Strain clamps, also known as dead-end clamps, are essential fittings used in overhead transmission and distribution lines. They are designed to securely anchor conductors or ground wires to tension towers and poles, transferring the full mechanical load of the conductor without causing damage to the cable.
Made from high-strength aluminum alloy and galvanized steel hardware, strain clamps combine excellent mechanical reliability with superior corrosion resistance. Their precision-engineered design ensures firm gripping power, minimal electrical resistance, and long service life even under severe environmental conditions such as high winds, heavy ice, or coastal salt pollution.
Strain clamps are available in both bolted type and compression type, suitable for different voltage levels and installation requirements. Typical applications include dead-end connections, angle tension points, and terminal anchoring of overhead conductors in transmission and distribution networks.
By providing stable mechanical support and safe electrical performance, strain clamps play a vital role in ensuring the reliability and efficiency of modern power systems.
