This is the most commonly used type of disconnector in the world, thanks to the simplicity of its design, which makes it particularly cheap. Its movement, however, requires a bigger phase-to-phase spacing compared to that required for other disconnectors with the same rated voltage. Rated voltage: 36 - 550 kV Rated continuous current: up to 6300 A Rated short-time withstand current: up to 63 kA (3 s) Brochure CBD 36-52 kV Don't you see the brochure?Click here Owing to the constant development of our products, the information included in the brochure might be not fully up-to-date.
