Detailed Product Description

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
