Multiple insulators are connected in series. The strain insulator is the same as a suspension insulator but it is used horizontally, whereas the suspension insulator is used vertically. The strain insulator is used to relieve the line of excessive tension, which happens when there is dead end of the line or sharp curve. Images for kids
Ms. Sneed Ponders How to Teach Conductors and Insulators. Our favorite fourth grade teacher, Ms. Sneed, and her teaching partner, Mr. Frank, were planning their electricity unit. “We’ve already worked with batteries and bulbs. And our kids can build simple circuits. Next, we’ll teach about conductors and insulators,” Ms. Sneed said.
Kids Temperature Experiment - Insulators : What is a good Insulator? ... This insulation can then prevent heat from moving into an object as well as preventing heat moving out of an object. Some examples of trapped air as an insulator are; a thermos, polystyrene cup, oven mittens, double glazed windows. ...
Insulation helps keep cold things from warming up and warm things from cooling down. Insulators do this by slowing down the loss of heat from warm things and the gaining of heat by cool things. Plastics and rubber are usually good insulators. It is for this reason that electrical wires are coated to make them more safe to handle.
Insulators are materials which do not conduct heat very well and so we can use them to control heat and keep things hot or cold. Thermos flasks are made from insulating materials. Conductors are the opposite of insulators. Heat passes quite easily through them. We can use conductors to move heat, for example, radiators are made from metal.

for Kids. Conductors and Insulators: conductors are made of materials that electricity can flow through easily and insulators are materials that electricity can not flow through easily. Good example of conductors include silver, water, people, trees, animals, aluminum ...
Insulators are the opposite of conductors. An insulator is a material that doesn't carry electricity. Insulators are important because they can protect us from electricity. Materials like rubber, plastic, and paper are good insulators. Voltage - Voltage is the name for the electric force that causes electrons to flow. It's the measure of ...
