The electrical metal fittings (for string insulators) is responsible for fixing the conductor cables (through the insulators) and surge arresters to the metallic structures (towers) that make up the electricity transmission lines. In addition to the direct application of providing the necessary mechanical resistance against the efforts that the installation will undergo over time in extreme situations such as winds, storms and even blizzards and earthquakes, quality electrical metal fittings also has an important role in controlling the intensity of the electric field, helping the good performance of the insulators connected to them.
In this sense, the proper set design, together with the good finishing of the component parts, is essential to obtain high quality insulating chains and superior performance, which reduces unwanted and costly shutdowns for the transmission line owner and society.
We at TEXPI Equipamentos have already supplied more than 5 thousand kilometers of metal fittings for string insulators for transmission lines in all regions of Brazil with an excellent track record of performance, reliability, durability and after-sales service. Our biggest reference is the supply of more than half of all metal fittings for string insulators on the Project HVDC ±800 kV Xingu-Rio, the largest transmission line in Brazil and the second largest in the world.
Make your inquiry with us! We work with metal fittings for string insulators in conjunction 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.
