Abstract

An electric wire and cable conductivity, tensile strength and aging comprehensive testing device comprises a testing control system, an analytical balance, an electrical bridge with a clamp, an insulation resistance tester, a tension testing machine, a high-temperature low-temperature humidity thermal cycling testing machine, an air-exchange aging testing machine, an ozone-proof aging testing machine, an xenon lamp weather-proof testing machine, a gas analysis device and a test control system. The device can test mechanical performance of an electric wire and cable, electric performance of the electric wire and cable and performance of the electric wire and cable under the influence of environment at a time, can effectively reduce work load of a test of the electric wire and cable, enables the test of the mechanical performance, the electricity performance, and the performance of the electric wire and cable under the influence of the environment to be concentrated and effective, and can synchronously test components of released gases of a cable with a sheath in the aging process.

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...
