Auxiliary Equipment

Fault Indicator The DJD-1 short-circuit grounding fault indicator uses logic circuits for over-current alerts and manual reset, equipped with sensors on cables and a display unit for quick fault detection.

Condensation Controller Monitors ambient temperature and humidity in real-time, automatically activating integrated heaters at 85% RH to eliminate moisture buildup (rated power: 75-100W).

FTU & Communication Module The DAT-1L distribution automation terminal provides complete SCADA integration with 48 remote signaling channels, automated self-diagnosis, and protocol support for IEC101, MODBUS, and more.

Current Limiting Fuse Engineered specifically for 24kV/50Hz indoor switchgear systems (292mm length) to deliver rapid interruption against high overcurrent and short-circuit faults.

Frequently Asked Questions

What is the standard rated voltage and operational frequency?

The system operates at a standard rated operational voltage of 12kV with an alternating current frequency of 50Hz.

Which load switches are compatible with this switchgear series?

The switchgear is engineered to accommodate either FLN36-12 (Option I) or FLN48-12 (Option II) medium-voltage load break switches.

What is the ingress protection and mechanical endurance level?

The cabinet enclosure provides an IP3X protection rating and offers high mechanical durability rated for up to 2,000 standard switching cycles.

What are the maximum ambient environmental limitations?

It is rated for altitudes up to 2000m, operating temperatures from -25°C to +40°C, and seismic conditions up to Grade 8, free from corrosive gases.

How does the unit prevent internal moisture and track faults?

It features an integrated condensation controller running heating elements at 85% RH, alongside the DAT-1L FTU and DJD-1 fault indicators for real-time monitoring and automation.
