Electrical insulators are fundamental elements in any electrical system, as they are responsible for separating the electrical conductors from the rest of the elements that make up the circuit. In this way, they prevent electricity from escaping and causing damage or accidents. In the case of low voltage insulators, they fulfil this function in systems that work with voltages of less than 1000 volts.

Innovations and technological advances in electrical insulators have significantly transformed their design, efficiency and applicability, addressing old and emerging challenges in electricity transmission and distribution.

Insulators are essential components in the electrical sector, as they ensure the safety and proper functioning of electrical installations. In this article, we will look at what insulators are, their types, the materials used in their manufacture, their role in the electrical sector and much more.

The use of insulators is essential in the transmission of electrical power. These components are responsible for supporting the conductors of cables and keeping them insulated from the ground and other elements. However, in certain extreme conditions, insulators can fail, which can endanger the safety of the electrical system and the people working near it. In this article, we will explore how insulators behave in extreme conditions such as fire, ice and other environmental factors.

High voltage electrical insulators are vital components in electrical power transmission and distribution systems. Isolators are devices designed to withstand high electrical voltages and isolate the electrical conductor from the tower support. In this article, we will explore the main features of high voltage insulators.

In our endeavour to minimise the environmental impact during production of our composite and porcelain insulators, and within our continuous improvement programs, we have started by obtaining the ISO 140001 certification, thus reinforcing trust for all parties involved.
