DESCRIPTION
Product Description |
The GGD low voltage switchgear is applied in power plants, substations, industry and mine corporations, etc. with rated voltage 400V, max operating current 4000A and rated frequency 50/60Hz. It can be applied as power conversion distribution control, distribution and control of power, lighting and power distribution, etc.
The device adheres to IEC61439 and GB7251.1 "Low-voltage switchgear and controlgear assemblies" etc.
Structure |
Cabinet frame
The cold-rolled steel plate is bent and welded, and the surface is electrostatically sprayed after pickling and phosphating, which has anti-corrosion and anti-rust capabilities.
It is divided into horizontal busbar room, circuit breaker room, cable room and instrument room, and the modular design is convenient for installation and maintenance.
Main components
Busbar system: The horizontal busbar is placed on the top of the cabinet, using copper or aluminum bars to support large current transmission (up to 3150A).
Circuit breaker: Configure frame type (such as DW15) or molded case circuit breaker (such as DZ20) to provide overload and short circuit protection.
Isolating switch: used for circuit isolation to ensure maintenance safety.
Instrument and protection device: Install voltmeter, ammeter and smart meter (optional), support power monitoring and communication functions.
Features |
Fixed installation design
All electrical components are fixedly installed, with a simple and reliable structure and low cost, but the scalability is weaker than that of drawer-type cabinets.
High safety and protection
The protection level is IP30 (IP40 can be customized), suitable for dry environments. The internal partition isolation reduces the risk of fault propagation.
Flexible configuration
Supports more than 200 main circuit schemes (such as incoming lines, contacts, feeders, motor control) to meet diversified power distribution needs.
Strong dynamic thermal stability
Short-time withstand current grading: horizontal bus 15kA/30kA/50kA (1 second), vertical bus 30kA/63kA.
Application |
Industrial and mining enterprises: workshop power distribution, lighting control.
Commercial buildings: building power distribution room, data center power distribution.
Infrastructure: low-voltage side of substation, port/airport power system.
New energy: low-voltage grid-connected cabinets for photovoltaic power generation systems.
