Flexibility: Easy to perform machining for cable input / output and customize the electrical enclosure to your needs. In our factories we have machining robots that allow us to do this work for you quickly, clean and economically.
Double insulation: Through the use of double insulated holes for wall mounting, the electrical equipment or switchgear assembly inside is completely isolated from the outside in order to avoid accidents and certify its electrical safety and insulation.
Benefits of the materials:

The reinforced thermoset polyester with which they are manufactured is the best insulating material available in the market. Ideal even in the most aggressive environments.
Self-extinguishing material. If there is a fire, the flame will not spread. Polyester is a thermostable and will not deform if there is overheating or fire.
Non-conductive material of electricity: Unlike metal boxes there is no danger in handling and we are not at risk of electrical shock (See accident video by download in the security section)
Easy maintenance They are ideal for outdoor use since they perfectly withstand the effects of weather in aggressive environments thanks to their material. It is non-hygroscopic and is protected against UV light, which allows an optimum operation of + 100º to -50º.
Total absence of toxic components and heavy metals fulfilling perfectly with the European Regulation of dangerous substances.
