Triple arc multi hole is a specialized three-way diversion accessory for cable tray wiring systems, suitable for various mainstream cable trays such as trough, ladder, and tray. It is widely used in wiring projects such as industrial plants, building electrome chanical, computer room weak current, municipal power, etc. It is mainly used for line branching, diversion, and turning transition construction. The product adopts a curved streamlined integrated design, abandoning the rigid structure of traditional right angled tees, making the cable diversion transition smoother and softer. The design of the porous structure on the board is scientific, with excellent ventilation and heat dissipation effects. It is also convenient for on-site drilling and fixing, threading and organizing, and is suitable for various installation conditions. The arc transition structure can effectively protect the surface of the cable, avoid excessive bending and compression wear of the cable, reduce line losses, and improve the overall wiring safety factor. This accessory has standard dimensions, high docking accuracy, easy disassembly and assembly, and good fit, which can effectively improve construction efficiency. The wiring direction is regular and transparent, without dust accumulation or dead corners, making it convenient for later line inspection, maintenance, and expansion and renovation. It is an indispensable high-quality diversion and transfer accessory in the fine wiring engineering of electromechanical systems.
