High Voltage Cable Branch Box

High Voltage Cable Branch Box (HV CBB) is a key outdoor power distribution device for 10–35kV cable networks. It integrates fully insulated/sealed cable joints (silicone rubber) and SF6 load switches, with IP33–IP68 protection. Compact, corrosion‑resistant steel/stainless enclosure, factory‑pretested, plug‑and‑play. Enables cable branching/ring networking, fault isolation, and maintenance safety. Ideal for urban grids, renewables, industrial parks, and underground projects.
