What are the different types of clamps used on transmission lines?
2025-08-10In overhead transmission line construction, various clamps are used to secure conductors and other components. The two most common types are suspension clamps and tension clamps.
-
Suspension Clamps: These are used at tangent poles and towers to support the conductor. They "suspend" the conductor and allow it to move freely with changes in temperature and wind, preventing damage from vibration.
-
Tension Clamps (or Dead-End Clamps): These are used at dead-end structures, such as substation entries, terminal towers, or angle points. They are designed to grip the conductor securely and hold it under the full mechanical tension of the line.
Other important clamps include armor rods for protecting the conductor at support points and parallel groove clamps for connecting two conductors. Our wide range of OHTL equipment includes all these types, designed for safety and durability.
