Electrical Cable: What Is It?
The cable utilized for the transmission and distribution of electrical power is referred to as an "electrical power cable."It is used to transmit high voltages in locations were using overhead wires is impracticable.
Electric cables are made up of:
A power cable is made up of three fundamental components: a conductor, a dielectric, and a sheath. The conductor creates a path for the current in the cable to follow. The insulation or dielectric protects the live conductor from outside elements and can withstand the service voltage. The sheath shields the cables from all outside impacts, including fire and chemical or electrochemical assaults, and prevents moisture from entering.
Electrical cables Voltage
Because electrical wires are measured in volts, they can be divided into the following:
Low voltage cables (up to 750 V).
Available with both thermoplastic and thermoset coatings in a wide range of applications. They were created and constructed in compliance with standards that are acknowledged worldwide.
cables with low voltage (up to 1,000 volts): (alternatively written 0,6/1 kV) The cables in this section are utilized in a variety of industrial power installations (general industry, public installations, infrastructures, etc.). They were constructed in conformity with world standards (UNE, IEC, BS, UL).
Medium voltage cables range from 1 kV to 36 kV.
They carry power between transformer stations and substations.
The voltage of high-voltage cables begins at 36 kV.
They are used to move electricity from one place to another.
What Do Electrical Cable Colors Mean?
Many wires with various functions can be found in an electrical installation. For the insulators to perform effectively, specific colors have been established to denote their purpose better.
The electrical cable insulation comes in the following colors:
Green and yellow wire: The ground connection is formed with the help of the ground wire.
Blue wire: The neutral wire is it. Remember that the neutral wire was red until 1970 if you have an older installation.
Brown wire: The phrase is used with this wire. Additionally, the phase wire might be gray or black.
Black wire: Phase wire can also be black.
White wire: This neutral wire connects to the transformer.
Colored cables: Any colored cable without a striped outside is a current-carrying cable.
Striped colored cables: Similar to white wires, striped cables are neutral. They are used to distinguish the neutral wire from other colored wires and to connect them.
Cables: types and features
Cables are divided into 5 categories depending on their use as follows:
Ribbon Electric Cables
It is constructed of several insulated wires that run parallel to one another and is used to transfer multiple pieces of data at once. This, for instance, connects the CPU to the motherboard and is typically used to connect networking devices.
Shielded Cables
It comprises 1 or 2 insulated wires that are shielded by a woven braided shield or aluminum Mylar foil for improved signal transmission and to eliminate radio interference from the outside world and frequency irregularities. These cables are shielded and used to transfer high-voltage electric current.
Twisted Pair Cables
It consists of two or more colored, insulated copper wires that are twisted together. These wires are typically found in telephone cables, and the number of wires used can be used to measure how resistant they are to outside interference.
Coaxial cables
This consists of a solid copper or steel conductor that has been copper-plated and is wrapped in metallic tape and braid. This has an insulated protective outer jacket covering it completely. Both computer networking and audio-video networking employ these types of wire.
Fibre Optics Cable
These cables are used to transmit optical data signals from an attached light source to the receiver.
