The water-blocking tape wraps around the cladding layer and the twisted shielding layer; each insulated conductor includes a copper wire conductor, and an insulating layer and a first water-blocking tape wrapping around the cladding layer are sequentially arranged outside the copper wire conductor. The utility model has a reasonable structure and has excellent water blocking performance, signal transmission performance and electrical performance, and the utility model is suitable for cables used in computer network systems.

Description

Water-blocking measurement and control cables for computer network systems

technical field

The utility model relates to an electric wire and cable, in particular to a water-blocking measurement and control cable for a computer network system.

Background technique

With the rapid development of modern science and technology, more and more computer network measurement and control equipment has been widely used in hydraulic engineering, water pipes, and hydropower projects. Moisture in the cable can easily penetrate into the sheath or penetrate into the cable from the damaged part of the sheath, which often leads to signal transmission failure and even accidents.

Contents of the invention

The utility model provides a water-blocking measurement and control cable for a computer network system. The purpose is to overcome the disadvantages that ordinary cables are easy to penetrate into the sheath or penetrate into the cable from a damaged part of the sheath, resulting in signal transmission failure or even accidents.

The utility model comprises four sets of wire cores twisted with each other, and a total water-blocking tape wrapping layer, a copper tape shielding layer, an inner sheath, an armor layer and an outer sheathing layer; between the four sets of twisted cores and the total water-blocking tape wrapping layer; each set of cores includes two twisted insulated conductors, each of which The second water-blocking tape wrapping layer and the twisted shielding layer are arranged in turn outside the insulated conductor; each insulated conductor includes a copper wire conductor, and the insulating layer and the first water-blocking tape wrapping layer are arranged in turn outside the copper wire conductor. layers.

The utility model has reasonable structure, excellent water blocking performance, signal transmission performance and electrical performance, and overcomes the disadvantages that ordinary cables are easy to penetrate into the sheath or penetrate into the cable from the damaged part of the sheath, resulting in failure of signal transmission and even accidents. The utility model is suitable for cables used in computer network systems.
