Brand: WEIJI
USES: High reliability low voltage complete distribution system
KYN28A-24 is a relatively common high-voltage switchgear at present, rated voltage is 24kV. The equipped vacuum circuit breaker is in the middle of the switch cabinet, that is, the circuit breaker is located in the middle of the front cabinet of the switchgear, so the lower space can be saved for the expansion of other schemes or used as a cable room.
Mainly used in power plants, substations, transformation and distribution centers of industrial and mining enterprises, and large-scale high-voltage motor starting equipment, etc., for receiving and distributing electric energy, and for controlling, protecting and monitoring circuits.
1. The German-imported spray coating system utilizes an electrostatic spray gun and water-based environmentally friendly paint, resulting in a coating uniformity error of ≤5μm and an 80% reduction in VOC emissions. This simultaneously achieves a “zero-defect appearance” and green manufacturing, with a spray defect rate of less than 0.3%.
2. The cabinet structure features a center-mount design, offering a compact form factor, excellent interchangeability, and ample cable compartment space for easy installation and maintenance.
3. Equipped with advanced Schneider vacuum circuit breakers or high-quality domestic vacuum circuit breakers, the system offers superior performance.
4. The enclosure has an IP4X protection rating, maintaining IP2X even when the circuit breaker compartment door is opened.
5. The product features comprehensive “five-protection” interlocking functions to ensure operator safety.
6. The main busbar current rating is 4000A, the short-circuit breaking current is 50kA, and the mechanical life is 20,000 cycles.
