Structure of H-type parallel groove clamp

H-type parallel groove clamp is a compression structure, pure aluminum or aluminum alloy material, cannot be removed after installation. The clip is named after the clip's cross section resembles the letter H. With the help of special hydraulic pliers, the clamp can be pressed into a whole with the two connected wires. After crimping, the contact area is oval and cylindrical, and the appearance is relatively compact. Similar to the wedge-type parallel groove clamp, the compression process is controlled by the output pressure of the hydraulic clamp, which has less human influence. H-type parallel groove clamp can connect two wires of equal diameter and different diameter. The wire span in the same slot is generally 3-4. When the H-type parallel groove clamp is connected to the conductor, due to the circumferential force, the aluminum on the inner wall of the clamp is plastically deformed and embedded in the twisted gap of the outer layer of the conductor. The grip strength is about 40% -65% of the calculated breaking force of the wire.
