1. Aluminum is lighter and cheaper than copper, though it has lower conductivity.
2. PVC wire is durable against water, heat, oil and UV light and widely used with long life.
3. 'Bad' conductors are used to convert electrical energy into heat, light and sound in devices.
4. Exceeding a cable's current carrying capacity can cause overheating, damage insulation, and result in short circuits.

Modern underground power cables are sophisticated assemblies of insulators, conductors and protective materials. Within these components are sensors, which enable cable operators to monitor conditions along the cable in real time.
The condition of the cable insulation is usually monitored through the following two main methods:
Loss tangent measurements
Partial discharge (PD) measurements
This is the simple ppt explaining about the main components of the power systems. especially we are determining the insulators and its types with real time pictures which are attractive,
Construction of cables
Parts of a cable
Properties of cable insulators
Properties of conductors
Types of cables
Underground cables
Methods of laying underground cables
Types of cable faults
Comparison between overhead and underground cables
Since the loads having the trends towards growing density. This requires the better appearance, rugged construction, greater service reliability and increased safety. An underground cable essentially consists of one or more conductors covered with suitable insulation and surrounded by a protecting cover. The interference from external disturbances like storms, lightening, ice, trees etc. should be reduced to achieve trouble free service. The cables may be buried directly in the ground, or may be installed in ducts buried in the ground.

Why copper wires are used extensively?Ganpati Wires
copper wires are available almost everywhere on local electrical stores; Copper Winding Cables are good for transferring the current. When a high voltage of current passes through a wire, the surface temperature of it is expected to increases.

The design of electrical machines and equipments mainly depends on the quality of these materials. Low grade materials result in bulky and costly equipment generally

https://bit.ly/BabeSideDoll4u Babeside is a company that specializes in creating handcrafted reborn dolls. These dolls are designed to be incredibly lifelike, with realistic skin tones and hair, and they have become increasingly popular among collectors and those who use them for therapeutic purposes. At Babeside, we believe that our reborn dolls can provide comfort and healing to anyone who needs it.
The Healing Power of Babeside's Handcrafted Creations
Our reborn dolls are more than just beautiful pieces of art - they can also help alleviate stress, anxiety, depression, and other mental health conditions. Studies have shown that holding or cuddling a soft object like a stuffed animal or a reborn doll can release oxytocin, which is often referred to as the "love hormone." This hormone helps us feel calm and relaxed, reducing feelings of stress and anxiety.
In addition to their physical benefits, reborn dolls can also offer emotional support. For many people, having something to care for and nurture can bring a sense of purpose and fulfillment. Reborn dolls can also serve as a reminder of happy memories or loved ones who have passed away.
Welcome to the Program Your Destiny course. In this course, we will be learning the technology of personal transformation, neuroassociative conditioning (NAC) as pioneered by Tony Robbins. NAC is used to deprogram negative neuroassociations that are causing approach avoidance and instead reprogram yourself with positive neuroassociations that lead to being approach automatic. In doing so, you change your destiny, moving towards unlocking the hypersocial self within, the true self free from fear and operating from a place of personal power and love.

wiring Part 3: wires & cables
1. Wires & Cables
Energy & Environment
This PowerPoint is created and developed by :
2. Conductors
A conductor has many free electrons so is good at transferring
electrical current

6. Wires & Cables
Wires & Cables are purpose built conductors
The size & type of wire/cable must suit the power rating required for
their use. The higher the power the thicker the wire/cable

Neutral
wires do?
Live
Provides current to
appliance
Earth
Takes current to ground if
appliance has fault
What wire is missing and
why?
11. Standard Wire Gauge & Current
Carrying Capacity
Maximum safe
Each number current that can
represents a size of flow through a
wire cable
Higher current will heat
the cable and damage the
insulation and may result
in short circuit
12. Cables
Larger sized conductors
Types of cable are sorted by:
Type of insulation Type of conducting material
Cotton covered Copper
Silk coated Aluminum
Asbestos covered
Rubber coated
PVC coated
Their shape Mechanical protection Voltage Grade
Flat Unarmored Low
Round Armored High
13. Splices & Terminals
When a cable enters into an accessory its called a termination.
Splices or terminals must be used at termination points
These must be as mechanically & electrically strong as the conductor or
device which it is used.
Types
Pillar terminals
Screw heads & nuts
Washers
14. Summary Questions
1. Why might you use aluminum in wire instead of
copper?
2. What are some advantages of PVC wire?
3. Why might you use ‘bad’ conductors in a circuit?
4. Why is it important not to supply a cable with
more current than its current carrying capacity?
