KYN series is a mainstream indoor metal-clad withdrawable medium-voltage switchgear widely used in global power distribution projects, especially popular in industrial, commercial and utility power systems across emerging markets. The KYN abbreviation stands for metal-clad, indoor type and withdrawable structure, with KYN28-12 as the most common 12kV model for standard power distribution scenarios.
Featuring a fully compartmentalized metal enclosure, the switchgear is divided into independent busbar, circuit breaker, cable and instrument compartments. This separated structure effectively restricts internal arc faults, enhances operational safety and simplifies daily maintenance. Equipped with a reliable five-prevention mechanical interlock system, it completely avoids common misoperations, ensuring safe working procedures for operators and power equipment.
The core advantage lies in its removable vacuum circuit breaker handcart. The faulty handcart can be quickly replaced with a spare one without cutting off the entire busbar power, greatly reducing system downtime and improving power supply stability. Made of high-quality aluminum-zinc coated steel plates, the cabinet reaches IP4X protection grade, adapting to various harsh indoor working environments.
Compliant with IEC 62271 international standards, KYN switchgear covers rated voltages from 3.6kV to 40.5kV and rated currents up to 4000A. It can be equipped with intelligent monitoring modules to meet smart grid demands. Widely applicable for power plants, substations, factories, data centers and urban infrastructure projects, it is a cost-effective and reliable medium-voltage power distribution solution for global engineering projects.
