Wholesale 36kv Kyn28A-12 AC Metal Enclosed Distribution Cabinet for Solar Photovoltaic

Product Description

Product Description

The KYN28A-12 is an advanced indoor switchgear designed for AC systems ranging from 3.6kV to 12kV at 50/60Hz. It is well-suited for applications in industries, mining, power plants, and substations, and it accommodates single bus configurations, which improve control, protection, and monitoring within medium voltage networks. Crucial for power transmission and distribution, it plays a vital role in electrical infrastructure.

Product Features	Enhanced Safety Measures	Complying with international standards such as  IEC60298 , the KYN28 switchgear incorporates advanced safety features. These include mechanisms to prevent accidental operations such as the misoperation of the circuit breaker's handcart under load, inadvertent closing or opening of the circuit breaker, engagement of the circuit breaker with the grounding switch activated, unauthorized access to energized compartments, and incorrect operation of the energized grounding switch.
	Broad Compatibility	This switchgear is designed to be compatible with a wide range of vacuum circuit breakers, from domestic models like the VCA and VS1 to globally recognized brands such as VD4-I2 and  EV 12S. This versatility ensures it can meet the diverse needs of customers across various sectors.
	Intelligent Control	Equipped to host several microprocessor-based relay protection devices, the KYN28 enables seamless integration with fieldbus control networks through the CAN communication interface. This facilitates sophisticated control functions, including remote control, telemetry, remote signaling, and remote adjustments, streamlining system management and enhancing operational efficiency.
	Compact Design and Easy Maintenance	Constructed from premium materials and utilizing state-of-the-art CNC machining, the switchgear boasts a compact and robust design that simplifies installation and maintenance. Its handcart components are modular, allowing for easy replacements and upgrades which contribute to lower maintenance costs.
	Superior Isolation and Cooling	Featuring a design that isolates different functional compartments, the switchgear ensures enhanced safety and reliability. It is also equipped with dedicated pressure relief channels and an effective cooling system, guaranteeing consistent performance even under prolonged operational periods.
