GGD Switchgear Introduction

GGD low-voltage switchgear, also called GGD fixed cabinet, is a GGD type AC low-voltage power distribution cabinet used for fixed wiring low-voltage power distribution cabinets. It is divided into three types: GGD1/GGD2/GGD3, with different segment current capabilities.

Application Channels:

Used for power users such as power plants, substations, factories and mines, as AC 50-60Hz, used in power distribution systems with rated operating currents up to 3150A. Used for power conversion, distribution and control of power, lighting and power distribution equipment.

Structural Features

According to the purpose, it is divided into: power receiving cabinet, busbar connection cabinet, feeder cabinet, motor control cabinet, reactive power compensation cabinet, lighting distribution cabinet.

Cabinet structure:

(1) The cabinet frame is partially welded and assembled with 8MF cold-formed steel.

(2) The ZMJ type busbar clamp, which is thermoformed with high flame retardant PPO material, has a modular structure with high mechanical strength and insulation.

(4) The cabinet door is connected to the frame with a galvanized shaft hinge, which is convenient for installation and disassembly.

(5) The grounding knurled screw structure is used between the installation parts in the cabinet and the frame to form a complete grounding protection circuit.

Precision Manufacturing System

1. Micron-level precision manufacturing

Equipped with ±0.1mm high-precision industrial robots, it realizes millimeter-level control of switch cabinet bending and assembly, with a standardization rate of parts ≥99% and a size qualification rate of over 99.5%.

2. German imported spraying system

Adopting electrostatic spray guns and water-based environmentally friendly paint, the coating uniformity error is ≤5μm, VOC emissions are reduced by 80%, and "zero-defect appearance" and green manufacturing are achieved simultaneously. The spraying defect rate is controlled within 0.3%.

3. Fully automated production

Relying on Schneider's benchmark intelligent production line, a fully automated production model is created, manual intervention is reduced by 70%, the production cycle of a single cabinet is compressed to 30 minutes, and the production capacity is increased by 30%.

Core Advantages Of Digital Production Lines

1. Using the dual engines of "data + intelligence" to drive manufacturing innovation and build an industry-leading digital production system.

2. Relying on 220+ sets of intelligent equipment clusters, unmanned operation of the entire process from sheet metal processing to finished product assembly is realized, the manual intervention rate of key processes is less than 5%, and the yield rate exceeds 99.8%.

3. The U-shaped layout and modular design increase material handling efficiency by 40%, produce 10,000 high and low voltage equipment each year, and shorten the order delivery cycle by 30%.

4. AGV logistics and digital twin systems are linked to achieve 72 hours of unmanned continuous operation, and the capacity utilization rate reaches more than 95%. 5. Green manufacturing, waste recovery rate exceeds 90%, noise and emission indicators are 20% better than the national standard, and it has been rated as a provincial smart factory benchmark.
