Intensive metal trunk line of heat conduction structure

Abstract

The invention discloses an intensive metal trunk line with a heat conduction structure in the technical field of power transmission and distribution metal trunk line conductor structures. The intensive metal trunk line adopts an ultra-thin good thermal conductor to deeply wrap each strand of conductor material which can be divided; the ultra-thin good thermal conductor is in direct contact with the metal shell to conduct and dissipate heat; full-length wrapping or partial wrapping is carried out on the conductor materials by using the ultra-thin good thermal conductor according to the product requirement; and the ultra-thin good thermal conductor and the metal shell are fixed through screws or rivets to avoid sliding. According to the intensive metal trunk line, the ultra-thin good thermal conductor is used for penetrating into the metal conductor to conduct temperature rise in time, so that the heat conduction efficiency of the temperature rise effect in the metal conductor is greatly improved, the heat dissipation capability of the metal trunk line is remarkably improved, the temperature rise effect of the metal trunk line is reduced, and the current-carrying capacity of the conductor is obviously improved.

Description

technical field [0001] The invention relates to the technical field of conductor structures of power transmission and distribution metal trunk lines, in particular to dense metal trunk lines with heat conduction structures. Background technique [0002] At present, the power transmission and distribution metal main line has high efficiency and is widely used as dense metal main line. The conductor generally includes three-phase four-wire or three-phase five-wire. After each phase conductor is wrapped with an insulating layer, the conductors are pressed together. The case is secured and wrapped. [0003] In order to ensure the insulation between different phases of dense metal trunk lines, the metal conductors of each phase are wrapped in multiple layers of insulating film. In order to avoid the pressure between the metal shell and the metal conductor from damaging the insulation layer, the standard process will add insulating tape between the metal shell and the metal condu...
