The KYN28 Medium Voltage Drawer Type Panel delivers comprehensive medium-voltage distribution capabilities, encompassing power intake, feeder dispatch, voltage surveillance, energy metering, bus segmentation, and circuit isolation. Usune supplies this equipment through a highly engineering-driven customization process, backed by ISO 9001, ISO 14001, and ISO 45001 certified management systems. All products are developed in accordance with relevant IEC and GB benchmarks, with CE certification accessible for qualifying markets. In large-scale electrical undertakings, multiple autonomous circuits—such as transformer feeds, motor lines, and auxiliary loads—often coexist rather than relying on a solitary distribution path. This arrangement enables each distinct electrical function to occupy its own dedicated cabinet within a harmonized assembly, empowering engineers to construct the distribution network directly from the project's single-line schematic instead of applying repetitive, uniform cabinet setups. This modular philosophy streamlines specification work for procurement specialists, as cabinet roles can be precisely mapped to the existing grid, while the complete formation can be dimensioned around feeder quantities, amperage demands, protective device layouts, and prospective capacity growth.
Medium-voltage switchgear arrangements are intrinsically tied to the purpose of each individual circuit, with incoming lines drawing energy from upper-level sources and outgoing lines channeling power to transformers, motors, or industrial machinery. The Medium Voltage Drawer Type Panel accommodates this reality through a circuit-centric philosophy, offering incoming cabinets, outgoing cabinets, PT/voltage monitoring cabinets, metering cabinets, bus sectionalizer cabinets, and isolation cabinets that integrate seamlessly into the broader lineup per the project's electrical blueprint. This approach is indispensable for EPC ventures, where switchgear parameters must mirror sanctioned electrical drawings with exactitude. Moreover, the modular composition of the KYN28 series furnishes enhanced adaptability for managing diverse circuits as operational demands shift. During the design phase, clients can earmark positions or stipulate supplementary functional cabinets aligned with forecasted future requirements, ensuring the switchgear evolves from a mere standalone apparatus into a foundational element of the facility's enduring electrical infrastructure.
Spatial planning for electrical rooms demands equipment that balances service accessibility with spatial efficiency. The Medium Voltage Drawer Type Panel utilizes a metal-encased framework engineered for front-facing operation and servicing. Internally, the breaker, busbar, cable, and control zones are partitioned into self-contained compartments, yielding a logically structured cabinet that aids designers in formulating predictable equipment placements tailored to room geometry and cable routing prerequisites. From an upkeep standpoint, distribution networks with numerous feeders require selective maintenance protocols; a defect or scheduled examination on one circuit should not impinge upon unaffected branches. The withdrawable functional modules can be relocated to a disconnected stance for diagnostics, testing, or swapping, while an integrated mechanical interlock regimen orchestrates the operational sequence to thwart improper switching maneuvers. Consequently, the apparatus is well-suited for environments where granular circuit governance is a daily operational imperative.
To satisfy varied operational criteria, the lineup incorporates purpose-built enclosures: incoming variants for upstream power reception and medium-voltage busbar interfacing; outgoing variants for downstream power delivery to transformers, motors, and process equipment; PT cabinets for voltage transformation and system monitoring; metering cabinets for precision energy accounting; bus section cabinets for coupling or partitioning busbar runs; and isolation cabinets configured around project-specific switching orders, earthing strategies, and safety mandates. This breadth of options makes the Medium Voltage Drawer Type Panel a go-to solution across manufacturing complexes, substations, mining operations, commercial high-rises, and infrastructure installations. Whether coordinating the heterogeneous power appetites of production lines, compressors, and pumps in factories; enabling engineers to assemble substation arrays from single-line diagrams; sustaining distributed loads across mining sites; or consolidating transformer, feeder, and metering functions in large buildings and transit facilities, the Medium Voltage Drawer Type Panel unifies disparate electrical demands into a single, coherent distribution ecosystem.

The final rated voltage, current, short-circuit capacity, cabinet combination, and functional unit arrangement should be confirmed according to the project electrical diagram and technical specification.
The equipment is intended for indoor installation with an ambient temperature between -15°C and +40°C. Daily average relative humidity should not exceed 95%, while monthly average relative humidity should not exceed 90%.
The installation environment should be free from explosive or corrosive gases, conductive dust, and severe vibration. If the equipment is required to operate outside these standard conditions, the environmental requirements should be confirmed with Usune before technical design and production.
The equipment has been referenced for the Cas-space Rocket Launch Project, a specialized infrastructure project requiring an organized medium-voltage electrical distribution system.
For aerospace infrastructure, the electrical network may contain multiple types of loads serving different facilities and supporting systems. Rather than relying on one uniform cabinet arrangement, the distribution system needs to accommodate incoming power, feeder circuits, measurement functions, and other electrical requirements within a coordinated configuration.
The modular structure of the KYN28 series allows different functional cabinets to be arranged according to the project's electrical distribution scheme. This provides engineers with greater flexibility when coordinating the switchgear lineup with the facility's power network and electrical room layout.
