3. Structural Types of Waterproof Cables

(1) Single-core Cables

• For single-core cables, a semi-conductive water-blocking tape is wrapped around the insulation shielding layer, followed by a common water-blocking tape, and then an outer sheath is extruded. To ensure full contact with the metal shielding layer, only a semi-conductive water-blocking tape is wrapped around the insulation shielding layer, with no water-blocking tape wrapped outside the metal shielding layer. Depending on the required level of waterproof performance, the filling material can be ordinary or water-blocking. The inner lining and outer sheath materials are the same as those described for single-core cables.

(2) Aluminum-plastic Composite Tape Layer

• A longitudinal aluminum-plastic composite tape layer is applied as a waterproof layer inside the outer sheath or inner lining.

(3) HDPE Outer Sheath

• A high-density polyethylene (HDPE) outer sheath is directly extruded around the cable.
