what do insulating means?
449536
insulate\nverb insulated, insulating\n\n1. To surround (a body, device or space) with a material that prevents or slows down the flow of heat, electricity or sound.\n2. To remove or set someone or something apart; to isolate.\n\nThesaurus: shield, cushion, sequester, protect, isolate, cut off, cocoon, quarantine.\nEtymology: 16c: from Latin insula island.

I think the reason for the insulator layer is obvious. The conductor layer is probably to shield against emission of electromagnetic energy which can interfere with communications (such as radio and TV reception) and other electronic equipment, and may also be a safety measure to produce a high fault current to trip a breaker in the event of cable damage.

HVAC may also stand for High-voltage alternating current\n\nHVAC (pronounced either "H-V-A-C" or, occasionally, "H-VAK") is an initialism/acronym that stands for "heating, ventilation and air-conditioning". This is sometimes referred to as climate control.\n\nThese three functions are closely interrelated, as they control the temperature and humidity of the air within a building in addition to providing for smoke control, maintaining pressure relationships between spaces, and providing fresh air for occupants. In modern building designs, the design, installation and control systems of these functions are integrated into a single "HVAC" system.\n\nIn certain regions (e.g., UK), the term "Building Services" is also used and HVAC Engineers are called Building Services Engineers. See CIBSE.\n\nThe term air handler can mean a whole unit including the blower, heating and cooling elements, filter racks or chamber and dampers, but not including the ductwork through the building.

Surface static electricity is formed on insulating substances because you can by friction rub electrons onto or off of a surface.  In metals, electrons are shared between every atom in an electron 'sea' as opposed to the localised bonding in insulators.  Therefore in metals, any electrons deposited on or removed from a surface simply migrate/diffuse into the metal and remake the balance that existed initially.

Air - it is contained in the spaces of woolly and fibrous material such as clothing to keep people warm.\n\nCeramic - such as used on heat shield of spacecraft.\n\nPlastic - used on handles of saucepans.

It means, you are using their electricity.  The faster it moves the more you are consuming.  Try this link:

Brick is NOT a good insulator. Typically the insulator for a house built with brick is the air or other material trapped in the walls between the studs.

to temper something means that you are heat treating it... it is not possible to "temper" something by adding another ingredient.  (temper means heat)\n\n Annealed glass which has been heated to a temperature near its softening point and forced to cool rapidly under carefully controlled conditions is described as "heat-treated glass." The heat treating process produces highly desirable conditions of induced stress (described below) which result in additional strength, resistance to thermal stress, and impact resistance.

plastic, but it doesn't breathe, so for a person or something, wool is good.\n\nAs for insulating something that is not a person, combinations work well, and so does aluminum foil.

condensation .your warm bum + cold hard surface= condensation.

Air is a good insulator as far as it doesn't circulate. It has low conductivity (about 1,4 Btu/ft h ºF), but if you let the air circulate there can be a very good heat transmission due to convection.\nThat's why insulators try to trap small amounts of air inside, so the air stays immobile.\nVaccumm would be a much better insulator.

hey hey. finally something i know about.\n\nInsulation? by that i think you refer to the resistance on heat traveling from one area of a building to another (or from outside to inside)? well, i have heard of, fibreglass woll. spun molten rock wool, polystyrene, etc. if you are refering to building materials used by varying cultures around the world, then i would say, mud walls. clay walls, logs, stone, thatch (roofing), straw (hay), ice (igloos). If im not on the right track, im me and ill tell you other stuff

EM waves are either reflected or absorbed by electrically conductive surfaces, Insulators merely slow EM waves down but otherwise do not impede their propagation. That being said, nothing is a perfect insulator, IE. every non-conductor conducts a little bit.

"cuz I dont have material"\n\nWhat does the above mean ?

Because the stuff they use to coat the wire is (A) an insulator (B) flexible enough to bend where the wire does (C) durable to last at least 30 or 40 years (D) impervious to water (E)able to withstand the highest voltage the insulator is designed and UL listed for (F) able to withstand the temperature that the insulator is designed and UL listed to still be operable for.
