Description

technical field [0001] The invention relates to a device for testing electrical conductivity, tensile strength and aging, in particular to a comprehensive testing device for electrical conductivity, tensile strength and aging of electric wires and cables. Background technique [0002] Wires and cables are widely used in various living and production places. Due to its many supply channels, the product quality varies greatly. For example, in order to reduce costs, the copper material is artificially shrunk to reduce the cross-sectional area, or the recycled copper with high impurities is used to produce products with seriously exceeded resistance. In addition to the loss of current passing through the line, the heating is aggravated. For the bare wires used in overhead high-voltage lines, the consequences are increased line loss and complicated harmonic transmission; and for cables with insulating sheaths, it will not only increase the line loss and use Harmonic transmission...

Problems solved by technology

To obtain a large number of measurement data, it is necessary to continuously place the samples on different test benches, and the data cannot be automatically collected, converted, recorded and saved, and there is a high possibility of errors caused by human factors
