Pole Mounted Automatic Circuit Recloser

Smart Grid-Ready Reclosing Protection for Rural & Urban Power Systems

Unplanned power outages caused by transient faults, falling branches, or lightning strikes can severely impact reliability. The Pole Mounted Auto Recloser from Wei Shoe Electric is designed to automatically detect, isolate, and restore power in overhead medium voltage distribution networks. Whether you're maintaining long rural feeders or urban grids, this compact, intelligent solution minimizes downtime and improves grid stability—without requiring on-site intervention.

⚙️ What Is a Mounted Auto Recloser?

An auto recloser is a switchgear device that automatically opens and recloses a line when a fault is detected. Installed on distribution poles (typically at 11kV–33kV), it is essential in modern power grids for:

• Reducing service interruptions from temporary faults

• Preventing cascading outages

• Allowing remote monitoring and operation via SCADA

Wei Shoe’s unit integrates a vacuum interrupter, an intelligent controller, voltage/current sensors, and a communication module into a weatherproof body.

✅ Key Benefits

• Voltage range: 11kV / 15kV / 24kV / 33kV

• Rated current: 630A / 800A

• Breaking capacity: 16kA–25kA

• Insulation: Solid dielectric (no SF6 gas)

• Reclosing cycles: Programmable (1–4 times)

• Control modes: Local, Remote (via SCADA), Auto

• Standard compliance: IEC 62271-111, IEEE C37.60

📈 Real-World Application: Uganda Rural Grid Modernization (2023)

In 2023, Wei Shoe Electric supplied 40 sets of 15kV pole-mounted reclosers to the Uganda Electricity Distribution Company Ltd (UEDCL). These units were installed on 60–90km rural feeders to:

• Reduce manual fault patrol distance

• Improve SAIDI/SAIFI indices

• Enable fault isolation via GSM remote control

After 12 months, the recorded fault clearance time dropped by 78%, with zero SF6 gas leakage reported.

🔍 Ideal For These Applications

• Rural medium-voltage feeders with long spans

• Overhead lines with vegetation risks

• Mini-substations and pole transformer protection

• Microgrid sectionalizing and renewable energy tie-ins

• Smart grid SCADA integration projects

📊 Technical Parameters

❓ Frequently Asked Questions

• What is the difference between a recloser and a circuit breaker?
A recloser automatically recloses after a fault; circuit breakers generally trip and remain open until manually reset.

• Does it require a SCADA system to operate?
No, it can operate independently in automatic mode or be connected to SCADA via GSM, GPRS, or IEC 61850 protocols.

• Can it be used in remote areas without internet?
Yes, reclosers support GSM-based control and also offer local manual operation.

• Is there any maintenance needed?
Minimal. No SF6, no oil. Annual inspection of contacts and control module is sufficient.

• What standard tests has it passed?
All units are type-tested according to IEC 62271-111 and IEEE C37.60.
