Abstract

A coiled tubing assembly 200 includes at least three cables 210-1 to 3, and may include three secondary cables 220-1 to 3. The main cable are supported on a core or bedding spine section 230 about which interlocking segments 240-1 to 3 are disposed (eg tessellated). Outer casing 250, which may include a weld joint 260, encases the whole assembly. The segments 240 include a rib side 244 and a groove side 242 which interlock with another segment. The segments have a curved exterior 248 and are configured to seat at least the main cables 210 in conjunction with the bedding section 230 on the interior 246. The bedding section 230 has a triangular cross section and formed from extruded thermoplastic. An end termination connection assembly (figs 4-8) having bellows for pressure balancing with the external environment and a method of connecting cables carried by coiled tubing including introducing dielectric material into an end termination assembly are also disclosed
