About DLB Oberviechtach
DLB Oberviechtach is a manufacturer of multi-wire strands, stranded wires and ropes made of copper, copper alloys and aluminium. The portfolio comprises single wires, braided wires, squadded conductors, bunched strands, concentric strands (Unilay, Auto Unilay, conventional concentric, unidirectional concentric) as well as strands and ropes made of enameled wire. Production is carried out with heavy-drawing, single-wire drawing and multi-wire drawing machines, energy-efficient spooling, stranding and cabling machines, as well as torsion-free tubular and skip stranding machines. In addition to production, tinning is performed. Customers are national and international manufacturers of electrical cables, among others from the automotive industry, household appliance technology, installation and communication technology, mechanical engineering and alternative energy generation. Together with the BEHG Holding AG, DLB Draht und Litzen GmbH and KBE Elektrotechnik GmbH in Berlin as well as KBE Elektrotechnik S.C.S. in Sousse (Tunisia), the company forms a medium-sized corporate group. Production takes place at the Oberviechtach site in the Upper Palatinate.
