Single‑wire tensioner (top‑mounted)

Suitable for securing conductors at the top of post insulators and pin-type insulators. Applicable conductor size: 10–300 mm². 1. Internally constructed with stainless steel; contact areas with wires and cables are molded with insulating material, offering excellent resistance to aging, low temperatures, sunlight, acids, alkalis, and rain, ensuring robust durability. 2. Components feature a well‑designed structure that closely matches the geometry of porcelain insulators, providing secure and reliable fastening. 3. Fully insulated design prevents damage to conductors, ensuring safe and stable grid operation. 4. Compatible with most pin‑type insulators used on 10 kV lines, including P‑series, PQ‑series, S‑series, SC‑series, and other common series.

Export-type strain clamp

Product Applications The PA series products are designed for securing and tensioning conductors at the terminals or both ends of tension sections of ABC conductors and overhead insulated conductors. Structural Features - The housing is die-cast from high-strength, oxidation-resistant aluminum alloy, with no hysteresis losses. - The wedge core is made of high-strength engineering plastic, offering excellent insulation performance. - Conductors can be installed directly without stripping the insulation layer. - The wedge‑shaped design ensures simple, reliable installation.

Safety Backup Wire Clamp

The three-span wedge‑type backup protective clamp, installed at critical crossing points of high‑voltage transmission lines, shares the mechanical and electrical load with the compression strain clamp, thereby enhancing the line's ability to prevent conductor breakage and string drop in "three‑span" sections. As a reinforcement device for hardware in "three‑span" transmission lines, it increases the overall system safety factor. Should the compression strain clamp fail, this backup clamp can prevent conductor sagging and subsequent cascading failures, buying valuable time for emergency repairs. It is suitable both for addressing the dual‑bundle, dual‑suspension configuration in tension sections of transmission lines and for retrofitting straight‑line suspension structures with dual‑bundle, dual‑suspension arrangements, while maintaining a conductor grip strength of no less than 40% of the rated tensile strength (RTS).
