DX8398 Conductor Tensile or Elongation Testing Machine

The DX8398 Conductor Tensile Strength & Elongation Tester is a specialized testing instrument designed to evaluate the mechanical properties of various metal conductors, copper wires, and aluminum wires, serving as a core piece of equipment for quality control, research and development, and incoming inspection in the wire and cable manufacturing, metal material processing, and electrical component industries. It is engineered to deliver accurate, reliable, and efficient testing solutions for conductor performance verification, meeting the diverse and stringent testing requirements of modern manufacturing standards.

Application Scope

This tester is specifically developed for testing a wide range of metal conductors, including bare copper wires, aluminum wires, copper-clad aluminum wires, alloy conductors, and other metallic wires used in power cables, communication cables, automotive wiring harnesses, electronic components, and electrical equipment. It is capable of conducting multiple key mechanical performance tests on conductor specimens, covering four primary test items as follows:

1. Tensile Strength Test: To determine the maximum tensile force that a conductor can withstand before breaking, which is a critical indicator of the conductor’s load-bearing capacity and structural integrity.

2. Elongation Test: To measure the percentage change in length of the conductor specimen after it is subjected to tensile force until fracture, which reflects the ductility and flexibility of the material, a key parameter for evaluating the conductor’s resistance to deformation during installation and service.

3. Bending Resistance Test: To assess the conductor’s ability to withstand repeated bending stress, simulating the mechanical fatigue conditions that the conductor may encounter during manufacturing, installation, or long-term use, ensuring the conductor does not break or crack under cyclic bending loads.

4. Fatigue Resistance Test: To evaluate the conductor’s durability under repeated mechanical stress, verifying its ability to maintain structural stability and electrical performance after prolonged cyclic loading, which is essential for ensuring the long-term reliability of wires and cables in various application scenarios.

The tester is widely applicable in multiple industrial scenarios, including factory quality inspection for wire and cable manufacturers, incoming material inspection for electronic and automotive component suppliers, laboratory research and performance verification for new conductor material development, and third-party testing institutions’ compliance testing for industry standards. It can adapt to different conductor specifications, from fine gauge wires used in electronic components to large-diameter conductors for power transmission cables, making it a versatile solution for conductor mechanical performance testing across the supply chain.

Key Parameters

The DX8398 tester is equipped with precise and flexible parameter configurations to meet the diverse testing needs of different conductor materials and specifications, with core parameters as follows:

1. Measuring Range: The tester offers optional measuring ranges from 10kg to 100kg, allowing users to select the appropriate range based on the expected tensile strength of the test specimens. This modular design ensures that the tester can handle both low-strength fine wires and high-strength large-diameter conductors, eliminating the need for multiple specialized testing instruments and reducing procurement costs.

2. Force Resolution: With a high force resolution of 0.01kg, the tester can capture even minor changes in tensile force during the testing process, ensuring that the collected data is highly accurate and reliable. This level of precision is critical for meeting the strict data accuracy requirements of industry standards and providing trustworthy test results for quality control and R&D purposes.

3. Maximum Stroke (Excluding Grips): The tester provides three optional maximum stroke specifications: 150mm, 250mm, and 500mm. This flexible stroke configuration allows users to test specimens of different lengths, from short standard test samples to longer conductors that require extended testing ranges, ensuring compatibility with various test methods and specimen preparation requirements.

4. Display System: The tester is equipped with a 15mm×85mm digital tube display, which presents test data clearly and directly in real time. The large, high-visibility digital readout ensures that operators can easily read and record test results without the need for complex data interpretation or secondary calculations, reducing the risk of human error and improving testing efficiency.

5. Core Functional Features:

- Peak Tensile Force Lock: The tester features a peak tensile force locking function, which automatically captures and holds the maximum tensile force value reached during the test. This eliminates the need for operators to manually monitor and record peak values, ensuring that the critical maximum load data is accurately captured even in fast-paced testing environments.

- Direct Elongation Readout: Elongation values can be displayed directly on the digital tube, eliminating the need for manual calculation of elongation percentage based on initial and final specimen lengths. This direct readout feature streamlines the testing process, reduces testing time, and minimizes the potential for calculation errors, making the tester highly efficient for high-volume production testing scenarios.

6. Drive System: The tester is powered by an AC motor drive system, which delivers stable, consistent power output throughout the testing process. The AC motor ensures smooth operation with low noise, minimal vibration, and reliable performance, even during prolonged continuous testing operations. This robust drive system is designed for long-term use in industrial environments, reducing maintenance requirements and ensuring consistent test results over the equipment’s service life.

Core Advantages

The DX8398 Conductor Tensile Strength & Elongation Tester stands out in the market due to its combination of high precision, versatility, ease of use, and durability, offering several key advantages for users in the wire and cable and metal material industries:

1. High Precision and Accuracy: The tester’s 0.01kg force resolution ensures that test data is collected with exceptional precision, meeting the strict accuracy requirements of national and international industry standards. The high-resolution data acquisition system eliminates measurement errors caused by low-precision sensors, providing reliable test results that can be used for quality certification, compliance testing, and R&D validation.

2. Multi-Functional Testing Capability: Unlike single-function testing instruments, the DX8398 tester integrates multiple mechanica
