Depisa, partner for maintenance of high- and medium-voltage power lines

Thousands of kilometres of power lines spread across the country, distributing power to millions of supply points. However, its proper functioning also requires proper maintenance. To ensure the correct structural stability of the electric tower bearings, subject to extreme weather conditions, proper corrosion protection is essential. For this, Depisa has vast experience in this type of technical application and a team of professional, continually-trained experts to satisfactorily undergo these works at height, on live power lines. Professional technicians approved and qualified for treatment of this kind. Their expertise guarantees the proper application of the coatings necessary to protect the structure’s integrity. Therefore, major power sector companies (Red Eléctrica (REE), Iberdrola, EDF, Endesa, etc.) trust, and have trusted in, the company’s services.

Soluciones Reunidas is a business group bringing together Depisa, Siasa, Asturblast and Mktub. Depisa, its flagship company, has 45 years of experience and is market leader in anti-corrosion treatments for the Oil & Gas, Power generation and distribution, Mining, and Industry in general, sectors. Siasa is an anti-corrosion specialist in the naval sector and focuses on blasting, industrial painting, cutting and trimming power transport line routes.

Why corrosion?

Steel is one of the most-used materials in the construction of electric towers, due to its high resistance, market availability and impressive technical behaviour in the environments where installed. However, despite its resistance, corrosion must be fought. This is present in nature itself and can be enhanced if the support is installed in an environment with high levels of humidity and salinity.

Inadequate protection of these towers can have serious corrosion consequences and even, in extreme conditions, can produce catastrophic collapses. The Depisa staff, through a painting process, manage to protect steel from the harmful effects of corrosion, and effectively protect the structural steel’s integrity. This painting treatment includes an initial, comprehensive surface preparation work where coating must be applied.
