The Tension Strain Clamps for Cable Fittings are engineered to securely anchor conductors and ensure stable wire tension in overhead power transmission and distribution systems. Manufactured with high-strength metal materials and treated with corrosion-resistant surface finishing, these strain clamps provide long-term performance under mechanical stress and outdoor exposure. They ensure safe force transfer without conductor slippage, making them essential hardware for utility networks and suspension points in line construction..
Strong mechanical tensile capability
Anti-slip gripping without conductor damage
Corrosion-resistant design for outdoor installations
Compatible with multiple conductor sizes and materials
Stable long-term mechanical performance
The Tension Strain Clamps are commonly used in:
Overhead transmission and distribution lines — Used for conductor anchoring and load bearing.
Utility pole and substation wiring — Ensures safe tension and secure wire connections.
ABC (Aerial Bundled Cable) systems — Provides reliable tension support during installation.
Long-span line construction — Suitable for mountainous or extended distance installations.
