Railway support insulators are also known as railway strut insulators. They are used to support or register live 25kv conductors or return conductors. The end fittings types of the railway support insulators are verified, according to the design of the railway companies or the replaced insulators. The top clamp can assemble with a certain diameter tube.
The support insulators should withstand the maximum working loads and the deflection value has strict requirement. When design the strut insulators, choosing a suitable core rod size should not only consider the cantilever strength, the deflection is also important. Except cantilever strength, compression load, torsional load and tensile load should be considered too.
The end fitting attachment of the insulator shall make sure the axial alignment, in order not to cause torsional or some other damaged stresses when the strut railway insulators are loaded.
Since the insulators are near the ground, bird pecking problem should be considered too.

Long Rod Insulator
Composite long rod insulators are used on overhead distribution or transmission lines. They are called composite suspension insulators too, and provide suspention or tension usage. Tension insulators normally require higher mechnical strength than suspension insulators.Learn More >
Line Post Insulator
In distribution lines, composite tie top line post insulators are the same as composite pin type insulators. The base fitting is the cap which assemble with the crossarm by steel studs. The head fitting can be steel type, or HDPE type, nylon type or silicone rubber covered types.Learn More >
