What type of insulation is used in high-voltage applications?

In high-voltage applications, cross-linked polyethylene (XLPE) and ethylene propylene rubber (EPR) are preferred materials for insulation due to their excellent electrical and thermal properties. XLPE is known for its outstanding resistance to heat, chemicals, and environmental stress, which makes it particularly suitable for the harsh conditions often encountered in high-voltage scenarios. EPR also provides good electrical insulation and flexibility, making it effective in high-voltage environments where maintaining reliable performance over time is crucial.

These materials not only resist electrical breakdown under high-voltage conditions but also offer durability and longevity, ensuring that they can withstand the operational demands placed on them. Additionally, they are designed to handle the thermal effects that can arise from continuous high-voltage operation, which contributes to safer and more efficient energy transmission.

While other insulation materials like polyvinyl chloride (PVC), fiberglass, and rubber have their own applications, they do not provide the same level of performance and reliability as XLPE or EPR in high-voltage systems, which require materials capable of withstanding stringent conditions.
