Problems solved by technology
Such a structure can block the high temperature in the environment where the cable is used, but it also blocks the heat generated by the cable transmitting electric energy, which will eventually cause the cable to age prematurely or affect the current-carrying capacity of the cable.
In addition, during power transmission, the electromagnetic induction caused by the imbalance of the magnetic field where the cable is located will cause hysteresis loss, causing the cable to heat up and also reducing the service life

Abstract
The invention discloses an internal heat dissipation high-temperature-resistant multifunctional cable. A cable core is formed by three wires, a supporting core body and three signal wires. Each wire comprises conductors located in the center and an insulating layer wrapping the conductors. Each signal wire comprises signal bodies located in the center and an insulating layer wrapping the signal bodies. The supporting core body is integrally formed by three metal sector rings in a circumferential mode, openings of the metal sector rings are outward, the included angle between the openings of every two adjacent metal sector rings is 120 degrees, and a longitudinal through hole is formed in the center of the supporting core body. The three wires are longitudinally arranged in the three metal sector rings respectively and tightly abut against the inner circumferences of the metal sector rings, and each signal wire is arranged outside the two corresponding adjacent metal sector rings and tightly abuts against the outer circumferences of the two adjacent metal sector rings. The cable core is wrapped by a taped covering, the taped covering is wrapped by a shielding layer, the shielding layer is wrapped by a heat insulation layer, and the heat insulation layer is wrapped by a jacket layer. The internal heat dissipation high-temperature-resistant multifunctional cable is good in internal heat dissipation performance and the shielding performance and resistant to the high temperature.
Description
Technical field [0001] The invention relates to the technical field of cables, in particular to a multifunctional cable with internal heat dissipation and high temperature resistance. Background technique [0002] Ordinary multifunctional cables use conventional polyvinyl chloride, cross-linked polyolefin and other materials as insulation and sheath materials. These materials will quickly age until the cable fails when the cable is overloaded or at high temperature. In this field, the basic idea to enhance the high temperature resistance of multifunctional cables is to select materials with a high thermal resistance coefficient as the thermal insulation layer, and increase the thickness of the thermal insulation layer, by increasing the thermal resistance of the thermal insulation layer. To insulating effect. Such a structure can block the high temperature of the environment where the cable is used, but it also blocks the heat generated by the transmission of electric energy by ...
