Advantages And Disadvantages Of Pvc

Insulate - to cover, line, or separate with a material that prevents or reduces the passage, transfer, or leakage of heat, electricity, or sound (Insulate ,2015, pg.1). In this experiment insulation is the main topic. Insulation is used in many things: a house, a refrigerator, walls, clothing, and types of drinking cups. Installation can be made of materials like styrofoam, plastic, and fiberglass. These can be used to keep things hot or cold. Insulation is most commonly for heat and maintaining heat energy. This experiment tests the insulation of several cups and how they keep liquids hot. Each cup used in the experiment has some insulation. The cups have different amounts of insulation. Each of these cups are generally used as insulators for many liquids.

The whole thing is usually wrapped in another layer of insulation and, finally, in an outer protective layer. (/coaxial_cable.html)

Insulator – Do not allow electric charges to pass through them. Electrons in the atoms and molecules move very slightly to one side of the object but are not released.

Non Conductive: A serious concern with outdoor cables in certain computer networks is they can be hit by lightning, causing destruction to wires and other cables that are involved in the network. Fiber optic cables can be made non-conductive by avoiding metal in their design. These kinds of cables are economical and standard for many indoor applications. Outdoor versions are more expensive since they require the special strength members, but they can still be valuable in eliminating ground loop and protecting electromagnetic equipment from surge damage.

Data Link Layer encrytion encrypts all the data along a specific communication path, as in a satellite link, T3 line, or telephone circuit. Not only is the user information encrypted, but the

Coaxial cable uses a single conductor in the middle of a cable and the central conductor is surrounded by an insulator which is called the dielectric. Coax cables have become obsolete. Unshielded twisted pair cabling, also known as UTP cabling, has become the most common used network cabling. UTP cabling consists of four twisted pairs of wire, which have a different number of twists per foot, all encased on one sheath. This cabling is graded by different categories. Category 5 is recommended for Ethernet speeds of 100 Mbps. Category 5e, for running gigabit Ethernet or 1000BaseT networks. Category 6 and Category 6a are used to give better performance at higher speeds. Fiber optic cable is wave guided or light guided because it guides the light waves along the length of the cable. Single mode fiber optic cable can operate over long distances. Because fiber allows one mode of light to propagate, light pulses put on the fiber keep their shape much longer. This allows the light pulses to travel much further without interfering with other

10. Fish Tape : a flat tempered spring-steel tape or wire used in pulling electric wire and cables (as into conduit runs) —called also snake wire

- a layer off fatty tissue such as like a home electrical wire that speeds their impulses.

3. Coaxial: A single copper wire surrounded by insultation. More expensive than copper twisted pair

It never fails to amaze me what end users will admit to when you ask the right questions. If you ask a user in a nonthreatening manner about any physical stress that the cable might have endured, they’ll usually tell you. Remember that most users have no idea that a fiber cable can be destroyed if stepped on or bent too sharply, or if they roll a chair over it.

2.What are the following cable types used for and how are they made? How are they different?

Jacobs sells its chemical to manufacturers of air conditioner retrofit kits. The manufacturers are all located in the region of Calopeia. They purchase the foam chemical as a substitute for competitors' products. If Jacobs cannot ship an order within 24 hours of receiving the order from the customer, the customer makes its purchase from a competitor without any loss of future demand.

When tested in the lab, it was found that Advance Wire was mediocre in conductivity & abrasiveness, while also being heavier than all other samples.

Now we will move onto other materials that are involved with electronics. The next group of materials that will be discussed are insulators. An insulator is a material that does not conduct electricity at all but will resist or stop it from traveling further. An insulating atom has eight electrons in its valance shell which makes this shell complete. Eight is the most electrons that any atoms can have in their valance shell this is why these are called insulators, no more electrons can fit in the valance shell of these atoms.
