The KYN61-40.5(Z) armored removable AC metal enclosed switchgear is a high-performance indoor power distribution solution designed for three-phase AC 50Hz systems with a rated voltage of 40.5kV. It is widely used in power plants, substations, mining operations, and industrial facilities for efficient power control, protection, and monitoring.
This switchgear plays a critical role in receiving and distributing electrical energy while ensuring system safety and operational reliability. It is especially suitable for applications requiring frequent switching operations and high-performance protection.
The KYN61-40.5(Z) switchgear is designed and manufactured in strict accordance with international and national standards, including GB/T 11022-2020, GB 3906-2020, DL 404-2020, and IEC 62271-202. These standards ensure high levels of safety, performance, and reliability in medium- and high-voltage applications.
The cabinet adopts a modular assembled structure, providing high mechanical strength and flexibility for installation and maintenance. The circuit breaker utilizes a floor-mounted withdrawable handcart design, allowing convenient operation and easy replacement.
The switchgear is equipped with a new generation of composite insulated vacuum circuit breakers, offering excellent electrical performance, long service life, and strong interchangeability between components.
A precision lead screw propulsion mechanism is integrated into the handcart system, enabling smooth movement and accurate positioning. This design effectively prevents mechanical damage caused by improper operation and enhances overall reliability.
All switching operations can be safely carried out with the cabinet door closed, significantly improving operator safety and reducing exposure to high-voltage components.
The switchgear features a compulsory mechanical interlocking system between the main switch, handcart, and cabinet structure. This system fulfills the “five prevention” requirements, including preventing misoperation such as incorrect switching, unintended energization, or unsafe access to live compartments.
The cable compartment is spacious and well-designed, allowing for the connection of multiple cables. This flexibility makes the switchgear suitable for complex power distribution systems and high-capacity installations.
Its compact footprint and robust enclosure make it ideal for indoor installations where space efficiency, safety, and durability are critical factors.
The KYN61-40.5(Z) armored switchgear is widely applied in power generation plants, transformer substations, industrial distribution systems, mining operations, and infrastructure projects. It ensures stable power supply, efficient system control, and enhanced protection for critical electrical networks.
With its advanced design, strict compliance with international standards, and reliable performance, the KYN61-40.5(Z) switchgear provides a safe and efficient solution for modern high-voltage power distribution systems. It supports long-term operation with minimal maintenance while delivering consistent and dependable performance.
