KYN28 Out Door High Voltage Electrical Switchgear Cabinet for Safety Power Supply System
Application:
The KYN28-24/1250-31.5 indoor metal-clad withdrawable switchgear is suitable for AC 50Hz, 3~24kV power systems and is widely used in power plants, substations, switching stations, urban power distribution, industrial and mining enterprises, shopping malls, airports, subways, wind power generation, hospitals, stadiums, railways, tunnels, and other places for control, protection, and monitoring. It can be equipped with either a standard switchgear or a domestically produced VS1 vacuum circuit breaker, making it a high-performance power distribution device with advantages such as flexible scheme combinations, compact structure, safety and reliability, convenient maintenance, impact resistance, and corrosion resistance.
Product Features:
All-metal assembly, modular assembly structure;
The cabinet is made of imported aluminum-zinc coated thin steel sheet, processed by the FMS flexible processing system, and uses advanced multi-folding technology. It is connected with rivet nuts and high-strength bolts, resulting in high precision, corrosion resistance, light weight, high strength, and strong versatility.
The handcart is equipped with working and testing devices, and each position has a positioning and display device, ensuring safety and reliability.
Carts of the same specification are freely interchangeable, offering high interchangeability;
The handcart is transported by a dedicated transport vehicle, making operation easy and flexible;
The cable compartment can accommodate up to nine single-core cables;
Reliable mechanical and electrical interlocking devices fully meet the "five-proof" requirements;
High-voltage compartments all have pressure relief channels to ensure personal safety;
The front door is equipped with an observation window to observe the working status of the components inside.
