there are many manufacturers which do have their unique designs and shapes to insure the products safety but these are mostly very costly which led to the emergence of small manufacturers who make good quality cords supplies across the brands and charge comparatively lesser amount. The different cables include your destop/laptop power cables, mobile charger cables and other daily use appliances cables. One must be careful about the choice of power cords as similar looking cords may have different current ratings and may not be good to use in certain appliances which have different ratings.
