ABSTRACT:
The invention relates to undersea cable transmission links including submerged repeaters, and more particularly it relates to a housing for such a repeater. The repeater housing includes a very rigid, watertight metal box (12) coated with an external polyethylene sheath (124, 125, 126) preventing the box from coming into contact with sea water, and electrically isolating it from the sea environment. The coated box is placed in a tubular casing (10) which is very strong in traction. The repeater includes a metal sleeve (130) placed inside the tubular casing (10) over the outer sheath of the metal box (12) and provided with studs (11) passing through the tubular casing (10) via suitable openings. The sleeve reduces the thermal resistance of the housing by short circuiting the thermal resistance of the tubular casing to a considerable extent.
