Insulator and conductor fittings for overhead power lines have many types. BS3288 gives the performance and test requirements of them. The overhead line fittings connect the conductor to the insulators and towers or apparatus, or protect and repair the conductors and so on.
Many types are available: suspension clamps, strain clamps, link fittings (clevis and tongue, ball-eye, ball hook, socket clevis eye, shackle, yoke plate...), splicing fittings (splicing sleeve, repair sleeve, parallel groove clamp...), protection and repair fittings (dampers, grading ring, arcing horn, spacer, armor rod...), guy fittings (guy clip, thimble...) Preformed fittings can provide more convenience when using to connect the electric power lines.
Mechanical strength and link dimension is important when choosing the fittings. Materials can be cast iron, cast steel, forged steel, copper, aluminum alloy..., the iron and steel type should be hot dip galvanized. All materials may be specially treated to get certain performance.
Electric overhead power line fitting types are various, we will choose detail types according to client’s requirement.
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 >
