Problems solved by technology
[0002] The cables used in the existing marine engineering equipment are involved in harsh environments such as mud and oil in the ocean bottom, and changes in high and low temperature differences. The cables used in this environment need to be resistant to high and low temperatures, waterproof, flame retardant, Fire prevention, weather aging resistance, good flexibility, convenient use, safe and reliable use, etc.; while the cables used in existing marine engineering equipment are still traditional ordinary cables, so there are severe corrosion of the cables and short service life, which is harmful to the working Engineering equipment brings frequent maintenance and repair tasks, resulting in the failure to complete the operation plan on time, causing huge economic losses and hindering the development of national defense engineering construction

Embodiment Construction
[0016] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:
[0017] Such as figure 1 As shown, a cable for offshore oil engineering includes a cable core and a sheath. The cable core is formed by twisting several insulated wire cores 1. The outer periphery of the cable core is wrapped with a fire-resistant isolation belt 2. The cloth tape is wrapped around the cladding 3, the inner sheath 4 is set around the outer periphery of the cladding with the tape, the inner sheath is provided with a galvanized steel wire double-braided armor layer 5, and the galvanized steel wire double-braided armored layer is provided with chlorosulfonated Polyethylene outer sheath6.
[0018] Preferably, the gaps between the insulated wire cores are filled with hemp yarn.
[0019] Preferably, the inner sheath is an oxygen barrier and halogen-free inner sheath.
[0020] Preferably, the oxygen-insulating halogen-free inner sheath is ...
