Description

A computer cable for ships and water platforms

technical field

The utility model relates to the cable industry, in particular to a computer cable for ships and water platforms. the

Background technique

Marine cables are special cables for power, lighting, control, communication and other systems of rivers, oceans and water construction platforms. As the main mode of logistics transportation in the world, shipping has always played a pivotal role. Since entering the 21st century, the center of the world's shipbuilding industry has gradually shifted to Southeast Asia, and my country has gradually become the world's largest shipbuilding and processing area, promoting the development of the world's shipbuilding industry. the

Traditional computer cables for ships and water platforms have always been a difficult problem to solve the problems of oil resistance and corrosion resistance in the actual working environment. the

Utility model content

The purpose of the utility model is to provide a computer cable for ships and water platforms, which meets the performance indicators of low smoke, halogen-free, flame retardant and other performance indicators of ships and water platforms, and solves the problems of moisture resistance and corrosion resistance at the same time. the

The scheme of the utility model is as follows: a computer cable for ships and water platforms, including several conductor groups and insulating layers, and the plurality of conductor groups are respectively formed by twisting two conductors wrapped with insulating layers. The thickness of the layer is 0.6mm-0.7mm. The outer sides of the several conductor groups are respectively wrapped with inner tape layers. A color ribbon is arranged between the inner tape layer and the insulating layer. The shielding layer, the middle tape layer, and the outside of several conductor groups after wrapping the middle tape layer are wrapped with an outer tape layer and a total shield layer in turn. The sub-shield layer and the total shield layer are braided with tinned copper wires. The density is not less than 90%, and the total shielding layer is wrapped with an inner lining layer, an armor layer, and an outer sheath layer in sequence. the

The insulating layer material is flame-retardant cross-linked polyolefin. the

The middle tape layer is formed by wrapping a polyester film with a thickness of 0.05mm, and the lapping rate of the wrapping is 25%-30%.

The inner lining layer is made of extruded polyolefin with high flame retardant, low smoke, halogen free and corrosion resistance.

The armor layer of the utility model is composed of tinned copper wire braiding, which has a high weaving density and good mechanical protection performance, and can effectively protect the internal electrical performance structure of the cable from the influence of the external environment, and is made of flame-retardant cross-linked polyolefin material It is an insulating material with excellent flame retardant performance; the halogen gas released when the cable material is burned, the pH value of the gas aqueous solution and the conductivity are low, and it has low corrosion performance; the cable generates less smoke when it is burned, and it has wear resistance, tear resistance, Oil resistance, ozone resistance, corrosion resistance, high flame retardancy and other properties. the
