CE Certified 25 m/s Rod Breakdown Wire Drawing Machine with 13 Dies
LHD450-13DT rod breakdown line: payoff stand, main drawing machine, annealer, dancer, double spooler and drop coiler.
Product Summary
The LHD450-13DT is a rod breakdown wire drawing machine built by Jiangsu Listrong Mechanical & Electrical Co., Ltd. It draws Φ8 mm copper rod down to Φ1.2–Φ4.0 mm medium and fine wire at a maximum drawing speed of 25 m/s, acting as the first step in cable production. One line integrates the pay-off stand, main drawing machine, horizontal annealer, storage line tension dancer, double spool take-up machine, drop coiler and the lubrication and cooling water supply system. Conformity for the EU market is verified by ICG under CE certificate CE-JL26020401-AL-MD.
Key Features
13 Dies on a 450 mm Capstan
Thirteen dies run in a single row drum arrangement with quick die change. The reduction ratio is adjustable from 1.368 to 1.20, including the last pass, so outlet sizes can be changed without rebuilding the line.
Integral Cast Iron Box and Ground Gears
The main body uses an integral cast iron box with high-precision grinding gears and Japan NSK or NTN bearings, which improves machine running precision and service life.
Horizontal Annealer with Oil-Immersed Lubrication
Oil-immersed wire lubrication and a horizontal annealing device with 60V × 6000A DC annealing power help keep wire surface quality stable during high-speed drawing.
Double Spool Take-Up for Non-Stop Bobbin Change
Two 30 KW spooler motors serve PND500 and PND630 bobbins with fast reaction, no pollution and stable operation, so bobbins can be replaced while the cable line keeps running.
800 KVA Installed Power
A 280 KW main drawing motor, 75 KW final capstan motor and 18.5 KW-6P drop coiler motor support the 25 m/s drawing speed on this 40,440 kg unit.

Models and Options
Take-up bobbin options for this machine are PND500 and PND630, covering the bobbin sizes used in the wire and cable industry. The CE certificate CE-JL26020401-AL-MD covers the LHD450-13DT together with related LISTRONG drawing machine models such as LHD450-11DT, LHD450-9DT and their AL versions, so European buyers can reference one certificate number across a drawing line range.
Double spool take-up with drop coiler for PND500 / PND630 bobbins.
Materials and Structure
The machine is built around a main body integral cast iron box with high-precision grinding gears and Japan NSK or NTN bearings. Wire is lubricated by oil immersion, and the line is arranged as a single row drum layout for quick die change. The complete unit is composed of a pay-off stand, main wire drawing machine, horizontal annealer, storage line tension dancer, double spool take-up machine, drop coiler and lubrication and cooling water supply system, which supports stable running at high speed.
Horizontal annealer with 60V × 6000A DC annealing power.
Applications
The LHD450-13DT is suitable for the manufacturing industries of wires and cables, electrical equipment and new energy. It is responsible for drawing crude copper rods into standard medium and fine wires, serving as the first step in cable production, with an inlet of Φ8 mm and an outlet range of Φ1.2–Φ4.0 mm.
Customization
Listrong works with buyers on development design, whole plant planning and technical advice, and provides manufacture, installation, commissioning and after-sales service as one package, supported by a 15-engineer R&D team. Bobbin selection for this model can be specified as PND500 or PND630 to match existing spooling in the plant.
