product introduction:
KGDC series DC cabinet is suitable for rated voltage DC1800V (nominal voltage DC1500V) and below, with a maximum rated current of 4000A. It is used as a complete set of equipment for DC traction power supply and distribution, and provides electrical protection and isolation functions for the main circuit. Widely used in underground and surface applications in non-gas explosion hazardous mines. This series of products mainly includes incoming cabinet, feeder cabinet, negativ

product features:

  1. Fully enclosed metal structure, good sealing performance, anti-corrosion, anti-splash water, dust, suitable for long-term operation in harsh mining environment.
  2. Core protection: DC overcurrent, overload, short circuit, overvoltage, undervoltage, automatic reclosing and fault diagnosis.
  3. Modular design, the circuit breaker adopts handcart structure, which can be removed as a whole, which is convenient for rapid equipment maintenance.
  4. Equipped with microcomputer integrated protection device, all Chinese LCD touch screen, integrating display, control, protection and communication, realizing remote monitoring operation and intelligent management.
