The Medium Voltage Drawer Type Panel supports power receiving, feeder distribution, voltage measurement, metering, bus sectioning, and isolation functions. Usune provides the equipment with an engineering-oriented configuration approach and operates under ISO 9001, ISO 14001, and ISO 45001 management systems, with products designed according to applicable IEC and GB standards and CE certification available for relevant markets.
Large electrical projects often contain multiple independent power circuits rather than a single distribution line. Incoming power, transformer feeders, motor circuits, metering circuits, and auxiliary loads may all require different electrical functions.
The KYN28 Medium Voltage Drawer Type Panel allows these functions to be arranged as separate cabinets within one coordinated lineup. This makes it possible to build a distribution system around the project's single-line diagram instead of using a uniform cabinet configuration for every circuit.
For procurement teams, this modular architecture can simplify equipment specification because cabinet functions can be defined according to the actual electrical network. It also allows the overall lineup to be planned according to the number of feeders, current requirements, protection arrangements, and future distribution needs.
The configuration of a medium-voltage distribution system depends heavily on the function of each circuit. An incoming circuit receives electrical power from an upstream source, while outgoing circuits distribute power to transformers, motors, production equipment, or other loads.
Usune can configure the KYN28 series with incoming cabinets, outgoing cabinets, PT and voltage measurement cabinets, metering cabinets, bus sectionalizer cabinets, and isolation cabinets. Each cabinet type can be integrated into the overall switchgear lineup according to the project's electrical architecture.
This circuit-based approach is particularly useful for EPC projects where the switchgear specification must correspond closely with the approved electrical drawings.
Electrical distribution requirements can change as factories expand, production lines are added, or infrastructure capacity increases. A switchgear lineup that is planned only for the initial electrical load may become difficult to modify when additional feeders are required.
The modular arrangement of the KYN28 series provides greater flexibility for organizing different circuits within a medium-voltage distribution system. During project planning, customers can reserve suitable positions or define additional functional cabinets according to expected future requirements.
This approach allows the switchgear system to be considered as part of the project's longer-term electrical architecture rather than only as an individual piece of equipment.
The physical arrangement of medium-voltage equipment is an important consideration for electrical room design. Equipment needs to provide sufficient operating access while fitting within the available installation area.
The KYN28 Medium Voltage Drawer Type Panel uses a metal-enclosed structure with front-side operation and maintenance. The breaker, busbar, cable, and control sections are arranged as independent compartments, creating a clearly organized cabinet structure.
For electrical room designers, this configuration helps establish a more predictable equipment layout and allows the switchgear lineup to be planned around the available room dimensions and cable connection requirements.
In a distribution system containing multiple feeders, maintenance requirements can vary between individual circuits. A fault or planned inspection on one circuit should be managed according to the electrical operating procedure without unnecessarily disturbing unrelated sections.
The withdrawable functional unit allows the relevant equipment to be moved to an isolated position for inspection, testing, or replacement. The mechanical interlocking system controls the operating sequence and helps prevent incorrect switching actions.
This makes the equipment suitable for distribution systems where individual circuit management is an important part of daily electrical operation.
The incoming cabinet is used to receive electrical power from the upstream power source and connect it to the medium-voltage busbar system. Its configuration can be determined according to the incoming circuit's rated current, protection requirements, measurement requirements, and overall distribution architecture.
Outgoing cabinets distribute medium-voltage power to downstream transformers, motors, feeders, or other electrical loads. The number and specification of outgoing cabinets can be planned according to the project's load distribution and feeder arrangement.
The PT cabinet is used for voltage measurement and related electrical monitoring functions. It can be integrated into the switchgear lineup where the project requires voltage transformation and measurement within the medium-voltage distribution system.
The metering cabinet can accommodate electrical energy measurement equipment for applications requiring dedicated power metering. Its configuration can be coordinated with the project's measurement and utility requirements.
The bus sectionalizer cabinet is used to divide or connect sections of the medium-voltage busbar according to the system design. This arrangement can provide greater flexibility when designing distribution networks with multiple power sources or bus sections.
The isolation cabinet provides a dedicated configuration for electrical isolation requirements. Its arrangement should be determined according to the project's switching sequence, grounding scheme, and electrical safety procedures.
Manufacturing facilities often contain production lines, motors, transformers, compressors, pumps, and auxiliary systems with different power requirements. A modular switchgear lineup can organize these circuits according to the factory's electrical distribution structure.
Substations may require multiple incoming, outgoing, measurement, and bus section circuits. The modular cabinet arrangement allows engineers to develop a complete switchgear lineup based on the substation's single-line diagram.
Mining operations typically involve multiple electrical loads distributed across different areas of the site. The equipment can be configured to support feeder distribution and power management for motors, pumps, ventilation systems, and processing equipment.
Large commercial and high-rise buildings require organized medium-voltage power reception and distribution. Different cabinet functions can be combined according to the building's transformer, feeder, metering, and electrical room requirements.
Infrastructure projects such as transportation facilities and specialized industrial installations may contain multiple electrical loads with different operating requirements. The modular configuration provides flexibility for integrating these circuits into one coordinated medium-voltage distribution system.

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.
