Wire
A wire is a thin, pliable, and elongated conductor composed of a conductive
substance, usually metal, employed for transferring electrical signals or conducting electric
current. Wires play a crucial role in electrical and electronic systems by facilitating the
movement of electric charge. An individual metallic conductor is usually cylindrical.
Earth, Live, and Neutral wires are the three types of wires commonly encountered in residential
circuits. The earth wire is a precautionary measure, specifically for devices with metallic
enclosures. The wire was coated with green insulation.
Construction of PVC Wires
Conductors
PVC wires commonly use copper conductors, while aluminium conductors
are utilized in some applications. Copper conductors are highly conductive and are the
chosen choice for many electrical wiring applications.
Insulation
The conductors are coated with PVC (Polyvinyl Chloride) for electrical
insulation and protection from moisture, chemicals, and environmental elements. PVC
insulation is robust, pliable, and resistant to abrasion, making it appropriate for indoor and
outdoor use.
Colour Coding
PVC wires may feature color-coded insulation to distinguish between
various conductors and aid in correct installation and upkeep. Typical designations are red
for live cables, black for neutral wires, and green or green/yellow for grounding wires.
Size and Gauge
PVC wires are offered in various sizes and gauges, from thin gauges for
low-voltage applications to thicker gauges for larger currents and power ratings.
Sheathing (Optional)
Some PVC wires may feature an extra outer sheath or jacket
composed of PVC or other appropriate materials to provide increased protection and
insulation. The outer layer protects against physical harm, UV radiation, and moisture
penetration.
Characteristics of PVC Wires
Electrical Insulation
PVC insulation offers superior electrical insulation, limiting current
leakage and assuring electrical circuits’ safe and dependable functioning.
Flexibility
Flexibility: PVC wires are pliable and convenient for installation in confined areas and
around corners due to their flexibility. PVC insulation’s flexibility decreases the likelihood
of conductor breakage and makes cable routing easier.
Durability
Durability: PVC wires are robust and resistant to wear, tear, and abrasion damage. They
can endure mechanical stress, bending, and twisting without affecting their electrical
performance.
Chemical Resistance
Chemical Resistance: PVC insulation is chemically robust, making PVC wires ideal for
industrial settings with frequent exposure to severe chemicals.
Temperature Rating
Temperature Rating: PVC wires have a moderate temperature rating, usually between
15°C to 70°C or greater, according to the unique PVC composition and application needs.
Applications of PVC Wires:

washing machines, air conditioners, and kitchen appliances for internal wiring and
connections.
Automotive Wiring
Automotive Wiring: PVC wires are utilized in automobile wiring harnesses and electrical
systems to supply electricity to car components such as lights, sensors, ignition systems,
and entertainment systems.
Telecommunications
Telecommunications: PVC wires are used in telecommunications cables, such as
telephone and data cables, to convey signals and data between devices.
Electronics
PVC wires connect components and traces in electronic circuits, PCBs, and
electronic devices. They offer a dependable electrical connection and insulation in
electronic applications.
Advantages of PVC Copper Wire:
- Durable – Resistant to wear, moisture, chemicals, and abrasion.
- Flexible – Easy to install and bend around corners.
- Cost-effective – Cheaper compared to some other wire insulation materials.
- Flame-retardant – Does not catch fire easily.
- Good Insulation – Reduces the risk of electric shock.
Disadvantages of PVC Wire:
- Not eco-friendly – PVC is plastic-based and takes a long time to decompose.
- Toxic fumes – When burned, PVC releases harmful gases like dioxins.
- Not suitable for high temperatures – It can melt or degrade with extreme heat.
- Brittle over time – May crack or become stiff with age.
Relation to Natural and Human Rights:
Natural Rights Impact:
Environmental Concern: Manufacturing and disposal of PVC can harm the environment (air, soil, and water), violating the right of nature to remain clean and undisturbed.
Sustainability Issues: Overuse of non-biodegradable materials like PVC can affect future generations’ access to natural resources, which connects to the right to a healthy environment.
Human Rights Impact:
Right to Health: Burning PVC wire (especially in informal or unsafe settings) can expose workers and residents to toxic fumes, affecting their right to health.
Right to Safe Working Conditions: Workers handling PVC wires should be protected with proper equipment and conditions, respecting their right to safety and well-being.
Right to Clean Environment: Improper disposal of PVC wires can pollute communities, infringing on people’s rights to live in a safe and clean environment.
Cable
A cable is a collection of one or more conductors, usually isolated from each other
and sometimes collectively insulated or shielded, which is utilized for transferring electrical
signals or power. Cables are more intricate than individual wires, which frequently incorporate
numerous conductors, shielding, and insulation materials. Cables have multiple functions in
electrical and electronic systems, serving as a medium for carrying power, data, or signals
across short and long distances. Below are a few fundamental characteristics of cables:
Components of a Cable
Conductors
The conductors within a cable refer to the individual wires or strands responsible for
transporting electric current. Typically, these conductors are composed of metals such as
copper or aluminum.
Insulation:
Each conductor is provided with insulation to prevent the occurrence of short circuits and
accidental contact with other conductors or surfaces. The insulation materials comprise
PVC, XLPE, rubber, or non-conductive materials.
Shielding:
Some cables are shielded to protect signals or power transfer from external interference or
avoid signal leakage. Typical materials used for shielding are metallic foils or braiding.
Sheath or Jacket
The outer layer of the cable, known as the sheath or jacket, offers general protection and
insulation for the complete cable assembly. It protects the internal components against
external elements such as dampness, chemicals, and physical harm
