Our strain clamps deliver reliable mechanical performance, diverse structural configurations, and standardized markings. They undertake the core functions of conductor fixation and tension transmission for overhead lines and substations, effectively improving the overall stability and operational efficiency of power systems.
Strain clamps are used to fasten conductors and overhead ground wires (OGWs) for overhead transmission lines and substations. They connect to tower insulators via fittings and fix ground wires to towers. As key components for conductor anchoring and tension transfer, they ensure reliable line fixation under all operating conditions.
They are available in bolted and compression designs to suit different conductor specifications, site conditions, and tension requirements. Bolted types allow easy installation for small-to-medium cross-section conductors; compression types are ideal for high-strength fastening of large cross-section conductors.
With standardized markings to meet different current diversion ratios, strain clamps are applicable to branch line shunting scenarios, enhancing the flexibility and versatility of line connections.
They are perfectly matched with aluminum stranded conductors, aluminum conductor steel-reinforced (ACSR) cables, and steel strands. Model specifications correspond precisely to conductor cross-sections, fully meeting the fastening needs of various power conductors and ground wires.
Their bending radius is designed to be more than 8 times the conductor diameter, effectively reducing bending stress concentration, protecting conductor integrity, and extending service life.
Multiple structural options are available. Bolted types feature simple installation and easy later maintenance; compression types achieve high-strength connection via hydraulic compression, suitable for various construction environments and tension grades.
Unified alphanumeric codings clearly identify product type, applicable conductor parameters, and diversion functions, preventing model mismatch and lowering engineering selection difficulty.
Fully compatible with insulators, towers, and other power fittings. Suitable for aluminum conductors and steel strands of various cross-sections, meeting diverse fastening and connection requirements of transmission lines.
Strain clamps safely bear and steadily transfer line tension to towers and insulators, preventing loosening and slippage during normal operation, circuit faults, and extreme weather, and ensuring continuous and safe power transmission.
