PTFE is extremely resistant to oil, acid, alkali and strong oxidants, and is suitable for harsh working conditions such as petrochemicals, aerospace, etc. The smooth surface of PTFE reduces wear and tear, and is not prone to cracking or aging after long-term use, ensuring insulation reliability. Fluororubber (FKM) has excellent resistance to fuel, lubricating oil and ozone, preventing protection The sheath ages and cracks, and is suitable for oily environments such as automobiles and mines. Fluororubber (FKM) is soft and tear-resistant, adapting to mechanical deformation in complex terrain or frequently moving scenarios, avoiding damage to the internal structure caused by sheath damage, and fluororubber (FKM) can remain stable after long-term exposure to outdoor environments, delaying cracking and yellowing, and extending the service life of the cable. The stainless steel wire braided armor provides high tensile strength and lateral pressure resistance to prevent the internal structure from being deformed due to extrusion and impact during cable laying or use. The metal braided layer can shield external electromagnetic interference and ensure the purity of signal transmission. It is suitable for precision instrument control or communication fields. Through material innovation and structural optimization, this cable solves the problems of traditional cables that are prone to aging, insufficient mechanical strength, and signal interference under extreme temperatures. It has high reliability, long life and adaptability to multiple scenarios, providing high-performance transmission solutions for high-end industries and special fields.

At the same time, the fan-shaped groove 405 slides slowly along the limit groove 418 to achieve damping limit in the contact process. The conductive sheet 427 in the insulating box 428 pushes the fourth conductive rod 431 through the second spring 426, so that the contact block 406 is always in close contact with the surface of the resistor 420.

The insulating tube 425 and insulating housing 417 isolate the live components from the mechanical transmission structure, preventing electrical failures caused by leakage or mechanical wear.
[0020] A connecting frame 430 is fixedly connected to the side of the inner cavity of the insulating box 428 away from the third conductive rod 422.

The equipment forms a closed-loop detection system of "current gradual loading-performance parameter feedback-real-time data analysis" through precise displacement control of the electric telescopic rod 404, dynamic resistance adjustment of the resistor 420 and data collection of Test Table 3, ensuring that the cable completes multi-operating condition performance verification within a safe range. This equipment realizes smooth current regulation and multi-operating condition simulation through the coordinated design of mechanical transmission and electrical control, solving the problem of cable damage caused by current mutation in traditional detection, while improving test accuracy and efficiency. It is suitable for special cable quality detection with high reliability requirements and improves the credibility of the test results.
[0021] The working principle of the present invention is as follows: the workbench 1 starts the regulator 424, and outputs a preset basic voltage to the third conductive rod 422 through the power supply line 423. The current is conducted to the front end of the resistor 420 through the third conductive rod 422, and the electric telescopic rod 404 drives the fixed insulating frame 421 to move laterally along the tooth plate 412, so that the second conductive rod 415 is initially in contact with the wiring port of the cable body 5. At this time, the resistor 420 is in a high resistance state, allowing only a small current to pass through to avoid instantaneous overload. The moving ring 419 is connected to the push plate 414 through the third spring 416, and the sliding damping of the fan-shaped groove 405 and the limit groove 418 cooperates to form a buffering motion system. When the electric telescopic rod 404 is pushed forward, the second triangular plate 410 slides along the inclined surface of the first triangular plate 411, pushing the moving ring 419 to compress the third spring 416 backward. At the same time, the fan-shaped groove 405 slides slowly along the limit groove 418 to achieve damping limit of the contact process. The conductive sheet 427 in the insulating box 428 is connected to the push plate 414 through the second spring 426 The fourth conductive rod 431 is pushed so that the contact block 406 is always in close contact with the surface of the resistor 420. As the electric telescopic rod 404 continues to move forward, the movable ring 419 drives the insulating shell 417 to move backward, and the distance between the resistor 420 and the second conductive rod 415 gradually decreases. The effective resistance of the resistor connected to the circuit gradually decreases, and the current increases linearly. The relative displacement of the resistor 420 and the contact block 406 is controlled by the stroke of the electric telescopic rod 404. In the initial stage, the resistance value is large and the current is small. As the contact block 406 slides toward the end of the resistor, the effective resistance decreases, and the current gradually increases to the full load state, simulating the performance of the cable under different loads. Test Table 3 simultaneously collects current data, and the control system of the workbench 1 records the voltage, temperature and mechanical stress changes of the cable under the gradient current to evaluate its high and low temperature resistance, aging resistance and toughness. The third spring 416 works in conjunction with the sliding damper to ensure that the contact process between the contact block 406 and the resistor 420 is impact-free, avoiding instantaneous short circuit or arc generation. Even if the output of the regulator 424 is abnormal, the spring can adaptively compress to absorb excess energy. The insulating tube 425 and the insulating shell 417 isolate the live parts from the mechanical transmission structure to prevent electrical faults caused by leakage or mechanical wear. The equipment forms a closed-loop detection system of "current gradual loading-performance parameter feedback-real-time data analysis" through precise displacement control of the electric telescopic rod 404, dynamic resistance adjustment of the resistor 420 and data collection of Test Table 3, ensuring that the cable completes multi-operating condition performance verification within a safe range. Through the coordinated design of mechanical transmission and electrical control, this equipment realizes smooth current regulation and multi-operating condition simulation, solving the problem of cable damage caused by current mutation in traditional detection, while improving test accuracy and efficiency. It is suitable for special cable quality detection with high reliability requirements and improves the credibility of the test results.
