Contents on the CD Rom

  • Insulator is a material that resists the flow of electric current. It is an object intended to support or separate electrical conductors without passing current through itself. An insulation material has atoms with tightly bonded valence electrons.
  • Steatite, cordierite, forsterite, magnesium oxide and aluminum oxide are among the wide varieties of raw materials used in the production of Du-Co ceramic insulators. Materials are tested and monitored throughout the production process. Production process includes Glazing, Firing, and Finishing.
  • Porcelain insulator production for high voltage application can be made by two possible methods. The conventional (Plastic) production process, The isostatic (developed within PPc group) production process. While the conventional (plastic) production process requires an operating time (for insulators without fittings) of 7-8 weeks, the isostatic production process requires only 1,5-2 weeks for the same insulator. The considerable time necessary for extrusion and drying before and after profile turning as necessary in conventional production - is reduced to almost zero by using isostatic production process.
  • Electroporcelain and toughened glass are the two types of insulators that are being used for high tension transmission lines and equipment throughout the world. The world market comprises of the power projects being set up mainly in the under developed and developing countries using electroporcelain and toughened glass insulators. In India also toughened glass insulators are being used in transmission lines.
  • Latest equipment such as microprocessor controlled firing kiln, photoscanning lathes, automatic grinding and airing machines and others available internationally for the manufacture of HT Insulators have been installed selectively by the industry to meet the product quality requirement. Computerised controlled tunnel and shuttle kiln are being used by a number of units. For firing of insulators, earlier consumption of furnace oil was around 440 ltrs per tonne of insulators. This has been reduced to around 230 ltrs per tonne resulting in almost 50% savings in energy requirements.
  • Regarding the insulating behaviour of composite insulators, the property of hydrophobicity is considered to be the most important factor. The dynamic processes of the hydrophobicity loss and recovery and their strong dependence on material (including basic formulation, filler, and additives) and on processing technology are fields of continuous optimization. Nowadays, around 95 % of insulators are manufactured with HTV-technology.
  • High-voltage insulators used for high-voltage power transmission are made from glass, porcelain, or composite polymer materials. Porcelain insulators are made from clay, quartz or alumina and feldspar, and are covered with a smooth glaze to shed dirt. The design of insulators often includes deep grooves, or sheds, that provides increased arc-lengths. Insulators made from porcelain rich in alumina are used where high mechanical strength is a criterion. Glass insulators were used to suspend electrical power lines.
  • The insulators are made from a proprietary, high-density polyethylene-based compound with a dielectric constant compatible with polyethylene covered conductors. They are designed to meet most of the dimensional, electrical, and mechanical requirements of the ANSI C29.5 insulator standards, even though this standard applies only to Wet-Process Porcelain Insulators. These insulators can be used in any application that calls for porcelain insulators requiring adherence to this ANSI standard.
  • The UK thermal insulation market, including building and industrial insulation, has demonstrated strong growth over the five year review period. The market has mainly been driven by demand for building thermal insulation in recent years, while the development of industrial thermal insulation has been moderate.
