PORCELAIN INSULATORS TEXPI/SPIW AND TEXPI/SINOMA
PORCELAIN INSULATORS TEXPI/SPIW AND TEXPI/SINOMA
As soon as electrical energy could be generated in large quantities, its use required adequate means to transmit that energy. Developing a component that isolates the live conductor was the main initial challenge. Although almost any solid non-conductive material in a dry environment can insulate several hundred or a few thousand volts, it was soon realized that it was difficult to design an effective insulator for use in humid and polluted environments.
The first insulators for electricity distribution networks developed in the 1880’s were based on the designs of insulators used in telegraph lines, using porcelain and annealed glass as raw materials. As stable insulating materials, very resistant to corrosion/deterioration, mechanically suited to application stresses, plentiful and cost-competitive, use quickly spread, becoming the most widely used insulating materials for electrical equipment and insulators.
Although the cost of porcelain insulators is a small percentage of the cost of building a substation, transmission line or electrical installation, the failure of this component can result in serious problems, such as accidents and prolonged shutdowns, with important economic and social consequences.
At first glance, PORCELAIN INSULATORS appear to be simple devices. They are, however, high-tech components: More than a century of studies, tests, development of new mixtures, ovens for proper firing and factory refinement were necessary to reach the exceptional level of reliability that high quality PORCELAIN INSULATORS are able to provide today.
For example, the spontaneous breakage rate of correctly sized high quality PORCELAIN INSULATION is less than one unit per 20.000 installed per year.
