KYN28A-12/24 Armored Withdrawable AC Metal-Enclosed Switchgear

The cabinet is made of aluminized zinc-coated steel sheets, processed and formed by CNC equipment, and assembled using bolts or rivets into a fully assembled structure.
It can be equipped with various types of vacuum circuit breakers such as VS1-24, ZN63, and VD4, to meet different application requirements.
The cable compartment is spacious, allowing for the connection of multiple cables, facilitating cable access and management.

IEC 62271: Metal-Enclosed Switchgear and Controlgear for AC Systems, 1 kV to 52 kV

GB/T 3906: Metal-Enclosed Switchgear and Controlgear for AC Systems, 3.6 kV to 40.5 kV

DL/T 404: Metal-Enclosed Switchgear and Controlgear for AC Systems, 3.6 kV to 40.5 kV

The cabinet is made from corrosion-resistant aluminum-zinc coated steel plate that requires no surface treatment. It is processed with high-precision CNC equipment and features advanced multi-fold edge technology. Connections use pull rivet nuts and high-strength bolts, resulting in high precision, lightweight, and strong structure.

The switchgear can be equipped with vacuum circuit breakers from the VS1, VD4, and ZN65 series, offering wide adaptability and strong interchangeability. The withdrawable unit (handcart) has clearly defined operating and test positions, each with positioning and indication devices to ensure safety and reliability.

The cable compartment can accommodate up to 9 single-core cables. The equipment is equipped with reliable mechanical and electrical interlock devices, fully meeting the “five prevention” safety requirements. Each compartment includes pressure relief channels to ensure operational safety for personnel.
