GGD AC Low Voltage Distribution Cabinet
- Product Description
-
Product Overview
Substations, industrial and mining enterprises, and other power users serve as power, lighting, and distribution equipment in AC 50HZ, rated operating voltage 380V, rated current up to 3150A distribution systems for energy conversion, distribution, and control. This product has a high breaking capacity, with a rated short-time withstand current up to 50kA. The circuit scheme is flexible, easy to combine, practical, and features a novel structure. This product is one of the representatives of China's assembled fixed-panel switchgear cabinets. This product complies with standards such as GB7251 "Low-voltage switchgear and controlgear assemblies" and IEC60439 "Low-voltage switchgear and controlgear assemblies."

Normal Operating Conditions
1. Ambient temperature: -5℃~+40℃, with an average temperature within 24 hours not exceeding +35℃
2. Altitude: 2000m and below.
3. Relative humidity: Not exceeding 50% at the highest temperature of +40℃, higher relative humidity allowed at lower temperatures (e.g., 90% at +20℃). Consideration should be given to possible condensation caused by temperature changes.
4. The inclination of the equipment installation relative to the vertical plane shall not exceed 5°.
5. The equipment should be installed in places without severe vibration and impact, and in locations that do not cause corrosion to electrical components.
Note: If users have special requirements, they can negotiate with our company.Main Technical Parameters

Auxiliary Circuit Scheme: The design of the auxiliary circuit is divided into two parts: supply point scheme and power plant scheme.
Main Busbar: Single copper busbar is used when the rated current is 1500A or below. Double copper busbars are used when the rated current is above 1500A. The overlapping surfaces of the busbars are treated with tin plating.
