DFW-0.4 LV Cable Branch Box
Companion box for urban cable conversion: taps, branches, relays or switches LV cables among box substations, switch cabinets and ring units — stainless build with rain-, corrosion- and insect-proof ventilated design, −50…+60 °C.
- 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/s
- Complete primary schemes: knife switches, switch-fuses or breakers freely chosen as in/out elements
A cleaner, more reliable approach to MV switching
The HP-ELS series replaces SF₆ with environmentally friendly insulating media while keeping the proven safety and performance utilities expect from gas-insulated switchgear.
Product Overview
The DFW-0.4 low-voltage cable branch box is supporting equipment for urban-grid cabling upgrades. Installable outdoors, indoors or underground, it connects power cables with box-type transformers, load-switch cabinets, load-fuse combination cabinets and ring-main supply units, serving as tapping, branching, relaying or switching to greatly facilitate cable networking.
