Remarkable Advantages of Unicore Switchgear
Fire Safe and Pollution Free
Oil-free epoxy resin construction completely eliminates fire and liquid leakage risk. Units install directly at the load center inside occupied buildings — no dedicated transformer room, fire suppression system, or containment infrastructure required. Suitable for hospitals, subways, and any environment where fire safety is non-negotiable.
Low Loss and High Efficiency
The core uses grain-oriented cold-rolled silicon steel with a 45-degree full-staggered joint structure, ensuring low no-load losses across the full capacity range. The amorphous alloy core option reduces no-load losses by up to 75% and load losses by up to 15%, delivering measurable energy savings over the transformer’s full service life.
Strong Overload Capacity
Excellent heat dissipation and high thermal stability support reliable operation under sustained overload conditions without compromising performance. Forced air cooling is available on the SCB series for higher capacity operation. The SGB series sustains 120% continuous overload under IP45 protection without any forced cooling required.
Moisture and Corrosion Resistant
High-voltage windings are fully vacuum-cast in epoxy resin, forming a sealed rigid body that blocks moisture, harmful gases, and corrosive chemicals. Reliable in coastal environments, chemical plants, tunnels, and other harsh conditions where conventional units would require additional protection.
Intelligent Temperature Monitoring
The intelligent temperature control system automatically monitors all three-phase winding temperatures in real time, starts and stops cooling fans based on live readings, and includes fully configurable alarm and trip functions. Ensures safe, unattended operation around the clock under all operating conditions.
Smart Monitoring and Zero Maintenance
No oil to inspect, test, or replace — eliminating routine maintenance requirements and reducing lifetime operating costs. Remote monitoring provides real-time visibility of equipment status, enabling centralized management of multiple units without on-site inspection.

What Our Clients Say
Low Noise Performance, SCB-RL Series
“We installed the SCB-RL three-dimensional wound core dry type transformers for a subway station project. The noise level during operation is noticeably lower than units we have used before, which was a key requirement for the project. The three-phase magnetic circuit design performs consistently under varying load conditions. Commissioning was straightforward and the units have been running without issue.”

⭐⭐⭐⭐⭐
Precision Performance at 35kV, SCB Series
“We specified the 35kV SCB series for a large-scale industrial power distribution project. The units arrived well-packaged and in perfect condition. Electrical performance matched the rated specifications exactly during our acceptance testing. The epoxy resin encapsulation has held up well in our outdoor substation environment. A dependable product from a supplier we would work with again.”
