Rail Nylon Insulator

Rail insulators are used on both sides of the rails to adjust the gauge and used together with the fasteners and plays a very good role of insulation . They are suitable for high-speed or high-load trains , they are important fastener components. Because the material is an insulator, it is very wear-resistant and can act as a buffer.

Rail insulator is suitable for rails such as UIC60, UIC54, 115RE, 136RE, BS100A, BS80A, 90R, 75R, 50R, 60R. The material is PA6 or PA66 with a glass fiber content of 20% to 35%. These materials are UV resistant and can be used in natural colors or as required.

The properties of our rail insulators are as follows:

Technical Parameter	Unit	Technical Requirement	Value

Tensile Strength	Mpa	≥170	178
Elongation	%	≤4.4	4.0
Bending Strength	Mpa	≥250	290
Impact Strength (No gap)	KJ/m2	≥80	85
Melting Point	℃	250 - 270	270
Insulation Resistance	Ω	≥1×108	5×108
Glass Fiber Content	%	30-35	35
Hardness	HRR	≥110	118

PA66 content: Nylon 66.69%, glass fiber 30%, other 1%

We can provide E-type rail insulator, SKL rail insulator, Nabla rail insulator

1、E-type rail insulators

E-type rail insulator is used in E-rail fastening system. It is used with E-clips, rail shoulders and rail pads. Its function is to cushion the pressure of the passing train on the track and then return the rail to its original position. Equivalent to the rail pad under the rail.

2、 SKL rail insulators

SKL rail insulators are also called angle guide plates, used in SKL fastening systems, combined with SKL tension clips, screw spikes, plastic dowels, flat washers and rail pads.
