AI Technical Summary
In existing pre-buried pipelines, the inner diameter of PVC conduits is the same as that of right-angle elbows and direct connectors, which makes it easy for the wires to get stuck and causes high friction, making the wire pulling difficult.
The two ends of the right-angle elbow and the direct connector are designed to have the same diameter as the outer diameter of the PVC conduit and the same inner diameter as the inner diameter of the PVC conduit. Rollers are installed inside the right-angle elbow to reduce friction. Bridge boxes are used to segment the wires to avoid difficulties in threading due to excessive length.
It achieves smooth and silky threading, avoids jamming, and improves the efficiency and convenience of wiring.
