What are the reasons for the abrasion of screw extruder in cable equipment?
The normal wear of screw and barrel of Screw Extruder mainly occurs in the feeding area and metering area. The main wear reason is the dry friction between chip particles and metal surface. When the chip is heated and softened, the wear decreases.

Summary of wire and cable equipment
Under the same conditions, the time needed for the change rate of short-circuit current of wire equipment to exceed the maximum value under normal conditions is obviously shorter than the time needed for the amplitude of short-circuit current of wire equipment to exceed the maximum value under normal conditions.
