Abstract:
1. A power cable for use on a drilling rig, comprising: one or more insulated high-conductivity conductors; electromagnetic shielding enclosing said high-conductivity conductors; a first polymeric sheath surrounding said electromagnetic shielding; a reinforcing layer of braided aramid fibers circumferentially surrounding said first polymeric sheath, said reinforcing layer (i) defining a reinforcing-layer aramid braid having gaps, (ii) providing coverage of between about 40 percent and 60 percent and (iii) having a breaking strength of at least about 10,000 lbf; and an extruded, second polymeric sheath surrounding said reinforcing layer, said second polymeric sheath filling the gaps in said reinforcing-layer aramid braid to thereby integrate said second polymeric sheath and said reinforcing layer.
