Description

technical field [0001] The patent of the invention relates to the field of cable technology, specifically a special-shaped monofilament intelligent conductor structure. Background technique [0002] It is usually a rope-like cable twisted by several or groups of wires (at least two in each group), 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 of the cable has the characteristics of internal electrification and external insulation. The cables include power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, and mining cables. , aluminum alloy cables, etc., which are composed of single or multi-strand wires and insulating layers, and are used to connect circuits, electrical appliances, etc. [0003] Optical cables have a wide...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the patent of the present invention is to provide a special-shaped monofilament intelligent conductor structure, which can not only effectively improve the conductor compression coefficient, reduce the outer diameter of the conductor, save the consumption of raw materials in the cable post-process, but also realize the real-time temperature measurement function of the conductor and adjust the conductor temperature. At the same time, its temperature-measuring optical fiber is placed on the outermost layer of the conductor. The optical cable can effectively avoid crimping when the conductor is connected. It is circular, and the gap between the cables is large, resulting in a large conductor diameter, which requires a lot of raw materials, and the cable runs at high temperature or the cable carries too much current, and the operating temperature exceeds the allowable value, which will accelerate insulation aging and affect the life of the cable. If the carrying current is too low, it will cause a waste of cable resources. At the same time, the temperature measuring optical fiber is placed inside the conductor, and the optical cable will be under pressure when the conductor is connected, which will affect the normal use of the optical cable.
