3/8" Galvanized Steel Wire Preformed Dead End
Guy grip dead end
The material used to create the Guy Grip dead end is usually the same material used in the harness that attaches to it. Commonly used materials include galvanized steel wire and aluminum-clad steel wire. The purpose of this product is for single pole in power distribution construction projects. The grip provided by this product is even and prevents twisting of strands. In addition, the clamping strength is guaranteed to be at least 100% of the ultimate tensile strength (UTS) of the strands. During the installation process, it is crucial to proceed with caution to ensure success. It should be noted that this product is intended for use by trained and skilled professionals only.

The high-strength wire is formed through a sieve and is made of a length of screw, like a normal spring. The thread pitch is several tens of times that of the pressure spring, and the inner diameter of the screw is smaller than the diameter of the strand or conductor. Due to the elasticity of the high-strength wire, when it is installed and wound around the strand, the helix creates a clamping force on the strand. This kind of wire made of helix is called preform wire. Parameters include: wire outer diameter, pitch, length, wire diameter and helical direction.
Preforms are made of high-strength steel wire. Commonly used materials are galvanized steel wire, aluminum clad steel wire, aluminum alloy wire.
what is preformed dead end?
To increase the grip of the preformed rods on the strand or wire, glue several preformed rods together as needed and grit the parts that come into contact with the strands.
In order to facilitate the installation of the sleeve U-shaped clamp, it is necessary to loosen a certain length in the middle of the glued preform, and take the center of the loosened section as the reference, and fold the preform in half according to the required radius to form two legs. The products made after this process are called prefabricated dead ends.
Prefabricated dead ends are widely used in power transmission and distribution lines. Its main function is to tension the wire and install it on the terminal tower. It bears the running tension of the line and other additional loads. For various types of wires, stranded wires or optical cables, etc., different types of preformed dead ends are designed for different occasions. Due to its special structure, it has excellent product performance compared with traditional bolt or compression clamps:
1. The stress of clamping the wire is evenly distributed along the winding wire section to ensure the clamping of the wire and avoid stress concentration causing damage to the wire.
2. The fixture structure installed on the wire can improve the vibration resistance of the wire and prolong the service life of the wire.
3. It is easy to install. The construction personnel only need to ensure that the wire clamp is evenly wound on the wire, without any tools, and the installation quality is easy to ensure.
