LOW VOLTAGE SWITCHGEAR | LV SWITCHGEAR

• The GoWatron GCS Low-Voltage Withdrawable Switchgear is a modular low-voltage switchgear and controlgear assembly designed for power distribution systems in power plants, oil and gas facilities, petrochemical plants, metallurgical facilities, textile mills, industrial plants, high-rise buildings and infrastructure projects.
• It is suitable for three-phase AC systems operating at 50/60 Hz, with a rated operational voltage of up to 690 V and main busbars rated up to 4,000 A. The switchgear can be used for receiving, converting, distributing and controlling electrical power, as well as for centralised motor control and reactive power compensation.
• For highly automated applications, the switchgear can be equipped with auxiliary contacts, measuring devices, communication interfaces and intelligent monitoring units according to project requirements. This configuration enables integration with power monitoring and automation systems.
• The GCS switchgear features a compartmentalised arrangement and withdrawable functional units. Its modular construction combines a compact footprint and flexible circuit configuration with ease of operation and straightforward maintenance. Each assembly can be customised according to the project single-line diagram, load characteristics and installation conditions.

The GGD low-voltage grid-connected photovoltaic switchgear is a modular fixed-type low-voltage complete switchgear and controlgear assembly. It is designed and manufactured in strict compliance with GB/T 7251 series national standards for low-voltage switchgear and controlgear assemblies, IEC 61439 international standards, and NB/T 32004 technical specifications for photovoltaic grid-connected systems. Suitable for low-voltage distributed photovoltaic power generation systems with a rated operating voltage of AC 400V/380V and a rated frequency of 50Hz, the equipment serves as the core grid-connection interface device positioned at the Point of Common Coupling (PCC) between photovoltaic power stations, public power grids, and users’ internal distribution networks. The equipment adapts to photovoltaic systems with installed capacities ranging from 200kWp to 2000kWp and above, and is widely applied in new energy scenarios including industrial and commercial rooftop distributed PV systems, village-level centralized PV power stations, and solar-water complementary power plants.

Installed in series between the AC output side of inverters and the grid incoming line, the equipment integrates core functions including grid-connected power feeding, electrical energy metering, fault protection, safety disconnection, and grid adaptability regulation. Under normal operating conditions, the equipment stably delivers clean power. In the event of grid-side or equipment-side abnormalities or faults, the equipment performs rapid and reliable disconnection to isolate fault points effectively, ensuring the operational safety and power supply reliability of both PV power generation systems and public distribution networks.
