Abstract
The invention relates to a method for manufacturing an insulated conduit bus. The insulated conduit bus comprises a conductive metal tube, a first conductive shielding layer arranged around the conductive metal tube and an insulated layer arranged around the first conductive shielding layer. The method comprises the following steps: the conductive metal tube is provided; a shielding insulated tube is prepared, the shielding insulated tube comprises the first conductive shielding layer and the insulated layer, wherein the first conductive shielding layer and the insulated layer are formed into a whole body; and the shielding insulated tube is sleeved on the conductive metal tube. The invention also relates to an insulated conduit bus, which comprises the conductive metal tube, a first conductive shielding layer arranged around the conductive metal tube and an insulated layer arranged around the first conductive shielding layer; wherein the first conductive shielding layer and the insulated layer are integrated to form the shielding insulated tube.
Description
technical field [0001] The invention relates to the wide use of insulated conduit bus bars in medium-to-high voltage and high-current transmission lines and a manufacturing method thereof. Background technique [0002] At present, insulated conduit busbar technology is widely used in medium and high voltage and high current transmission lines at home and abroad. Under the requirement of a certain temperature rise in the high-voltage and high-current line, the solid metal wire has low current density and low utilization rate of metal materials. The patent (ZL 200710027035.4) has tested the current density that copper tubes with different wall thickness can achieve: the current density can reach 2.0 (A / mm 2 ); the current density can reach 3.0(A / mm 2 ). It can be seen that the copper tube instead of the solid wire can increase the current density and save metal materials. [0003] As described in patent ZL200920092881.9, the existing insulation methods of insulating condui...
