Composite insulators

Insulators are used in electrical equipment to support and separate electrical conductors without allowing current to pass through the insulators. Silicone rubber is the most widely used polymeric insulation material for high voltage products. Our composite insulators have excellent performance in all climates and harsh conditions such as coastal, desert and industrial environments.

Composite insulators with silicone rubber insulation possess unique properties and are installed all over the world. Hitachi Energy offers a wide range of insulators, and together with our flexible production method can deliver composite insulators that will meet your requirements.
