Description

Technical Field

[0001] The utility model belongs to the technical field of cable tension test equipment design, in particular to a multifunctional tension test equipment. Background Art

[0002] Cable is a collection of wires used to transmit electricity, communication signals or data. According to different uses, cables can be divided into power cables, communication cables, fiber optic cables and other types. Power cables are mainly used to transmit electricity, communication cables are used to transmit telephone and network signals, and fiber optic cables are used to transmit optical signals. Cables are usually composed of components such as conductors, insulation layers, and sheaths. The structure of cables for different purposes will also vary. The quality and structure of cables are crucial to the quality of signal transmission. The tension of cables refers to the tensile force or tension to which the cables are subjected during use. When designing cables, the maximum tension that needs to be borne is usually taken into account to ensure that the cables will not be broken or damaged under normal use conditions. For different types of cables, the design tension will be different. For example, power cables, communication cables and fiber optic cables, etc., the tolerable tension range will be determined according to the specific use and environmental requirements during the design stage.

[0003] Before existing cables are produced and shipped out of the factory, they need to be sampled and tested for tensile strength to check whether they meet the usage standards. In the existing testing process, the cables are mostly tested by pulling them in a straight line. When the cables are under tension, they may be in a twisted state. At the same time, different operating temperatures will also affect the cable's ability to withstand tension. The existing testing equipment lacks simulation of actual usage conditions, and the test authenticity is low. Utility Model Content
