In the field of electrical connection, the pre-insulated material of double crimping hook-shaped pre-insulated terminal plays a vital role and has many special features.
First of all, this pre-insulated material has excellent insulation performance. It usually uses high-performance engineering plastics such as polyamide (nylon) or polyvinyl chloride (PVC) and is specially formulated and optimized. Its insulation resistance is extremely high, which can effectively prevent current leakage and provide reliable insulation protection for electrical connections at various voltage levels. For example, in the terminal connection of high-voltage power transmission lines, pre-insulated materials can withstand voltages of thousands of volts or even higher, preventing dangerous situations such as leakage and short circuit caused by insulation failure, ensuring the safe and stable operation of the power system and the personal safety of operators.
Secondly, pre-insulated materials have good temperature resistance. Whether it is continuous work in a high temperature environment or short exposure in low temperature conditions, it can maintain stable performance. In some industrial application scenarios, such as near the heat sink of electronic equipment or in high-temperature workshops, pre-insulated materials can withstand temperatures up to 100°C or even higher, and will not soften, deform or lose insulation properties due to high temperatures. In cold outdoor environments, such as power facilities in northern winter, even if the temperature drops to dozens of degrees below zero, it still maintains sufficient toughness and insulation effect, and will not become brittle and crack, thus ensuring the reliable use of terminals under different climatic conditions.
Furthermore, the pre-insulated material has excellent chemical corrosion resistance. In harsh environments such as chemical production and electroplating workshops where there are various strong acids, strong alkalis and organic solvents, it can resist the erosion of chemical substances. Its special chemical structure makes it difficult to react chemically with acids, alkalis, salts, etc., and will not cause insulation performance degradation or material damage due to chemical corrosion. For example, when using a double crimping hook-shaped pre-insulated terminal at the electrical connection of a chemical pipeline, the pre-insulated material can effectively prevent damage to the terminal insulation layer caused by chemical leakage, ensuring the long-term stability of the electrical connection.
In addition, the pre-insulated material has strong adhesion to the metal part of the terminal and the wire. It can be tightly wrapped around the surface of the metal terminal and the outer layer of the wire to form a seamless insulation barrier. This tight fit not only further enhances the insulation effect, but also effectively prevents the insulation layer from peeling off or loosening due to external force or long-term use. During the vibration, impact or frequent plugging and unplugging of the equipment, the pre-insulating material can always be firmly attached to the terminal, maintaining its insulation performance, and providing a strong guarantee for the reliability of the electrical connection.
