Product Overview

The GGD type low-voltage fixed complete switchgear can be widely used in the AC 50Hz rated voltage 400V distribution system of power plants, substations, factories and mining enterprises, and other power users. It is used for power conversion, distribution, and control of power, lighting, and distribution equipment.

The GGD type low-voltage distribution cabinet has the characteristics of high breaking capacity, good dynamic and thermal stability, novel and reasonable structure, practical electrical scheme, strong series, applicability, and high protection level. It can be used as an updated product.

This product complies with standards such as IEC60439 "Low voltage switchgear and control equipment", GB7251.1 "Low voltage switchgear and control equipment Part 1: General", and GB7251.12 "Low voltage switchgear and control equipment Part 2: Complete power switchgear and control equipment".

Usage conditions

The ambient air temperature shall not exceed+40 ℃, not be lower than -5 ℃, and its average temperature shall not exceed+35 ℃ within 24 hours.

Weather conditions, clean air, and relative humidity not exceeding 50% at a maximum temperature of+40 ℃. Higher relative humidity is allowed at lower temperatures.

Altitude ≤ 2000m.

This product is suitable for transportation and storage at temperatures ranging from -25 ℃ to+55 ℃, and can reach+70 ℃ in a short period of time (not exceeding 24 hours).

At these extreme temperatures, the device should not suffer any irreparable damage and should be able to function normally under normal conditions.

If the above usage conditions cannot be met, the user should propose to the manufacturer and negotiate a solution when placing an order.

Technical parameters of GGD series low-voltage fixed switchgear

The GGD cabinet has broken through the structural form of old products. The basic framework is a combination assembly structure, and all structural components of the framework are firmly connected with screws. The framework, doors, and panels are phosphatized and coated with polyester orange pattern. All non sprayed parts are galvanized and passivated. The shell protection level is IP30, and it can also be selected between IP20 and IP40 according to the requirements of the user's installation site. This cabinet is designed with a good natural ventilation system.

There are commonly used upper and lower side inlet methods for GGD, and the inlet methods from the top, left, center, and right positions are also designed to meet the needs of various engineering designs for different inlet methods. At the same time, there are fixed positions inside the cabinet for special users such as power plants to install relay protection and automatic devices.

The GGD cabinet has the characteristics of high breaking capacity, good dynamic and thermal stability, and flexible and convenient electrical scheme combination.
