It has direct yarn and continuous felt in various shapes. The alkali-free glass fiber has been designed and calculated by the mechanics. They are made of high-strength, alkali-free glass fiber-impregnated epoxy resins that are made through high-temperature forming dies. Of all of the insulated fishplates, one kind is typical product. Q235: The chemical composition of the steel (Smelting analysis) is less than or equal to 15kg/m and greater than 15kg/mĪccording to the models, they shall comply with Q235-A (or Class 3B steel) and Q255-A in GB700, respectively. Or, they are made of composite materials directly.Īccording to the materials，we can know that: They are often manufactured by the materials such as ordinary carbon steel hot-rolled Q235-A, Q255-A, QT400-18. Their national standard is GB11265-89 in China. They are manufactured in factories in a thermal process in order to wrap the insulation materials around the surfaces of all metallic components to ensure electrical isolation of each component. The insulated rail joint is a kind of special fastener for connecting the two ends of the rails. Raw materials of the insulated rail jointsĪs we know, the insulated rail joints, also known as fish plate, is a type of connecting fastener used for the connection between rails. the insulated fish plate) the railway components manufacturers china can supply include as follows:Ĭomplete application of the insulated rail jointsįor example, One set of glue insulation joint includes: 1 steel fish plate + 2FRP insulation liner + 4 (6) insulation sleeve (depends on the hole of the fish plate0 + 1 end post + bolt with nut and washer. Second, all the insulated rail joints can be manufactured of steel (It is furnished with a high durable polyurethane coating) or polymer composites. Their common advantages include: first, they offer the highest safety, reliability and durability in all climates. The railway components manufacturers china can produce various types of the insulated joints with different properties according to the type of force application, installation and manufacture. The insulated rail joints are required to determine the presence and position of a train for the purpose of safe signaling system control. Next, we will introduce the insulated rail joint specification. In addition, they should be made of a thermosetting material and cannot be processed twice. They have the features of corrosion resistance, rust resistance, UV resistance, non-conductive performance and non-magnetic performance. Most of the insulated fishplates are made of high-strength composite materials. The insulated fish plates are all made of insulating materials. The insulated rail joints are bolted rail joints containing bonded insulation materials wrapped around each contacting surface to electrically isolate them. They play a role in the joint of the track.
Railroad fish plates are commonly named as rail joints.
