CHAPTER I INTRODUCTION Pollution is one of the main problems the world faces today. One of the reasons is the overload of non-biodegradable objects like plastics‚ cans and Styrofoam. The invention of plastics and Styrofoam made a huge change in our society and it helped us in many ways. But it is also one of the main pollutants that destroy our planet. Because of these we devised a way to recycle used Styrofoam‚ and this is to make glue out of it. This glue can help reduce the number of Styrofoam

and circuit breakers instead of oil and air because it can improve the power system reliability. SF6 can be used in different types of electrical switchgear such as Gas Insulated Switchgear (GIS). SF6 gas not only as arc-quenching medium but as insulation as well. With respect to the SF6 insulating gas pressure‚ there are two principal GIS designs: high pressure GIS functioning at about 405kPa‚ and low pressure GIS which is operating at 120kPa. While at higher voltage levels‚ the advantages of high

Wind the wire around the PVC pipe. Fix the ends of the wires to the insulation tape. Remove about 3 cm. of insulation from the wire using the tips of the paper knife. Measure the resistance of the wire using the ohm setting on the multimeter. 2. Connect the batteries in series using

will still be options offered for each new product‚ however with a much more streamlined selection process. The basic steps of the manufacturing process for all these doors are (1) roll forming and press‚ (2) cutting and panel formation‚ (3) insulation‚ (4) component installation. It has been estimated that the capacity that can be allocated in these four processes are 20%‚ 25%‚ 18%‚ and 30%‚ respectively. That is‚ for example‚ 20% of the total capacity for the roll forming and press process

some of the important ways to save energy during this winter. Energy Audit: First step towards the cost saving exercise is the energy audit. A simple energy audit includes examining your home including heating and cooling systems‚ appliances‚ insulation‚ air leaks and lighting. Energy Audit attempts to balance the total energy inputs with its use and eliminating waste or cutting back unnecessary energy use. Replace old appliances with new Energy Star rated versions.

Rat tail joint A rattail joint is used with wiring that is placed into a junction box or conduit. Once again‚ about 5 inches of insulation is removed from both sides of the joint. The two sections of wire are simply crossed into an "X" and twisted together so that they form one section of twisted wire pointing straight up from the endpoints of the wires’ insulation.

His Role in Electrical Manufacturing” by N.R. Maleady The article is about the role of chemical engineer in manufacturing transformers in the electrical manufacturing sector. The important components of the transformer are copper wire‚ cellulosic insulation‚ insulating varnish and dielectric liquid. Wire enamel or resin is the insulting structure for copper wire. The resin can either applied as a solution or in solventless form. Mechanical arrangement and proper temperature between each dip are needed

Foam concrete advantages Foam Concrete is normal concrete with bubbles of air inside. Therefore it has the same characteristics with many additional advantages. CLC (foam concrete) blocks are used for building cottages‚ wall insulation in multistory buildings and internal partitions. Also CLC can be produced and poured for floors and roofs on-site. In roofs it can be used because of very good insulating and lightweight. For floors CLC offers faster installation and a less expensive option because
