Problems solved by technology

[0002] It is extremely important for the cables used for offshore operations to transmit electric energy normally, accurately transmit signals, and have clear detection images. Due to the particularity of offshore operations, the cables are often pulled and broken, and the waterproof performance is not good, which may easily cause the transmission signal to be disordered and fail to achieve To Probe Study Expected Effects
Ordinary cables have a single function, do not have vertical and horizontal water blocking functions, and do not have seawater corrosion resistance, high pressure resistance, mud and abrasion resistance, tensile and drag resistance properties, so they cannot be used at sea

Abstract

The invention relates to a sea-dedicated special cable and to cable structural field. The sea-dedicated special cable comprises a plurality of insulating wire cores. Each insulating wire core comprises twisted tin-plated copper conductors. Insulating layers are disposed on the peripheries of the twisted tin-plated copper conductors. Waterproof glue filling layers are disposed between the insulating layers and corresponding twisted tin-plated copper conductors. A waterproof wrapping tape is disposed on the peripheries of the insulating wire cores. A waterproof yarn mixing filling layer is arranged between the waterproof wrapping tape and the insulating wire cores. An aramid yarn weaving layer and a tin-plated alloy wire woven shielding layer are disposed on the periphery of the waterproof wrapping tape. An armor double-layer slurry-preventing outer sheath is disposed on the periphery of the tin-plated alloy wire woven shielding layer. Besides a transverse and vertical waterproof function, the sea-dedicated special cable also has advantages of seawater corrosion resistance, high voltage resistance, oil resistance, slurry resistance, and excellent wear-resistant, tensile, and hauling-resistant performance.

Description

technical field [0001] The invention relates to the field of construction of cables. Background technique [0002] It is extremely important for the cables used for offshore operations to transmit electric energy normally, accurately transmit signals, and have clear detection images. Due to the particularity of offshore operations, the cables are often pulled and broken, and the waterproof performance is not good, which may easily cause the transmission signal to be disordered and fail to achieve To detect the expected effect of the study. Ordinary cables have single functions, do not have vertical and horizontal water blocking functions, and do not have seawater corrosion resistance, high pressure resistance, mud and abrasion resistance, tensile and drag resistance properties, so they cannot be used at sea. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a special special cable for use i...
