Ordering Notice

Product operating site and special requirements:

  1. Provide product ordering drawings, which should include wiring diagrams and indicate transformer capacity, main component model specifications, distribution branch circuits, and capacity.
  2. When it is necessary to configure electric energy metering and reactive power automatic compensation devices, the requirements for the configuration of the metering meter and transformer should be provided, and the capacity of the compensation capacitor should be indicated.
  3. Specify the requirements for surface treatment of the product.

Frequently Asked Questions (FAQ)

Q1: What are the primary differences between GGD1, GGD2, and GGD3 models?

The primary difference lies in their breaking capacity and rated current limits. GGD1 provides up to 15kA breaking capacity (up to 1000A), GGD2 handles up to 30kA (up to 1600A), and GGD3 accommodates heavy-duty applications up to 50kA breaking capacity with currents up to 3150A.

Q2: What busbar materials are used in GGD distribution cabinets?

Aluminum busbars are utilized for rated current applications ≤1500A, while high-conductivity copper busbars with tin-plated joints are implemented for systems exceeding 1500A to ensure thermal and electrical efficiency.

Q3: Can GGD cabinets support automatic reactive power compensation?

Yes, GGD cabinets offer dedicated circuit schemes that support reactive compensation devices. Details regarding capacitor capacity and transformer requirements must be specified during the ordering process.

Q4: What technical details should be provided when placing an order?

Orders require comprehensive wiring diagrams showing transformer capacity, component specifications, circuit branch capacities, metering configurations, and any custom requirements for cabinet surface treatment.

Q5: What protective mechanisms are included for auxiliary circuits?

Auxiliary circuits feature dual power supply control schemes and are equipped with LMZ3D current transformers to achieve effective relay protection and monitoring.
