Product Description
The medium voltage metal enclosed switchgear is developed for 24 kV distribution systems that require high current capacity, dependable fault interruption, and organized metal-clad construction. The KYN28-24/3150-31.5 model is configured for 24 kV rated voltage, 3150 A rated current, and 31.5 kA short-circuit breaking capacity. It can serve as incoming, feeder, bus-coupler, transformer, capacitor, metering, or station-service equipment within a coordinated switchgear lineup. Our medium voltage metal enclosed switchgear separates the circuit breaker, busbar, cable, and low-voltage control compartments to improve operating discipline and maintenance access. A withdrawable vacuum circuit breaker can be moved between service, test, and disconnected positions according to the design, while mechanical and electrical interlocks support the intended operating sequence. The cabinet is not treated as an isolated panel; the arrangement is reviewed as part of the complete substation, including incoming cable direction, busbar connection, protection coordination, control power, communication, room dimensions, and future extension requirements.
We manufacture medium voltage metal enclosed switchgear in a factory that combines enclosure processing, component assembly, wiring, testing, and after-sales support. With more than 40 years of operation, a 36,000-square-meter facility, and 128 employees, Jiangsu Guoxing Electric Equipment Co., Ltd. can manage both repeat production and project-specific engineering. CNC fabrication accuracy up to ±0.1 mm for applicable sheet-metal parts supports consistent section alignment and reliable movement of withdrawable equipment. The medium voltage metal enclosed switchgear can be customized with customer-specified circuit breakers, relays, instrument transformers, meters, arc-protection devices, communication gateways, and cable interfaces. Production is controlled by model-specific quality documents, and every finished cabinet receives 100% inspection before packing. The factory can provide inspection records, production photos or videos, and third-party inspection access when requirements are defined in advance. Standard products are normally scheduled in about five working days, while customized orders generally require seven to fifteen working days after technical approval. This disciplined but flexible process helps distributors and EPC contractors reduce technical risk while maintaining room for local-brand components, private labeling, and market-specific documentation.
