Based on your question and industry standards and practices, the wire and cable industry mainly requires the following types of core testing equipment for mechanical performance testing,To meet the testing requirements of various stretching, compression, bending, etc. from raw materials to finished cables.

1.Electronic universal material testing machine (core equipment)

This is the most commonly used and basic testing equipment in the wire and cable industry, also known as the universal tensile testing machine. It is controlled by a computer, with high precision and versatility, and is an instrument that completes most standard tests.

-Main function: Used to test key parameters such as tensile strength, elongation at break, yield strength, elastic modulus, etc. of wires and cables and their raw materials (such as metal wires, plastics, rubber sheaths). By adding different attachments, compression, bending, shear, peel, tear and other tests can also be conducted.

Technical characteristics:

-High precision measurement: Imported servo motors, ball screws, and high-precision sensors are usually used to ensure that the measurement accuracy of the test force can reach ± 1% of the indicated value1%Or higher.

-Wide range speed regulation: The test speed can be within0.001～1000mm/minStepless speed regulation within the range to meet the requirements of different materials and standards.

-Intelligent system: equipped withWindowsOperating platform, software supports multiple languages, real-time curve display, automatic data processing, and report generation.

-Compliant with standards: Designed to meetGB/T16491(Electronic universal testing machine)GB/T228(metal material stretching) andASTMD638TheISO37Waiting for a large number of international and domestic standards.

2.Horizontal tensile testing machine (for large-sized samples)

When testing the overall tensile performance of products such as large-sized wires and cables, steel wire ropes, and cables, vertical testing machines are limited by height and require the use of specialized horizontal tensile testing machines.

-Core advantage: Its characteristic is having an ultra long effective stretching space. For example, some models have an effective stretching space that can reach32Meter, effective width up to900mmCan meet the testing requirements of long cables under real working conditions.

-Application scenario: Especially suitable for tensile performance testing of large-sized products such as power industry, bridge cables, and marine engineering cables.

3.Special fixtures and measuring accessories

The functionality of a tensile testing machine is highly dependent on the matching fixtures and measuring devices. For the wire and cable industry, the following categories are particularly important:

-Special stretching fixture: It is required to be equipped with circular wires suitable for clamping different diameters (such as Φ)10～Φ70mm）Fixtures for flat wires or finished cables to ensure that they do not slip or damage the specimen during the testing process.

-Deformation measurement device:

-Electronic extensometer: used to accurately measure the small deformation of the specimen during the tensile process, it is the key to calculating parameters such as elastic modulus and specifying non proportional tensile strength.

-Large deformation extensometer: suitable for testing insulation or sheath materials with high elongation such as rubber and plastic.
