PS Type Clevis Plate

PS‑21100 adopts double‑plate parallel superimposed stamping‑integrated structure, no welding seams on main stressed sections. Two groups of through‑holes are arranged on the same central axis, ensuring force transmission keeps straight‑line direction. Main dimension parameters: plate spacing C=24 mm, matching bolt specification M24, centre‑to‑centre height H=100 mm, reference weight 2.4 kg. Each finished unit is supplied as complete set, including high‑strength bolt, hex nut and stainless‑steel split cotter pin. The cotter pin performs anti‑back‑off locking function after bolt tightening, preventing fastener dropping‑off under long‑term wind‑induced breeze vibration and conductor galloping. The inner wall of each hole is deburred and chamfered, avoiding shearing damage to galvanized coating of mating pins during tiny swing displacement. Hole‑position dimensional tolerance strictly complies with factory drawing standard, realizing seamless interoperation with P‑series parallel hanging plates, Z‑series right‑angle clevis, DT‑series adjusting links, DB‑type adjuster plates and L‑series triangular yoke plates in our product portfolio, supporting diversified hardware‑set assembly schemes

Base material selects Q235B hot‑rolled carbon steel sheet. Raw‑material incoming inspection covers tensile strength, yield strength and plate‑thickness deviation test to guarantee mechanical safety margin. Surface anti‑corrosion treatment applies hot‑dip galvanizing, complying with GB/T 13912‑2022 and ASTM A123‑19 international standards. Conventional zinc‑coating average thickness ≥65 μm. For coastal salt‑fog, offshore island and industrial heavy‑pollution working sites, thickened galvanizing ≥85 μm can be provided as optional upgrade. Except stainless‑steel split cotter pin, all metal components adopt hot‑dip galvanizing process. Each production batch undergoes sampling destructive tension test, minimum destructive failure load shall not be less than 210 kN. Our QC department archives dimension inspection report and galvanizing‑thickness test record for batch‑wise quality traceability. Custom service is available: adjust plate thickness, revise hole‑centre spacing upon special‑engineering client drawings

Pure co‑axial force transmission performance: Double‑plate parallel layout keeps pulling force strictly along central axis, will not generate additional bending stress, effectively prevent eccentric abrasion on insulator steel foot and steel cap caused by misaligned force direction.

Cascadable length compensation capability: Multiple PS‑21100 clevis plates can be connected in series to compensate accumulated dimension deviation of insulator‑string hardware groups. On‑site workers avoid cutting or modifying fittings under power‑cut status, shorten construction cycle.

Reliable anti‑loosening protection for high‑altitude operation: Matched stainless‑steel split cotter pin locks nut rotation freedom under cyclic alternating load aroused by wind swing, lower hidden risk of fastener falling‑off for overhead lines.

High‑level hardware‑system compatibility: Unified hole‑aperture and plate‑gap dimension matches mainstream power‑line fittings manufactured by our factory. Project purchasers can complete suspension‑string or tension‑string configuration within one‑stop supply chain, no extra transition adapter purchase required
