110KV/220KV Anti-Tracking PE Sheathing Compound for ADSS Cables

Basic Info

Model No.: LR3001(110KV)& LR3002(220KV)

Product Description

Product Description


The Anti-tracking PE sheathing compound LR3001&3002 is a specifically developed  sheathing compound for ADSS cables installed on the same pylons as HV power cables. It features excellent mechanical/physical properties, environmental stress cracking resistance, heat deformation resistance and excellent tracking resistance. With extreme fine and smooth extruded surface, this compound is used as sheath in tracking resistant ADSS cables installed in HV electric field.
Process Characterist


It is recommended that the plastic extruders with L/D ratio greater than 20:1 are used to extrude LR30 in order to obtain smooth and compact extruded surface and an extrusion rate in accordance with the requirements of the cable manufacturing process.



The temperatures for the individual extruder sections are recommended as follows: 







 Section 5


Die open 













The data in the above table are for information only. When L/D ratio less than 20:1 is used and the space between the barrel and screw is large, the extrusion temperature shall be increased or extrusion rate decreased accordingly.

It is important to minimize the stretch of sheath during the extrusion process. In order to reduce the internal stress of the sheath, the cooling trough shall be divided into sections to give rise to a temperature profile.

The optimized extruding temperatures depend on the details of the extruder, e.g. L/D ratio,compression ratio and construction of the screw.
