Topic 2 Electrical Conductors and Insulators Insulators and Reinforcing Conductors Natural Sciences and Technology - Grade 6

Important facts about insulators Materials that do not allow electricity to pass through them, are called electrical insulators. A few examples are rubber, plastic, wood, ceramic and glass. An electrician must wear rubber gloves to protect himself/herself from shocking. wear gloves Natural Sciences and Technology - Grade 6

Natural Sciences and Technology - Grade 6 Electricity pylons Natural Sciences and Technology - Grade 6

Natural Sciences and Technology - Grade 6 Electricity pylons Electricity does not flow down the pylon, because the pylons have ceramic or glass insulators to support the overhead power lines. If electricity flowed down the pylon, people or animals touching the pylons would be electrocuted. The ceramic colourful caps that hold the wires of power and telephone lines are good insulators, because it does not conduct electricity. Natural Sciences and Technology - Grade 6

Natural Sciences and Technology - Grade 6 Electrical cords The plastic covering the electrical cords is an insulator that prevents people from getting shocked. Natural Sciences and Technology - Grade 6

Natural Sciences and Technology - Grade 6 Types of insulators Glass insulators It insulates the electrical wires they carry, so that electricity (or telephone calls) do not all leak into the pole and into the earth. It would be impossible to transmit electricity to homes and businesses without insulators. Natural Sciences and Technology - Grade 6

Natural Sciences and Technology - Grade 6 Types of insulators Smaller glass insulators are used on the circuits of telephones and telegraphs. Larger glass insulators are used for electrical (power supply) wires. Natural Sciences and Technology - Grade 6

Natural Sciences and Technology - Grade 6 Types of insulators 2. Heat insulators Natural Sciences and Technology - Grade 6

Natural Sciences and Technology - Grade 6 Types of insulators (Heat insulators) If you put clothes on, it warms the body and keeps the heat in. Insulating a house is actually a very good idea, because the more heat insulation you have: the less energy escapes; the lower your fuel bills; you help the planet in the fight against global warming. Natural Sciences and Technology - Grade 6

Natural Sciences and Technology - Grade 6 Types of insulators (Thermal insulators) Wall insulation of a wooden structure. Natural Sciences and Technology - Grade 6

Natural Sciences and Technology - Grade 6 Types of insulators (Thermal insulators) It keeps warm air inside your home. Thermal insulation in the ceiling and wall structures of a building have the following advantages: - It prevents cold or hot air escaping from the interior room to the outside. - Less heat enters or escapes which is efficient for cooling and heating systems. - Heat from exterior building walls, which capture the sun’s heat energy, cannot be transmitted.
