An NX-type wedge strain clamp crafted from high-strength aluminum alloy with a zinc-plated finish, designed for dead-ending and tensioning aluminum and ACSR conductors. Its wedge mechanism ensures a secure, vibration-resistant grip without conductor damage.
Jiujin Electric Power’s NX-Type Wedge Strain Clamp is engineered for reliable dead-ending of overhead transmission lines. Manufactured from corrosion-resistant aluminum alloy, this clamp features a precision-designed wedge and body system that applies uniform pressure on the conductor, ensuring optimal grip strength that increases with tension load. The zinc-plated steel components provide added durability and corrosion protection, while the aluminum construction minimizes galvanic corrosion when used with aluminum conductors. Its lightweight design simplifies installation, and the wedge mechanism allows for quick assembly without special tools. Produced in our Hebei facility, this clamp meets international standards for high-voltage transmission projects, offering exceptional performance in diverse environmental conditions.
