The KYN28-12 high voltage switchgear uses the VS1 (ZN63) type vacuum circuit breaker with high breaking capacity and low short-circuit making capacity as the main switch. It features an advanced, rational, and compact structure, excellent performance, and high reliability. It also includes a “five protections” interlocking function, meeting the technical standards of IEC 298, GB 3906, and other relevant standards.

Features: The KYN28-12 high voltage switchgear has an advanced and rational structure.

Cabinet Parameters:

• The cabinet structure is made from aluminum-zinc coated sheet metal processed by CNC machines with multiple bending techniques and bolted together.
• All operations are performed with the cabinet door closed.
• High protection grade, preventing debris and pests from entering.
• Simple and effective “five protections” interlocking mechanism to prevent incorrect operations.
• Compatible with VS1 and VD4 type vacuum circuit breakers.
• Simple breaker replacement with good truck interchangeability.
• The cabinet is reliably wall-mounted, with front access for maintenance, reducing floor space usage.
• Spacious cable compartment, allowing for the connection of multiple cables.
• Both the circuit breaker and cable compartments can be equipped with heaters to prevent condensation and corrosion.
