The electric wire and cable burning tester is a precision instrument specifically designed to determine the non-propagation of flames of cables under fire conditions. This equipment is suitable for various cable types including single plastic wires, control cables, cross-linked cables, elevator cables, ship cables, and mining cables. Additionally, it can conduct vertical burning tests for high sel...
The spectrum analyzer is a high-precision instrument specifically designed for measuring the spectral characteristics of electrical signals. By converting signals into spectrum graphs, users can visually understand the signal’s spectral density and conduct in-depth signal analysis based on frequency distribution. Operating Principle At the core of a spectrum analyzer lies the principle of Fo...
Principle of Operation of the Leakage Tracer Tester The operation principle of a leakage tracer tester primarily involves insulation quality testing and leakage current testing of electrical equipment: Insulation Quality Testing: In insulation quality testing, the leakage tracer tester applies a specific voltage (often several times the rated operating voltage) to the insulation structure of the d...
Overview of Withstand Voltage Testing Withstand voltage testing evaluates the ability of various electrical devices, insulation materials, and insulation structures to withstand high voltage without compromising their insulation properties. This process involves applying a high voltage to the insulation material to assess its endurance, ensuring that the material can operate normally under working...
Overview As electrification continues to penetrate daily life, national safety standards for the electricity market have become increasingly stringent, bringing attention to the issue of leakage current. As a common problem in modern electrical systems, it is crucial to understand the differences between leakage current and stray current, as well as their respective safety issues. For engineers, i...
Overview In modern industrial production, hoses are common industrial materials widely used for liquid and gas transmission. However, prolonged use and exposure to natural environments can lead to hose aging, affecting their performance and lifespan. To evaluate the aging resistance of hoses, the xenon lamp aging test chamber has become an essential testing device. This article will discuss the pr...
Overview The salt spray test chamber is primarily used for conducting corrosion tests to ensure the quality of ferrous metals and their coatings. This test is widely used in the paint and coating industry to verify the durability and anti-corrosion properties of coatings. Corrosion significantly impacts ferrous metals, and the salt spray test chamber can simulate a saline environment to accelerate...
What is a Coating Thickness Analyzer? A coating thickness analyzer, also known as a coating thickness gauge, electroplating layer tester, or anti-corrosion layer detector, is an instrument capable of non-destructively measuring the thickness of coatings on various substrates. It can measure non-magnetic coatings (such as aluminum, chromium, copper, enamel, rubber, paint, etc.) on magnetic metal su...
Overview Ball Pressure Test (Resistance to Heat) is a critical experiment for evaluating the heat resistance performance of insulation materials, primarily used to support and protect energized components. The testing temperature varies depending on the material’s application, typically requiring materials supporting energized components to be tested at 125°C. Given that electrical accessor...
