Structural Description Of Wedge-type Tension Clamps In The Stripped Insulation Fixing Area

In the construction and maintenance of power distribution lines, dead end tension clamp is commonly seen in the treatment of conductor ends, and its structure and stress path are directly related to the treatment of the fixed area. This type of clamp achieves self-locking under force through the cooperation of the wedge and the housing, forming a continuously clamped state when the conductor is under tension.

Fixing Area Form and Treatment Logic

Clamp fiber optic dead end clamp is mostly used in fixing areas where insulation has been stripped. This structural arrangement is related to direct contact with the conductor's metal body. For exposed conductor sections, a stable friction interface is formed between the wedge and the conductor, concentrating the force path in the metal contact area, matching the mechanical load transmission requirements of the tension section.

Under certain engineering conditions, clamp fixed dead end clamp may also be adapted to different conductor cross-sections by matching the wedge core size to adjust the clamping range.

Wedge-shaped structure and conductor matching

Around the stripped insulation fixing area, the structural design exhibits clear zoning characteristics:

• Conductor stripping zone: forms a direct metal-to-metal contact interface

• Wedge-loaded zone: generates axial displacement with tension changes

• Shell bearing zone: bears the overall mechanical transmission path

This structural relationship causes the wedge-shaped tension clamp to exhibit a "the greater the force, the tighter the clamping" characteristic in the tension section, which is a typical wedge-shaped self-locking mechanism.

Structural extensions in engineering applications

The treatment of the fixing area of ​​the wedge-shaped tension clamp varies in different voltage levels and line types. Some models are suitable for insulated conductors and can be installed without stripping the insulation, while in scenarios involving high-reliability fixing, it is more preferable to treat the fixing area with insulation to form a stable clamping surface.
