Triple Co-extruder Line ( 65-120-90) Silane Cross-linking Extrusion Line.

1.  Application

XLPE 6-35 KV 3-layer Co extrusion CCV line for cable is suitable for copper or aluminum wire core, making 6-35 KV voltage XLPE insulated cables. Arranging piping adopt the semi-hanging chain type, using crosslinking heating method, nitrogen cross-linked, water-cooled three-way cross-linking method were extruded production line, cross-linked structure of cable products meet the relevant standards GB/T12706-2002 or IEC Standard.
