Double Sheath Construction

Smartcore Steel Armoured Cable -

Double Sheath Construction


Direct Burial Cable is designed to be placed directly under the ground either by trenching or ploughing. The metallic cable is armoured with corrugated steel tape that provides good protection against rodents and allows the cable to retain outstanding flexibility for easy installation. The cable design is available in unitube (up to 24 fibres) and multitube single sheathed/ double sheathed construction (up to 96 fibres).

Loose tube containing fibres and jelly are stranded around a central strength member (FRP). Armour of corrugated steel tape provides the necessary strength required for direct burial applications.

  • The corrugated steel tape is co-polymer coated at both sides.
  • ECCS Tape armouring provides excellent rodent /rough terrain protection.
  • Meets IEC 60794, EIA/TIA, ITU-T, EN 187000, RUS 1755.900 & Telecodia GR-20 International standards.

Options Available

  • LSZH/FRPE as outer Jacketing Available.
