KYN28-12 Metal-Clad HV Switchgear

Product Overview

The KYN28-12 Metal-Clad Removable High-Voltage Switchgear is suitable for three-phase AC 50Hz/60Hz, 12kV power systems. It is primarily used for power plants, industrial and mining enterprises, public utility distribution substations, and high-voltage motor control systems. The switchgear features an armored layout, divided into independent functional compartments to maximize safety and limit damage in the event of an internal arc.

Key Features

• Metal-Clad Compartmentalized Construction: Fully enclosed by metal plates with dedicated pressure relief channels for the circuit breaker, busbar, cable, and instrument compartments.
• Removable Handcart Circuit Breaker: Utilizes highly reliable vacuum circuit breakers (such as VD4, VS1) mounted on a robust, smooth-rolling handcart.
• Five-Anti Mechanical Interlock: Integrates rigorous mechanical and electrical interlocks to prevent all common operator errors.
• Spacious Cable Connection Area: Roomy cable compartment accommodates multiple cable connections and surge arrestors, allowing easy bottom cable entry.
• Excellent Environmental Adaptation: High-quality Al-Zn coated steel sheets provide outstanding corrosion and oxidation resistance.
