Frequently Asked Questions
What is a GGD AC Low-Voltage Distribution Cabinet?
GGD is a type of fixed-installation distribution cabinet used in power plants, substations, and industrial enterprises for power conversion and distribution in AC 50Hz systems with a rated voltage of 380V.
How do I choose between GGD1, GGD2, and GGD3?
The choice depends on your required breaking capacity: GGD1 is rated for 15kA, GGD2 for 30kA, and GGD3 for 50kA. Select based on your system's short-circuit current requirements.
What type of busbar is used in these cabinets?
For rated currents up to 1500A, aluminum busbars are standard. For currents exceeding 1500A, high-quality copper busbars are utilized. All joints are tin-plated for better conductivity.
Can these cabinets handle reactive power compensation?
Yes, the GGD series includes specific circuit schemes designed for reactive power automatic compensation and electric energy metering.
Are the internal components customizable?
Absolutely. While there are standard schemes, you can specify component models and specifications in your ordering drawings to meet your specific project requirements.
What information is necessary for a quotation?
Please provide the main circuit diagram, auxiliary circuit diagram, list of primary components, cabinet dimensions, and any specific surface finish requirements.
