Lead coating is one of the best materials to improve the service life of high voltage cables.
The continuous extruder is mainly used to cover wire and cable with lead or to cover rubber pipes with lead vulcanization.
In this unit, the lead material is transported from bottom to top by means of vertical rotation of the screw to achieve continuous extrusion, so that the thickness of the lead layer can guarantee the uniformity in the longitudinal direction of the lead pipe. Because the temperature of each part can be controlled strictly, the extrusion pressure and temperature can be kept constant, so as to ensure that the error value of lead thickness can be controlled in the minimum range.
Because the furnace, purification and heat preservation furnace and lead liquid transportation all adopt sealing system, the lead vapor diffusion is greatly reduced, and the environment pollution is basically eliminated.
This equipment is easy to operate and easy to master.The equipment also has the advantages of light weight, small area, low operating intensity.
