JTT 876-2013 Filled Epoxy-Coated Steel Strand External Prestressing Bundle

Standard Overview

JT/T 876-2013 Filled epoxy-coated steel strand external prestressing tendon is a transportation industry standard of the People's Republic of China. It specifies the technical requirements for external prestressing tendons formed from filled epoxy-coated steel strand, covering the strand, the filling epoxy, protection and anchoring requirements of the tendon system.

Why It Matters for Flexible PV Brackets

• Filled epoxy-coated strand provides complete sealing of the seven-wire strand — high-concentration salt mist cannot penetrate inward, making it the recommended strand for coastal and offshore flexible brackets.
• External prestressing tendons are structurally analogous to flexible bracket main and anchor cables: both are exposed tension members with anchorages at both ends.
• The standard's requirements for the epoxy filling, sheathing and anchoring quality are a practical reference for flexible bracket cable system design and construction.
