COMPOSITE INSULATORS TEXPI/CYG
COMPOSITE INSULATORS TEXPI/CYG
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.
100 years later, in the 1980’s, an important innovation in insulators was introduced to the market, the COMPOSITE INSULATORS: With a fiberglass core, vulcanized organic composite housing and metal terminals, the COMPOSITE INSULATORS presented a much lighter AND pollutant-resistant design compared to traditional glass and porcelain insulators. Initially, due to the union between different materials, problems of mechanical and electrical performance were identified, but today the technology is mature, with insulators in service for more than 25 years with excellent performance even in very contaminated environments.
Although the cost of composite insulators is still less than the cost of their porcelain or glass equivalents, a small percentage of the cost of building a substation, transmission line or manufacturing electrical equipment, failure of this component can result in serious problems, such as accidents and prolonged shutdowns, with important economic and social consequences.
These are high-tech components: Hundreds of tests, development of new mixtures and factory refinement were necessary to reach the exceptional level of reliability that high quality composite insulators can provide today.
We at TEXPI Equipamentos have been supplying high quality composite insulators for more than 10 years for the most important substations, equipment manufacturers and transmission lines in Brazil and the world with excellent history of performance, reliability, durability and after-sales service.
We offer an unprecedented 30-year warranty (Q+30) for our composite insulators when applied with our electrical metal fittings for string insulators. Make your inquiry with us!
We work with all technologies in insulators: glazed porcelain, toughened glass and composites (HTV silicone rubber with fiberglass core). We are committed to serving our customers with excellence.
