For engineers and procurement professionals, the question “what is the best silicone insulator for high voltage” is both critical and technical. In high-voltage transmission systems, insulators must withstand extreme climates, voltage surges, and mechanical stress over long periods. This article provides a direct answer, supported by technical parameters, key performance features, and industry use cases.
The most reliable and efficient high-voltage silicone insulator today is the composite type—made of an ECR fiberglass core, liquid silicone rubber sheds, and galvanized metal fittings. These outperform porcelain and glass insulators in electrical, mechanical, and environmental durability.
Parameter | Specification |
---|---|
Rated Voltage (kV) | 35 / 66 / 110 / 220 / 500 |
Shed Material | Liquid silicone rubber, UV-resistant |
Core Rod | ECR epoxy fiberglass rod |
Tensile Strength | ≥70kN (custom up to 160kN) |
Creepage Distance | ≥1050mm (depending on rating) |
Standard | IEC 61109 / GB 19519 |
