Cat7 soft cable for ocean engineering equipment local area networks and manufacturing method thereof

Abstract

The invention discloses a Cat7 soft cable for ocean engineering equipment local area networks and a manufacturing method thereof and belongs to the technical field of cables. The cable comprises four twisted pairs, wherein each twisted pair is twisted by two core conductors respectively with an insulating layer; each core conductor is twisted by seven equant tinned wires; a double-layer independent shielding layer is longitudinally wrapped outside each twisted pair, the inner side of the double-layer independent shielding layer is provided with an internal current introducing wire, and the periphery of the double-layer independent shielding layer is provided with an internal wrapping layer; and the four twisted pairs with the internal wrapping layers thereof are twisted into a cable core, an integral wrapping layer is arranged outside the cable core, an integral shielding layer is arranged on the integral wrapping layer, the inner side of the integral shielding layer is provided with an external current introducing wire, an external wrapping layer is arranged outside the integral shielding layer, a knitted shielding layer is arranged outside the external wrapping layer, an internal protective sheath is arranged outside the knitted shielding layer, an armored layer is arranged outside the internal protective sheath, and an external protective sheath is arranged outside the armored layer. The invention has the advantages of favorable insulating property, high strength, soft cable and interference resistance, and can be safely used as a signal transmission cable in construction of ocean engineering equipment local area networks.

Description

technical field [0001] The invention relates to a cable, in particular to a signal transmission cable for marine engineering equipment and a manufacturing method thereof. Background technique [0002] The International Organization for Standardization agreed to use a classification scheme similar to that developed by Anixter when formulating the relevant standards of the wiring system, and established the evaluation index "Categories". And each single component such as cables or connectors must conform to the corresponding category, which is Cat3, Cat4, Cat5..., Cat7 (category seven) is one of them, and category seven is the latest in the ISO 7 category / F class standard A kind of twisted pair, it is mainly to adapt to the application and development of 10 Gigabit Ethernet technology. Its transmission frequency can reach at least 500MHz, which is more than twice that of Category 6 and Super Category 6 lines, and the transmission rate can reach 10Gbps. At present, although t...

AI Technical Summary

Problems solved by technology

At present, Category 5 or Category 6 lines are used on marine engineering equipment. Due to the specificity of the environment and place where marine engineering equipment is used, the cables are required to be soft and easy to lay, with high tensile strength and resistance to complex electromagnetic environments. Currently, there is no suitable Category 7 cable. wire can be used; in the prior art, there is no report on the production method of the relevant seven types of wire
