The values below are computed from what you selected above. Anything that cannot be computed yet is shown as an em dash — never as zero.
Iₙ = S / (√3·U) · I_sc = 100·Iₙ / uₖ · S_sc = √3·U·I_sc · I_p = k·Iₖ
Still required to complete the calculation: rated capacity S, impedance voltage uₖ, short-time or peak withstand current.
Per-model values (P0 / Pk / uₖ declared by the factory, losses, noise, temperature rise, dimensions, weight) are not in the product library: those rows stay at an em dash until the factory parameter sheet is supplied. An em dash means the value is unavailable — it is never rendered as zero.

Pole-Mounted VCB vs Recloser vs Fusion Equipment: How to Choose
| Pole-Mounted VCB (ZW32) | Vacuum Recloser | Primary-Secondary Fusion (XGW) | |
|---|---|---|---|
| Primary device | Vacuum circuit breaker on an outdoor pole frame | Vacuum interrupter with automatic reclosing | Breaker or load switch integrated with its own automation |
| Protection | Overcurrent and earth fault through the relay | Automatic reclose sequences for transient faults | Local protection with the sensor set built in |
| Automation | DTU or FTU added to the pole | Reclose controller, with communication optional | Primary and secondary functions designed as one unit |
| Metering | Current and voltage transformers fitted separately | Basic measurement for the reclose logic | Sensors integrated in the pole unit |
| Fault isolation | Sectionalising through the upstream protection | Clears and recloses on the faulted section | Isolates the faulted section and reports it |
| Cost | Baseline | Higher, because of the reclose mechanism | Highest, since automation is built in |
| Typical application | Overhead distribution and rural feeders | Long rural feeders with transient faults | Smart-grid automation and metering points |
Where QDTB® Pole-Mounted Switchgear Is Specified
Pole-mounted switchgear is specified on overhead distribution networks where the switching point has to sit on the line rather than in a substation: rural electrification, long feeders and the boundaries between utility service areas. Mounting it on the pole removes the need for a switch house at every sectionalising point.
Automatic reclosing is what makes a long rural feeder tolerable, because most overhead faults are transient and clear when the circuit is re-energised. The recloser clears the fault, recloses and reports the event, so the utility only sends a crew when the fault is permanent.
Primary-secondary fusion equipment is specified where smart-grid automation and metering have to reach the same pole. The primary switch and its automation are designed as one unit, so the sensor set, the remote terminal and the switch share an enclosure and a wiring scheme.
Industrial and renewable plants use the same outdoor gear at the plant boundary, where the collector feeder leaves the site. Units are tested to GB 3906 and IEC 62271-200 at 12 kV to 24 kV, with integrated DTU/FTU available on the pole-mounted breakers.
Frequently Asked Questions
What is pole-mounted switchgear?
Outdoor switching and protection equipment mounted on distribution poles, including vacuum circuit breakers and automated switchgear for distribution networks.
What is primary-secondary fusion?
Fusion equipment integrates the primary switch (breaker/load switch) with secondary automation (protection, metering, communication) in a single pole-mounted device.
What voltage class is typical?
12–24 kV for medium-voltage distribution automation.
What is the minimum order quantity (MOQ) for Pole-Mounted Switchgear?
One unit for standard products. Custom-designed equipment is quoted on specifications — send your parameters or drawings and our sales team will confirm the MOQ for your configuration.
What is the delivery time for Pole-Mounted Switchgear?
Standard units are delivered in 30-45 days. Custom or large-capacity units follow a project-specific schedule confirmed at quotation. Rush orders can be accommodated for urgent projects.
Which standards and certifications do your Pole-Mounted Switchgear comply with?
They are designed and tested to GB3906, IEC 62271-200. All QDTB® equipment is ISO 9001 certified and CE marked, and the company operates ISO 9001, ISO 14001 and ISO 45001 management systems.
