The invention aims at providing a test apparatus for flexibility of a low-smoke halogen-free electric wire. One end of an electric wire is connected to a left electric wire electrification connecting box in a box body, then the electric wire successively passes through a fixed ring, a guiding ring, a guiding wheel, a first winding wheel and a second winding wheel at the left side and through a guiding wheel, a guiding ring and a fixed ring at the right side, finally the other end of the electric wire is connected to a right side electric wire electrification connecting box in the box body, after the connection, the electric wire is electrified, and an installation plate is driven by a sliding drive motor to slide left and right, so that the electric wire is bent and stretched, and after the electric wire is bent and stretched for a given times or is broken, the flexibility performance of the electric wire is assessed; and moreover, two ends of the electric wire are respectively provided with a weight load. The flexibility of the electric wire can be well tested, and the test apparatus is suitable for the test.
Description
technical field [0001] The invention relates to the testing field of low-smoke and halogen-free electric wires, in particular to a meandering test device for low-smoke and halogen-free electric wires. Background technique [0002] Our company mainly produces wires and plugs. First, the raw materials of the wires are produced, and then the raw materials and twisted copper wires are extruded together to form the wires. This type of plug wire is used in products such as air conditioners. At present, there are more and more fires caused by the aging of wires and cables. How to reduce the incidence of fire and the death rate in the event of fire, low smoke, halogen-free, flame retardant, and environmental protection have also become the development direction of the wire and cable industry. . Therefore need electric wire to have good winding performance, but the device effect to electric wire winding performance test is not very good in production. Therefore, it is necessary to...
