What are the types of fish plate in railway?
Standard Fish Plates
These are the most common type of fish plates, designed for general use in railway track construction.
They are manufactured to standard sizes and specifications, and can be used with a variety of rail types and weights.
Insulated Fish Plates
Insulated fish plates are designed to provide an electrical insulation barrier between the rails.
This is important in areas where electrical signaling or power systems are in use, as it prevents the flow of current between the rails and potentially causing damage or interference.
Bulged Fish Plates
Bulged fish plates have a slightly convex shape, which helps to distribute stress more evenly across the joint.
This type of fish plate is often used in areas where the track experiences high levels of stress, such as at bridges or in curved sections.
Compromise Fish Plates
Compromise fish plates are designed to provide a compromise between strength and flexibility.
They are often used in areas where the track needs to be able to withstand both axial and bending loads, such as at transitions between different track types or in areas with complex track geometry.
Glued Insulated Fish Plates
Glued insulated fish plates combine the electrical insulation properties of insulated fish plates with the strength and durability of glued joints.
They are used in areas where both electrical isolation and high structural integrity are required, such as in subway systems or light rail transit networks.
Specialty Fish Plates
There are also specialty fish plates designed for specific applications, such as for crane rails or for use in overseas markets.
These fish plates may have unique shapes, sizes, or materials to meet the specific requirements of the application.
