KYN61-40.5 AC Metal-Enclosed Switchgear

Product Advantages

KYN61-40.5 AC Metal-Enclosed Switchgear 40.5kV High Voltage Rating: Adapted for 35kV Power Grids. With a rated voltage reaching 40.5kV, this equipment is perfectly tailored for domestic 35kV power grids. Compared to standard 24kV central-cabinet switchgear, it is capable of withstanding higher voltages, thereby fully meeting the power distribution requirements of 35kV networks.

Larger Cabinet, Enhanced Insulation Protection: The enlarged cabinet structure—combined with insulation safeguards specifically designed for 35kV systems—enables the equipment to safely handle high 35kV voltages. The increased insulation clearance effectively prevents high-voltage breakdown, ensuring the stable and reliable operation of the high-voltage system.

IP5X Ultra-High Protection: The enclosure boasts an IP5X protection rating—superior to that of standard 24kV central-cabinet switchgear. This rating ensures effective resistance against dust and moisture ingress, allowing the equipment to operate stably and reliably even in environments characterized by high humidity or heavy dust, thereby safeguarding the internal high-voltage components.

"Five-Prevention" Interlocking: Ultimate Safety. Featuring a dedicated "Five-Prevention" interlocking system, this equipment completely eliminates the risk of operational errors. It prevents the accidental opening or closing of circuit breakers; prohibits the operation of disconnectors under load; prevents the application of ground wires to live circuits; prohibits the closing of circuit breakers while ground wires are connected; and prevents accidental entry into live compartments. This ultimate level of safety protection ensures the operational safety of 35kV high-voltage systems.
