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 DFW8-12 European-style high-voltage cable distribution box is widely used in distribution-network cabling projects. It features double-side door opening and uses butt-joint sleeves as the connecting busbar, with notable advantages of small length, neat cable layout and no large-span crossing of three-core cables. Its cable joints comply with DIN 47636; bolted fixed-type cable joints rated 630 A are generally fitted.
