Railway tension insulators are intended to be cut into a tensioned conductor. They separate one electrical section from another or from an earthed structure.
Since the tension insulators are used on the railway catenary lines, expect the tensile strength, torsion strength is also important, to meet the tortional load, choosing a bigger fiber glass core rod is necessary than transmission long rod insulators.

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 >
