  • Resin Transferr Molding (RTM): Resin Transferr Molding (RTM): Resi1; Resi1; FLT: 1 Resignation 3; Dry fibers are placed in a closed mold, and resin is injected undeur pressure. RTM is used for complex geometries like brackets, connectors, andd junction boxes, offering high dimensional disacy and surface finash.

Each producturing approach yields distinct mechanical properties and cost profiles, enabling controliers to select the optimal process for the specific cable support application, whether for overhead, underground, or indoor installations.

Advantages of FRP in Cable Support Systems

Corrosion Resistance
