High-voltage insulators are key components of modern power systems, mainly protecting equipment from excessive electric fields, preventing insulation breakdown, and ensuring the safe operation of high-voltage machinery. Given the complexity and sensitivity of power systems, high-voltage insulator manufacturers must comply with strict standards to meet the use of power engineering.
High-voltage insulators are designed to handle the extreme conditions encountered in power transmission and distribution, which include:
- High voltage: The insulation material must withstand thousands of volts without breakdown.
- Rapid switching: The insulator must maintain its integrity during frequent voltage changes.
- 3Environmental factors: Exposure to moisture, dust, and extreme temperatures can affect the performance of insulators.
So manufacturers will perform high-voltage click tests and pull tests on their products after production to ensure that the insulators will not be damaged in extreme weather conditions.
The quality and consistency of high-voltage insulation materials are determined by the following key characteristics:
Dielectric strength (ES): The ability of the insulation material to withstand high electric fields without breakdown.
Dielectric loss ratio (ILR): A measure of the material’s ability to resist energy loss caused by polarization, indicating its purity and the absence of contaminants such as gas or moisture.
Flashover voltage (FV): The minimum voltage level that causes the insulator to spark, ensuring safe operation during switching events.
Thermal stability: Resistance to degradation at high temperatures, essential for outdoor installations.
Chemical resistance: Ability to withstand harsh environments without degradation.
Therefore, the selection of insulator materials also needs to be continuously improved. At present, our main product is composite insulators, which are lighter and more corrosion-resistant, have a longer service life, can still show excellent insulation performance in high voltage environments, and are easier to install. We believe that composite insulators are more in line with the needs and are a better choice.
High-voltage insulator manufacturers play a key role in maintaining the integrity of electrical systems.
Only reliable insulator products can reduce unexpected power outages during storms or heavy loads. At the same time, high-quality insulators can reduce energy losses and extend the service life of equipment.
Because insulators play a significant role, it is even more necessary for manufacturers of insulators to have professional qualifications and quality.
