Log in, Concise Mathematics Class 10 ICSE Solutions 2018. For example, air can function as an insulator if it occurs at room temperature, if it undergoes certain changes in its temperature, it can act as a conductive agent. But, as with all insulators, they have a breakdown point where a high enough voltage across them will allow current to be conducted. Choose the correct answer: The synthetic plastic used for making insulation cover in electrical wires and cables is . Today, Bakelite is manufactured under various commercial brand names such as Micarta. Insulator definition: An insulator is a material that insulates something. ESD Bakelite sheet provides a uniform anti-static value. Substrate is phenolic resin and electric grade bleached wood pulp paper . Question 3. For example, using hexamethylenetetramine as the curing agent, the curing temperature is 150 ℃, and the molding powder mixed with filler is commonly known as bakelite powder. Sponsored by Bloomberg News. Large number of thermoplastics are used everywhere due to their ease in use and moulding. Blanket is one example of a good insulator that keeps you warm. Bakelite Phenolic sheet is a hard, dense material made by applying heat and pressure to layers of paper or glass cloth impregnated with synthetic resin. Bakelite, melamine, urea, available in powder form, are extremely mouldable thermoset insulation materials. gadho072 gadho072 Answer: i am so thankful to answer your question. Give few examples. The lower part of the insulator is located within the transformer body and therefore can be made smaller than the upper part located in open air. Please enable Cookies and reload the page.

Bakelite stock is still manufactured and produced in sheet, rod and tube form for industrial applications in the electronics, power generation and aerospace industries, and under a variety of commercial brand names. A) cellulose B) starch C) Both A and B D) silk 6. ESD Bakelite Sheet is a kind of antistatic materials which is added anti-static agents in the production of Bakelite sheet, and effect Bakelite to achieve the best antistatic performance. • Insulation paper is specially made without addition of fillers. A dielectric, or electrical insulator , is a substance that is highly resistant to the flow of electric current. One of the first plastics made from synthetic components, Bakelite was used for its electrical nonconductivity and heat-resistant properties in electrical insulators, radio and telephone casings, and such diverse products as kitchenware, jewelry, pipe stems, firearms, and children's toys. A wide variety of bakelite electrical insulation board options are available to you, such as material, application, and type. Bakelite is first made synthetic resin which was used for commercial purposes. Bakelite is also available in sheet, tube and rod forms. Bakelite powder is obtained by mixing phenolic resin with sawdust, talc powder (filler), Urotropine (curing agent), stearic acid (lubricant), pigments and cooling in a mixer. Bakelite continues to be used for wire insulation, brake pads and related automotive components, and industrial electrical-related applications. Phenolic resins have to be reinforced with a filling agent. are some examples of bakelite rubber products. Air permeability is allowed in some insulators like cloth, paper. A) Bakelite B) Melamine C) Teflon D) None of these 4. In America's richest town, $500k a year is below average. Physical properties of an insulator. Answer: Insulator is the material that does not allow an electric current to pass through it. Metals like sodium (Na) are the best conductors. Silicon (Si) is a semiconductor---somewhere in between a metal and a non-metal. Bakelite definition: 1. a brand name for a type of hard plastic used especially in the past: 2. a brand name for a type…. It prevents us from electric shocks. A combination of formaldehyde and phenol leads to Bakelite. Choose the correct answer: Natural polymer occurring in plant is . The insulating materials belong to two large groups such as inorganic and organic. Bakelite rubber grip can also be found in the fitting machining operations. Alibaba.com offers 1,471 bakelite electrical insulation board products. The surface and volume resistivity value is 106-109Ω. For example, wood, mica, asbestos, rubber, etc. If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware. Radios, telephones and electrical insulators were made of Bakelite because of its excellent electrical insulation and heat-resistance. They are used as sheets, rods, tubes ans also mouldable granules. • The only exception are data and telephone jacks, antennae outlets and speaker wall sockets which cannot be mounted in the porcelain double cover. If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. An electrical insulator provides very high resistance so that practically no current can flow through it.
