P Clevis

P-80 parallel clevis is a small connecting fitting matched for low voltage lines. It is integrally stamped and covered with thick galvanized coating. Compact and easy to install, it has been widely applied in substation and light transmission line construction. P-80 parallel clevis connects substation equipment and insulator strings side by side, and extends and adjusts tension and corner insulator strings on transmission lines. It can be matched with wedge clamps, slot insulators and other power hardware during construction. Buyers can select P-type clevis based on actual site conditions. This fitting works well for low voltage circuits to fulfill regular connection demands with lower overall costs. Its single-plate design suits single-board connection work with simple assembly steps. It fits narrow and compact wiring space without interfering with surrounding hardware, making it a cost-effective choice for small and medium projects with limited budgets.

P clevis features compact size and simple single-plate structure, ideal for connection points with light load and limited mounting space. This series covers load grades of 70kN, 100kN, 120kN and 160kN, capable of bearing moderate tension and pressure on low voltage power lines. Site workers can string suspension insulators and fix them on towers to link wire clamps and insulator sets on straight and angle towers. It is also applicable to working conditions with strict limits on the size and weight of connecting fittings. If the load and installation environment cannot match P-type clevis, customers may take PD-type hanging plates as an alternative. Though they share partial application scenes, their structures differ greatly. Safety performance should be the top priority during selection, followed by cost control to guarantee stable long-term operation of power lines.

Common P clevis models include P-0770, P-1080, P-1290, P-16100, P-21100 and P-25120. Regular maintenance can extend service life no matter which specification you adopt. Operators need to check the intactness of galvanized coating every quarter and deal with rust or surface damage timely by polishing and recoating epoxy zinc-rich primer. Wipe dirt with soft cloth and neutral detergent under power-off status to avoid coating scratches caused by hard brushes. Check the anti-drop slots of stainless steel pins quarterly and refresh galvanized layers every two years. Inspect all insulator connections after thunderstorms and test potential difference between clevis and matched hardware. Clear ice loads in winter to prevent plastic deformation from overload, and reinforce all P clevis before typhoon seasons. Separate stacked products with PE films and keep stacking height under 1.5 meters to avoid coating abrasion.

The core gap between P clevis and PD clevis lies in their structures, which further leads to different performance and applicable scenarios. P clevis is a double-plate parallel bracket made of two parallel steel plates, mostly matched with slot insulators or used to extend the length of tension insulator strings. PD clevis is a single-plate fitting processed from one whole steel sheet. It mainly assembles with wedge clamps, can be fixed on tower collar flanges, and works with double-plate hardware to extend overall connection length.
