KYN61-40.5 Type Armored Withdrawable AC Metal-Enclosed Switchgear

The KYN61-40.5 type armored withdrawable AC metal-clad switchgear is characterized by the use of a fully insulated vacuum circuit breaker of model ZN85-40.5 and a spring-operated mechanism within the cabinet. It can also be equipped with ABB’s VD4-40.5 and HD4-40.5 switchgear units. The cabinets are assembled from aluminized-zinc coated sheets and cold-rolled steel plates with powder-coating, which enhances the precision of the coordination between the handcart and the cabinet. The handcart can be pushed in and pulled out with remarkable ease and exhibits excellent interchangeability. The equipment features an aesthetically pleasing appearance, a comprehensive range of configurations, and ensures safe and reliable operation.

Introduction

Product Overview

　　The KYN61-40.5 type armored withdrawable AC metal-clad switchgear is characterized by the use of a fully insulated vacuum circuit breaker of model ZN85-40.5 and a spring-operated mechanism within the cabinet. It can also be equipped with ABB’s VD4-40.5 and HD4-40.5 switchgear units. The switchgear enclosure is assembled from aluminized-zinc coated steel sheets and cold-rolled steel plates with powder-coating, which enhances the precision of the coordination between the handcart and the cabinet. As a result, pushing in and pulling out the handcart is remarkably smooth and effortless, and the handcarts are highly interchangeable. The equipment features an aesthetically pleasing appearance, a comprehensive range of configurations, and ensures safe and reliable operation.

　　This product is designed for use in 35kV three-phase AC 50Hz power systems, serving as a device for receiving and distributing electrical energy in substations, power plants, and distribution rooms of industrial and mining enterprises. It features functions such as control, protection, and monitoring.

　　This product complies with the following standards: GB3906 “AC Metal-Enclosed Switchgear Rated from 3 to 35 kV,” GB/T 19992 “Common Technical Requirements for High-Voltage Switchgear and Control Equipment,” DL/T404 “Technical Specifications for Ordering AC High-Voltage Switchgear,” and IEC60298 “AC Metal-Enclosed Switchgear and Control Equipment Rated from 1 kV to 52 kV.”
