35KV Triple-layer Co-extrusion Dry-cure CCV Line, this production
line is suitable for Cu or Al stranded wire core to make XLPE
cables from 6kV to 35kV. It is of Semi-catenary type, in which the
triple-layer cable is heated by means of short-circuit method,
cross-linked with nitrogen gas, cooled by water is 14 sections of
tubes, heat released by warm water, then cooled in cooling water
trough. The XLPE cable is in accord with the standard of GB/T
1270b-2002 and GB/T 11017-2002.
