Overview

The DFW-0.4 LV cable branch box supports urban-grid cable conversion. Installed outdoors, indoors or buried, it links power cables with box transformers, load-switch cabinets, switch-fuse combination cabinets and ring-main units, serving tapping, branching, relaying or switching duties and greatly easing cable networking.

Build & options

Floor-, wall- or pole-mounted variants cover most sites; indoor and outdoor types available
Body precision-fabricated and welded from cold-rolled or stainless steel — “three-proof + ventilation”: rain/snow-, corrosion- and insect-proof with heat-dissipating airflow; most internal parts stainless; ample cable sheaths and clamps at entries
Complete primary schemes: knife switches, switch-fuses or breakers freely chosen as in/out elements

Installation & transport

Optional installation/transport base frames (for 1–4 assembled units) prevent transit deformation and speed up site work: inspect to GBJ232 on arrival, drill per the manual without removing the frame, lift into place, set expansion bolts, then join horizontal busbars with the supplied link plates and land the secondary cables. Without frames, mount directly on level channel steel — straightness ≤ 1/1000, ≤ 5 mm over full length.
