GGD LV Switchgear Assemblies

Overview

The drawer type switchgear is an advanced LV switchgear developed to meet the demands of the electric power industry development with reference to the design and improvement of foreign MNS series LV switchgear, which is designed in accordance with national standards GB7251, VDE660, and ZBK36001-89, Low-voltage Withdrawable Switchgear Assemblies, and international standard IEC439. MNS type switchgear is suitable for various kinds of needs of power supply, distribution, and can be widely applied for power plants, substations, industrial and mining enterprises, buildings and hotels, municipal construction and other LV power distribution systems.

• The GCK drawer type switchgear is widely applied for power plants, substations, power distribution center (PC) and motor control center (MCC) of industrial and mining enterprises and high-rise buildings, as LV distribution equipment assemblies for the distribution, MCC, reactive power compensation in power generation and supply systems with AC frequency of 50-60Hz, rated working voltage up to 660V, and rated current up to 6300A.

Features

• Modular design, easy maintenance

• High interchangeability, providing reliability and continuity of power supply

• Up to 22 circuits fora single MCC cabinet

• Incoming and outgoing methods to meet the demands of various applications

• Functional unit circuits being distinctively indicated for OFF, Test, ON positions

• Both the functional units and the chambers are respectively partitioned clearly and reliably, which are not affected by a faulty unit, minimizing the range of fault

• Good stability of the busbar horizontal arrangement, able to withstand the impact of 80/176kA short-circuit current

• The connection between the unit and external cables is completed in the cable chamber, and the cables come in and go out from the top and bottom
