3 units of 10 color coded 0.40mm cellular PE insulated pairs are stranded to form the cable core. The interstices are filled with a waterblocking compound. A dielectric binding tape and a longitudinally applied aluminum moisture barrier complete the core structure. An inner PE jacket is applied and is covered with a corrugated steel armor and an outer PE jacket. Ripcords are applied under the inner and outer jackets to facilitate removal.
