The new “MSM 83” with electronic controls is designed to draw rod wire made of copper to a finished diameter range of 1.38mm to 4.56mm if equipped with 11 drafts. The machine can operate at speeds up to 38m/s and is available in 11, 13 and 15 drafts. As the drawing capstans are placed on two levels, the MSM 83 is extremely short with a length of only 4.5m. The controls allow drawing with minimised slip, resulting in high quality wire surfaces and maximum energy savings. In addition, the optimised wire path and the innovative high pressure cooling of the drawing die holders contribute to a high wire surface quality. MSM 83 is operated by means of the standardised Niehoff Machine Interface touch-screen display with colour user interface and simplified navigation structure. Sensor technology makes it possible to use machine, production and process data according to Industry 4.0. With the new Niehoff “Digital Assistant+ 4.0”, machine, production and process data can be recorded. Thus, continuous process monitoring and machine condition analysis are possible.

The enterprise is developing three “D” series double twist stranders for spool sizes 1,250mm, 1,600mm and 2,000mm) as well as rigid stranders. The new “D 1252” double twist strander is foreseen for stranding and compacting (round and sector) class 2 conductors for energy cables up to 19 wires with a cross-section of up to 250 KCMIL (120mm²). The machine is also capable of stranding hard Copper and Aluminium alloy wires, bunching flexible conductors up to 120mm² and laying up LV insulated conductors. Thanks to its unique features, the machine can reach a maximum rotating speed of 2,000min-1 and a line speed of 300m/min. The machine features wireless telemetry for all signals (including encoders), the service proven energy-saving single bow design, automatic traverse with flange detection allowing spools to be perfectly wound, monitoring of bearings temperature and cradle vibration. Thanks to its design, a smooth cable passage enhances the quality of the produced conductor due to a straight conductor path from the second twist pulley to the haul-off capstan and due to a big diameter of pulleys and haul-off capstan. Strong compacting degree is achievable via a motorized compacting die with lubrication. And two pairs of compacting rollers are provided for best quality of sector shaped conductors. The machine is equipped with the highest automation and best production control offering perfect repeatable product quality, excellent efficiency and fast return on investment.
