Import Cut Out Switch (Cos) — Buy in Bulk from Supplier in South Korea (Republic Of Korea)

The Cut Out Switch (COS) from Guju Technology, Inc. is a high-voltage isolation device designed for use in medium-voltage distribution networks, with a rated voltage section length leakage distance of 25.8 kV. It is constructed with ceramic insulators and corrosion-resistant metal components to withstand outdoor exposure and environmental stress. The switch operates as a manual disconnect under no-load conditions, complying with IEC 62271-102 standards for switching devices in high-voltage systems.

This switch features a water-repelling housing and impact-resistant polymer casing, typical of industrial-grade COS units used in humid or coastal regions. The internal arcing chamber is engineered to suppress electric arcs during disconnection, reducing maintenance needs. Standard variants include single-pole and three-pole configurations, with optional grounding blades for enhanced safety. Material composition follows typical industry norms for dielectric strength and thermal stability, with no plasticizers or volatile compounds that degrade under prolonged UV exposure.

The device is commonly sourced by utility providers, renewable energy installers, and industrial plant operators in Asia and the Middle East for transformer protection and feeder isolation. Buyers typically require certification of dielectric testing and mechanical endurance cycles. Packaging is in wooden crates with foam inserts to prevent vibration damage during transit. Trade terms are commonly FOB Busan or CIF port of destination, with lead times of 4 to 6 weeks after order confirmation.
