GGD1\/GGD2\/GGD3 AC Low-Voltage Power Distribution Cabinet (Feeder Cabinet)<\/h1>\n\n\n\n

1. Product Overview<\/h2>\n\n\n\n

GGD series feeder cabinet is fixed-type low-voltage distribution switchgear for AC 50\/60Hz, 400V three-phase four-wire systems, complying with IEC 60439-1 and GB 7251.1 standardsMade-in-Ch…. It adopts rigid 8MF cold-bent steel frame with IP30 protection grade, matched with main incoming, bus coupler and compensation cabinets. Its core function is to divide main bus power into multiple independent outgoing branches, supplying power to workshop equipment, lighting, building power distribution boxes and motor loads, with independent overload, short-circuit and leakage protection for each circuit. GGD1, GGD2 and GGD3 differ in short-circuit withstand capacity and bus carrying current to cover small, medium and large load distribution projects worldwide.<\/p>\n\n\n\n

2. Standard Internal Configuration<\/h2>\n\n\n\n
    \n
  1. Molded Case Circuit Breaker (MCCB): Each outgoing loop is equipped with MCCB for branch fault isolation; optional leakage protection modules.<\/li>\n\n\n\n
  2. Current Transformer (CT): Matched with ammeters and multi-function meters to monitor branch current and power consumption.<\/li>\n\n\n\n
  3. Main Copper Busbar System: Top-through L1\/L2\/L3 phase busbars, separate N neutral busbar and PE grounding busbar; all joints are tinned to reduce contact resistance.<\/li>\n\n\n\n
  4. Measuring & Indication Panel: Ammeter, running\/fault indicator lights for real-time branch status observation.<\/li>\n\n\n\n
  5. Secondary Terminal Block: Centralized wiring for remote signal transmission and monitoring communication.<\/li>\n\n\n\n
  6. Cable Compartment: Bottom cable inlet and outlet, convenient for laying power cables to terminal loads.<\/li>\n<\/ol>\n\n\n\n

    4. Working Principle<\/h2>\n\n\n\n

    Power from the main busbar of the low-voltage system enters the feeder cabinet through top copper busbars. Each independent branch is controlled by a dedicated MCCB, which distributes power to different terminal loads via underground cables.<\/p>\n\n\n\n

      \n
    • Normal operation: Each branch operates independently to supply power to designated equipment without mutual interference.<\/li>\n\n\n\n
    • Fault protection: Once overload, short circuit or leakage occurs on any branch, the corresponding MCCB trips automatically, only cutting off the faulty circuit without affecting the whole bus section.<\/li>\n\n\n\n
    • Real-time monitoring: CT collects branch current signals, displaying operating data on the instrument panel and supporting remote uploading to power monitoring systems.<\/li>\n<\/ul>\n\n\n\n

      5. Core Selling Points for Foreign Trade Website<\/h2>\n\n\n\n
        \n
      1. Complete model coverage: GGD1 for light loads, GGD2 universal standard type, GGD3 high-current heavy industrial type, flexible matching all transformer capacities.<\/li>\n\n\n\n
      2. Multi-loop independent distribution design: Single-circuit fault will not paralyze the whole power supply system, greatly improving system stability.<\/li>\n\n\n\n
      3. Multi-layer safety protection: Branch MCCB protection + integral cabinet grounding + IP30 anti-touch protection, eliminating live contact risks.<\/li>\n\n\n\n
      4. Optimized heat dissipation structure: Upper and lower ventilation slots reduce internal temperature, supporting 24-hour continuous stable operation.<\/li>\n\n\n\n
      5. Strong system compatibility: Freely combined with full set of GGD low-voltage cabinets to form single-section or double-section bus power distribution systems.<\/li>\n\n\n\n
