Tensile-resistant power cable with data information transmission function

Technical field

The utility model relates to a cable, in particular to a power cable with strong tensile strength and the function of data information transmission. It belongs to the technical field of wire and cable.

Background technique

At present, some large-scale mechanical equipment needs both powerful electric support and a large amount of data information transmission with the outside world during operation. Traditional power cables can only provide power but not information transmission. Traditional data information transmission cables can only provide information transmission but not power. This requires the use of two cables to accomplish the above task. Most cables have disadvantages such as difficult installation, high cost, and inconvenient use. With the rapid development of modern large-scale machinery and other equipment in the direction of high technology, cables with excellent tensile properties are required. Traditional cables have been far from meeting the above needs.
