KYN28-12/24 High Voltage Switchgear, Indoor Metal-Clad Withdrawable AC Enclosure, Rated Voltage 12/24kV

Product Description

1. Product Overview

The JRH KYN28-12/24 Indoor Metal-Clad Withdrawable Switchgear is a highly reliable, complete indoor power distribution device designed for 3-phase AC 50 Hz single-bus or double-bus sectionalized systems. Engineered to receive and distribute network power while providing essential control, protection, and monitoring, this switchgear is the backbone of modern electrical infrastructure. It is widely applied in power plants, substations, industrial and mining enterprises, and high-rise building power systems, seamlessly supporting microcomputer protection and remote grid monitoring.

2. Key Features & Selling Points

• Ultimate “Five Preventions” Safety Interlock: Features a robust mechanical and electrical interlocking system that prevents circuit breaker misoperation, pushing/pulling the handcart under load, closing the grounding switch when energized, transmitting power when grounded, and accidental entry into live compartments.

• Versatile Circuit Breaker Compatibility: Flexible design allows for the installation of premium imported vacuum circuit breakers (VCB) or high-performance domestic VS1 VCBs, catering to diverse project budgets and technical preferences.

• Smart Grid & Microcomputer Ready: Readily accepts comprehensive control protectors and supports computer networking, enabling real-time microcomputer protection, telemetry, and automated substation monitoring.

• Metal-Clad Compartmentalization: The enclosure is fully armored and divided into independent compartments (busbar, breaker, cable, and low-voltage), preventing fault propagation and ensuring maximum operator safety.

• Withdrawable Handcart Design: The breaker handcart offers precise positioning and easy interchangeability, drastically reducing maintenance downtime and ensuring rapid power restoration.
