AGICO Rail Plastic Dowel

A rail plastic dowel, also known as a rail plastic sleeve or rail plastic insulator, is a component used in railway track systems to provide electrical isolation between the rail and the fastening system, such as rail clips or screw spikes. It is made from plastic material and is inserted into the hole of a concrete sleeper (tie) or other support structure where the fastening system is anchored. The primary purpose of a rail plastic dowel is to prevent the passage of electrical current between the rail and the fasteners, enhancing electrical insulation and preventing corrosion. AGICO can provide rail plastic dowel of different types and specifications to meet the needs of customers.

About AGICO Rail Plastic Dowel

Rail plastic dowels are often used in SKL rail fastening systems, our rail plastic dowels are made of HDPE or PA66 + GF30%, and the product colors are white, black and dark brown. It depends on the different technical specification requirements of customers.

HDPE is a commonly used plastic material for rail plastic dowels. It has good electrical insulation, chemical resistance and durability. Known for its strong mechanical properties and impact resistance, HDPE is well suited for railway applications.

PA66 + GF30% can provide a balance of mechanical strength, insulation and other required properties.

Electrical Insulation: The primary function of rail plastic dowels is to provide electrical isolation between the rail and the fastening components, such as rail clips or screw spikes. This prevents the flow of electrical current and reduces the risk of interference with signaling and communication systems.
Material: Rail plastic dowels are typically made from high-quality plastic materials that offer excellent insulating properties. These materials are selected for their durability, resistance to environmental factors, and long service life.
Corrosion Resistance: By isolating the rail from metal fasteners, rail plastic dowels help prevent galvanic corrosion that can occur when dissimilar metals come into contact in the presence of moisture.
Ease of Installation: Rail plastic dowels are easy to install. They are inserted into the pre-drilled holes, and the fasteners are then secured through the dowels and into the sleeper.
Compatibility: Dowels are designed to match the specific rail profile and fastener type used in the rail system. This ensures proper alignment and fit.
Fire Resistance: Rail plastic dowels are often designed to be fire-resistant, which is crucial for ensuring the safety of the rail infrastructure and nearby structures.
