Problems solved by technology

Domestic metal-clad cables have cladding thickness that does not meet the standard requirements, especially the average aluminum layer thickness of aluminum-clad steel wires cannot meet the national standards and the national grid enterprise standards, and there is no cause for aluminum cladding. Steel industry attaches great importance to
At present, the industry only considers the diameter of the cladding rod and steel core in terms of electrical conductivity. The disadvantage of this design method is that it meets the electrical conductivity, but cannot meet the requirements of the average aluminum layer thickness.

Abstract

The invention relates to the technical field of structure design for aluminum-clad steel wires, and specifically relates to a thickness design method for a cable coating layer, and a thickness design method for an aluminum-clad-steel-wire aluminum layer. The theoretical value of the thickness of the coating layer in a coated cable can be obtained by utilizing the principle that the steel ratio in a coating rod is equal to the steel ratio in the coated cable so as to serve as a reference for setting the average thickness of the coating layer. According to the design method for the average thickness of the coating layer of the coated cable provided with the metal coating layer, the design value of the thickness of the coating layer is provided theoretically, the coated cable can reach and exceed the national (industrial) standard after being drawn from the coating rod, and the production quality of the coated cable is improved. Especially in production for an aluminum-clad steel wire, the average aluminum layer thickness of the aluminum-clad steel wire is obtained after drawing through design calculation for the coating rod, so that the production quality for the aluminum-clad steel wire can be improved.

Description

technical field [0001] The invention relates to the technical field of structural design of aluminum-clad steel wires, in particular to a method for designing the thickness of a cable covering layer and a method for designing the thickness of an aluminum layer of an aluminum-clad steel wire. Background technique [0002] The current national standard GB / T17937-2009 only proposes a value for the average thickness of the aluminum layer, and does not serve as a mandatory technical index requirement. Domestic metal-clad cables have cladding thickness that does not meet the standard requirements, especially the average aluminum layer thickness of aluminum-clad steel wires cannot meet the national standards and the national grid enterprise standards, and there is no cause for aluminum cladding. attention of the steel industry. At present, the industry only designs the diameters of clad rods and steel cores from the perspective of electrical conductivity. The disadvantage of this ...
