The uniform force fluctuation at each end of the cable ensures a consistent cooling rate.

Description

Technical Field

[0001] This utility model relates to the field of wire and cable manufacturing equipment technology, and more specifically, to an extruder for preparing a buffer-protective composite stranded copper conductor. Background Technology

[0002] The power cable sheath extruder is a mechanical device used to produce power cable sheaths. During use, it can heat and melt the sheath material, apply the sheath material to the surface of the cable, and then extrude it. Applying the sheath to the surface of the cable not only prevents moisture and dust but also avoids mechanical damage to the cable.

[0003] After the cable is wrapped in a sheath and extruded, it needs to undergo multi-stage cooling. During cooling, in order to prevent water from entering one end of the cable, workers need to lift one end of the cable with external tools. The manual lifting method is time-consuming and laborious, and the fluctuation of the manual operation force leads to inconsistent cooling rates.

[0004] In view of this, an extruder for preparing a buffer-protected composite stranded copper conductor is provided to overcome the above-mentioned defects. Utility Model Content
