Abstract
The invention discloses a radio frequency cable for ocean engineering. The radio frequency cable for ocean engineering comprises a cable core. The cable core comprises a V-shaped rubber frame. A sector-shaped main conductor is arranged above the V-shaped rubber frame. A fluoroplastic insulating layer is arranged outside the main conductor in an extruding mode, two control wire cores are arranged below the V-shaped rubber frame, each control wire core comprises two control conductors coated with silicon rubber insulating layers, and after the two control conductors are twisted with two thermoplastic polyurethane elastic bodies, a cross-linked polyethylene insulating layer is arranged in an extruding mode. After the cable core is twisted with three filling ropes, the cable core and the filling ropes are sequentially coated with a taped covering layer, a water blocking layer and an outer protective sleeve. According to the radio frequency cable, the V-shaped rubber frame is adopted, the firmness of the cable is guaranteed, and the main conductor can be differentiated from other conductors. The thermoplastic polyurethane elastic bodies serve as filling, so that the flexibility of the cable is increased; the filling ropes are adopted, so that the tenacity of the cable is increased.
