100% drawer interchangeability

The draw er unit adopts standardized design,and draw ers of the same specification are completely interchangeable with out the need for adjustment The test can be directly pu into operation,and the replacement time of the faulty unit is shortened to within 5 minutes

High current carrying electrical performance

The main busbar adopts high conductivity oxygen free copper bars,with a rated current of up to 2000A- 5000A,Rated short-time withstand current up to 50kA/1s
peakw ithstand current 125KA,Capable of withstanding short-circuit impact of heavy industrial loads and temperature rise control ≤55K

Intelligent monitoring operation and
maintenance

Buit in inteligent measurement and control module,supports RS485/Modbus communication protocol,can be connected Entering the distribution automation system to achieve remote telemetry,remote signaling,and remote control;Draw er list Equippedwith status indicator lights and fault alarm devices,
on-site operation and maintenance visualization.

Multiple safety interlocks

The draw er is equippedw ith a three position mechanical lock for worktest/separation,and the cabinet door is connected to the drawer Implement mandatory interlocking of drawers and circuit breakers to prevent mis operation;Protection level up to IP30 (optional IP40),dustproof and moisture-proof,suitable for complex industrial electrical environments.

Compact modular design

The cabinet is assembledwith C-shaped steel,and the drawer module is 8E/16E/20E/24E (1E=25mm),Flexible combination of incoming and outgoing lines,capacitor compensation,and frequency conversion Control and other functional units have a 20% increase in
