Power insulators are a key component used to support and isolate power conductors. Their main function is to ensure electrical isolation between the conductors and poles or towers, prevent current leakage, and provide the necessary mechanical strength to support the weight and tension of the conductors. Insulators play a vital role in the power system, ensuring the safety of electrical equipment and maintaining long-term stable operation under various complex environmental conditions.
Material requirements for electronic insulator working environment
The main functions of insulators are to achieve electrical insulation and mechanical fixation, and various electrical and mechanical performance requirements are stipulated for this purpose. Under the action of operating voltage, lightning overvoltage and internal overvoltage, no breakdown or surface flashover occurs; under the action of long-term and short-term mechanical loads, no destruction or damage occurs; after long-term operation under various environmental conditions such as extreme cold, extreme heat, humidity and drought, no obvious deterioration occurs;
Reasons for recommending Elaplus Materials Products
Elaplus Materials’s silicone system products cover a wide range and are involved in a wide range of fields. After self-curing, silicone has good adhesion and weather resistance, UV resistance, ozone resistance, high pressure resistance, moisture resistance, high and low temperature resistance, etc. It is resistant to leakage tracking and electrical erosion, water repellency, tear strength and hydrolysis, etc. It should be able to maintain high flexibility within the temperature range of -60-260° without causing cracks or ruptures.
