High Voltage Complete Switchgear
The KYN28‑12 is a high‑performance, highly reliable medium‑voltage withdrawable metal‑enclosed switchgear, designed for three‑phase AC systems with a frequency of 50 Hz and a rated voltage of 12 kV. It is used to receive and distribute electrical energy, as well as to provide circuit control, protection, and monitoring. Our company’s KYN28‑12 indoor AC metal‑enclosed withdrawable switchgear represents an advanced‑technology medium‑voltage switchgear system, suitable for a wide range of power generation, distribution, and utilization applications, including main and auxiliary power panels, distribution cabinets, motor‑power supply and motor control centers, power systems, petrochemical facilities, ships, oil‑rig platforms, industrial and mining enterprises, public utilities, municipal projects, and commercial buildings. It complies with the Chinese national standards GB/T 11022 “Common Technical Requirements for High‑Voltage Switchgear and Control Equipment,” GB/T 3906 “AC Metal‑Enclosed Switchgear and Control Equipment Rated 3.6–40.5 kV,” GB/T 4208 “Degrees of Protection Provided by Enclosures,” and DL/T 404 “Technical Specifications for Ordering Indoor AC High‑Voltage Switchgear.”
The KYN61-40.5 AC metal-clad withdrawable switchgear is a 40.5 kV, three-phase, 50 Hz indoor complete distribution device designed for power reception and distribution in power plants, substations, and industrial and mining enterprises. It provides circuit control, protection, and monitoring functions and is suitable for applications involving frequent operations. The entire cabinet employs air insulation and is equipped with fully insulated vacuum circuit breakers. With its highly adaptable structure and versatile wiring configurations, the product offers reliable “five-protection” features, making it an advanced‑technology, stable‑performance, reasonably structured, user‑friendly, and safe, compact distribution device. Our company’s KYN61-40.5 AC metal-clad withdrawable switchgear represents a high‑voltage switchgear system of cutting‑edge technological standards, applicable to all power generation, transmission, distribution, and utilization settings, including large thermal, combined heat and power, and nuclear power plants; hydropower stations; wind farms; solar power plants; airports; schools; ships; oil drilling platforms; industrial and mining enterprises; public utilities; municipal projects; and commercial buildings. It complies with GB 11022 “Common Technical Requirements for High-Voltage Switchgear and Control Equipment,” GBT 3906 “3.6–40.5 kV AC Metal-Enclosed Switchgear and Control Equipment,” GBT 4208 “Degrees of Protection Provided by Enclosures,” and DL/T 404 “Technical Specifications for Ordering Indoor AC High-Voltage Switchgear.”
XGN‑12(F) and XGN‑12(F.R) box-type, fixed‑type, metal‑enclosed SF6 ring‑main switchgear are designed for ring‑network or radial power supply systems with a rated voltage of 12 kV and a rated current of 630 A or less. They are particularly well suited for installation in prefabricated substations, serving as control and protection devices within the power system. This product features a compact footprint, light weight, simple operation, low operating force, reliable interlocking, and virtually maintenance‑free operation. Our company’s XGN‑15‑12 series is widely used in urban distribution stations for ring‑network construction and city‑grid upgrades, as well as in power distribution applications at industrial and mining enterprises, high‑rise buildings, residential communities, sports facilities, and other locations—such as main and auxiliary power cabinets, distribution panels, motor‑power supply systems, motor control centers, and in sectors including power generation, petrochemicals, marine vessels, oil‑drilling platforms, industrial and mining operations, public utilities, municipal engineering, and commercial buildings. The equipment complies with standards such as GB/T 3906 and GB/T 3804.
