Insulated Rail Joint

Insulated rail joint is a compromise rail joint. Rail joint, commonly known as railway fish plate, it plays a role in connecting two rails. In general, rail joint is made of metal material, but insulated rail joint is a special type that made of insulating material. Specifically, insulated rail joint is made from high strength composite, which has advantages of corrosion resistance, rust prevention, ultraviolet-proof, non-conducting, non-conductive magnet. Compared to common rail joint, insulated rail joint can insulate electric current and thunderbolt. Due to its board application, railway track require insulated rail joint to be applied in more and more section.

Rail joint usually works with same standard steel rail. Like steel rail, insulated rail joint can be divided into insulated rail joint for light rail, heavy rail. For light rail, common sizes include 8KG, 9KG, 12KG, 15KG, 18KG, 22KG, 24KG, 30KG. For heavy rail, including 38KG, 43KG, 50KG, 60KG, QU70, QU80, QU100, QU120.Bonded insulated rail joint and Polyurethane insulated rail joint are two typical insulated rail joint on the market.

Sometimes called railway fishplates, rail joints are an important component of a rail track system to connect two rail tracks together. Three commonly used types of rail joints include:

• Bolted joints
• Compromise joints
• Insulated joints

As a rail joint, the bolted joints are usually used to join rail tracks together before the are welded. As to joining two rails with differing sections, the compromise joints are mostly used. And the insulated joints are always used as the bonded or non-bonded joints.

Although the perform of these three types of rail joints is different, they still have many similar features:

• Bolts and bars are all used and a discontinuity is created on the running surface of the rail track
• The discontinuity can accelerate track degradation around the rail joints while trains are running

Today the worldwide famous insulated rail joints are bonded insulated rail joints and polyurethane insulated rail joints.

Bonded insulated rail joints are mostly used to separate electric circuits in rails and turnouts. Because of widely used in continuously welded rails (CWR), the bonded insulated joints in rails must be ensured to transfer longitudinal forces arising in the railtracks. And insulated joints can also cut in square or angular.

The typical features of bonded insulated rail joints

• Up to 60&#; long and ensured the specified length
• Mostly used with A-490 bolts or huck pins (6 / 8)
• Conveniently used in worn rail or transition rail configurations
• Micro alloy joint bar

The typical features of bonded insulated joint kits

• Available as insulated or non-insulated
• Four, six or eight holes are available
• Long life and high performance
• Bulk packaging is available
• Furnished with high toe clearance designs

The polyurethane insulated rail joints is featured to a micro alloy joint bar sections. Through ultraviolet, ozone, weathering abrasion, or the shock and flexing stresses of heavy rail traffic, it is a specially formulated compound.

The dense polyurethane material bonded to the rail joints can provide superior insulation between the rail tracks and the joints.

Then they finally lead to a firmly structure, which can provide high-dielectric isolation for signal circuits. With the special design, the structure can provide years of heavy duty service and require little or no maintenance.

The process that the bolt hole insulated bushings into each insulated joint bar is in our factory, which can save a lot of time and increase working efficiency of rail track maintenance personnel when installing the joint on rail tracks.

The unique design also reduce the additional inventories of bolt hole bushings which our customers needed to carry in the past. Each insulated joint kit should be packaged together to simplify the storage and inventory.

Because of the insulated rail joints&#; bonded-to-steel construction, the joint flexes are added with both vertical and horizontal stress. The tough molded NEMA Grade G-10 end post provides wear-resistant easement between rail ends, and will not cold-flow under high temperature.

The product can accommodate special requests such as making toeless joints, making double insulated joints, and adjusting flange clearance for extraordinary rail wear. As to reliable circuit isolation, quick delivery, easy installation and lowest long-term cost are all available.
