Railway insulators Solutions

Railway insulators Solutions

Poinsa is a company dedicated to manufacture and distribution of porcelain, ceramic and polymeric electrical insulators founded in 1978. It is part of a business group that combines its efforts to become a benchmark among the main European manufacturers of ceramic and polymer insulators. At Poinsa we are experts in the manufacture and distribution of safe and high-performance silicone/polymers and porcelain railway insulators. A modern and efficient transport infrastructure network is the key to competitiveness and development for a country. Poinsa produces catenary insulators, both porcelain and silicone insulators, of the highest quality for the railway sector. Poinsa is currently certified in ADIF (Spain), ProRail (Netherlands), Deutsche Bahn (Germany), Bane Nor (Norway) and many other countries. At same time, Poinsa has the flexibility of designing and manufacturing insulators according to every customer request, always assuring the fulfillment of the required technical specifications.

Polymeric Electrical Insulators

Polymeric Electrical Insulators

High quality polymeric electrical insulators. We constantly invest in the latest technologies to continue improving the quality of development of our high, medium and low voltage insulators, which so far have achieved great results, satisfying our clients in the railway, apparel and transformer markets. Raw Materials of Polymeric Electrical Insulators Acid resistant ECR fiberglass core.  Composition We use many glass filaments to provide high mechanical resistance and make them extremely thin. They are impregnated with epoxy resin, a thermosetting polymer used in the electrical sector for its dielectric properties. Manufacturing process Through vacuum extrusion and compaction at high temperatures. Acid resistance test Making small cuts in core at 12 mm depth. HN03 – 1 N Applied Voltage: 40.5 / = 23.4 kV: 7,200h for 300 days. Tensile strength: 10,400 kg / cm3, decreases by 5% Forged fittings in C45 steel, hot-dip galvanized. Poinsa design Electrical optimization of the shape. Free of electric discharges. Completely silicone coated. Total protection of the triple point. Galvanized with zinc thickness greater than 80. Conventional design Electric shock. Triple point unprotected. Deposition of pollutants that cause erosion. Silicone: SILICON + KETONE Silicone products: LSR liquid silicone rubber with high hydrophobicity. Maintenance of hydrophobicity: Characteristic property of silicone rubbers that is an important advantage for outdoor applications, making silicone a superior product to other materials. Hydrophobicity recovery: New silicone oligomers emerge on the surface over time, recovering their hydrophobic character. Resistant to erosion and pollution. Tear resistance increased by the primer process with organic product highly adherent. Transmission of hydrophobicity: The oils that come to the surface impregnate the deposited pollution and make it hydrophobic...
