Electrical Market

Etal is a market leader with over 50 years’ experience in the manufacture of electrical contacts in a variety of alloys for low, medium, and high voltage, as well as for power generation and distribution equipment aimed at the electricity sector. Our products are manufactured following powder metallurgy procedures using top-quality raw materials so as to guarantee their chemical, electrical, and mechanical properties. To achieve this, we operate our own laboratories with highly qualified personnel. Additionally, we manufacture pads and contact assemblies, in different finishes, according to client requirements. Given the above, we have experience using a range of technologies, such as Computer Numerical Control (CNC) machining, assembly lines, and electroplating processes, all under the framework of a vertically structured company.

We are well aware that a key factor in the supply chain is that each client is assured of the resources that guarantee the company’s optimum operation; as a result, we are quick to respond to any specific customer requirements. This is why we operate our own manufacturing plant, plus a network of 10 sales offices located strategically throughout the country, thus ensuring both the sale and supply of materials in a timely manner.

The markets our products are aimed at include manufacturers of electrical equipment (such as switches, transformers, restorers, test benches, electric blades), electrical maintenance companies, and companies specializing in the generation and distribution of electrical energy.

Etal’s main objective is customer satisfaction, which we achieve through well-defined values such as commitment, responsibility, excellence, teamwork, communication, and integrity, along with highly personalized attention from our sales team and supported with the technical knowledge of our service staff, who have extensive experience in the field. We guarantee the quality required by our customers, whilst ensuring on-time product delivery, hoping in this way to promote long-term relationships with all our business partners.
