Novel special marine cable

Abstract

The invention discloses a new special special cable for sea, which comprises a cable core, a fixed buffer frame, a wrapping layer, a water-blocking buffer layer, a water-blocking isolation layer, a shielding layer, a pressure-resistant layer and a sheath layer. On the fixed buffer frame, the wrapping layer is wrapped on the outside of the fixed buffer frame, the water-blocking buffer layer is wrapped on the outside of the wrapping layer, the water-blocking isolation layer is wrapped on the outside of the water-blocking buffer layer, and the shielding layer is wrapped On the outside of the water-blocking isolation layer, the pressure-resistant layer is wrapped outside the shielding layer, the sheath layer is wrapped outside the pressure-resistant layer, and the outside of the cable core is provided with a first insulating layer and a second insulating layer. The present invention adopts a four-layer waterproof design of wrapping layer, water-blocking buffer layer, water-blocking isolation layer and sheath layer, which greatly improves the water-blocking function of the cable. The additional design of the fixed buffer frame can make the cable When the whole is deformed, the cable core is firmly fixed in the installation groove, and the coaxial cable core will not be misaligned and squeezed each other.

Description

technical field [0001] The invention relates to the field of electric wires and cables, in particular to a new special special cable for sea use. Background technique [0002] The cable is usually a rope-like cable made of several or several groups of wires, each group is twisted with at least two wires, each group of wires is insulated from each other, and is often twisted around a center, and the entire outer surface is covered with a high degree of insulation the covering layer. Special cables are a series of products with unique properties and special structures, which are equivalent to ordinary wires and cables with a large quantity and a wide range. They have the characteristics of high technical content, strict service conditions, small batches, and high added value. The cables used for offshore operations require good waterproof performance. If the waterproof performance is poor, the transmission signal will be easily disturbed, and the expected effect of detection ...
