Product descriptions from the supplier
Descripton：
Single-phase pad-mounted transformers are the preferred choice among base-mounted transformers, offering a balance of environmental friendliness, economic efficiency, high efficiency, and safety. These transformers utilize FR3 high-flash-point insulating fluid, providing excellent fire protection performance. Compared with traditional mineral oil transformers, their expected service life is significantly extended. The rated power of these transformers ranges from 10 to 167 kVA, and they are available in various designs such as ANSI Type 1, ANSI Type 2, and Ranch Runner, making them suitable for different application scenarios.
Features：
The FR3 fluid is not only biodegradable and non-toxic, but also capable of delivering sustainable performance at an affordable cost. This fluid strictly complies with the ASTM D6871-03 standard and meets the requirements of the IEEE PC57.147 standard which is under application.
The product performance fully meets or even exceeds multiple industry standards, covering ANSI (excluding the Ranch Runner front panel), NEMA, and DOE energy efficiency standards.
The core and coils are meticulously designed to achieve high reliability and significantly reduce the on-site failure rate. It offers two material options: grain-oriented steel and amorphous steel.
The overcurrent protection is well-configured, with Bay-O-Net fuses as standard, and optional current-limiting fuses or weak link components can be selected according to needs.
Both high-voltage and low-voltage bushing terminals are tinned, which can accommodate aluminum or copper conductors to ensure stable and efficient electrical connections.

Impact of DC Bias in Transformers at Renewable Energy Stations Near UHVDC Grounding ElectrodesImpact of DC Bias in Transformers at Renewable Energy Stations Near UHVDC Grounding ElectrodesWhen the grounding electrode of an Ultra-High-Voltage Direct Current (UHVDC) transmission system is located close to a renewable energy power station, the return current flowing through the earth can cause a rise in ground potential around the electrode area. This ground potential rise leads to a shift in the neutral-point potential of nearby power transformers, inducing DC bias (or DC offset) in their01/15/2026 -
HECI GCB for Generators – Fast SF6 Circuit Breaker1.Definition and Function1.1 Role of the Generator Circuit BreakerThe Generator Circuit Breaker (GCB) is a controllable disconnect point located between the generator and the step-up transformer, serving as an interface between the generator and the power grid. Its primary functions include isolating generator-side faults and enabling operational control during generator synchronization and grid connection. The operating principle of a GCB is not significantly different from that of a standard c01/06/2026 -

How to Test Insulation Resistance of Distribution TransformersIn practical work, insulation resistance of distribution transformers is generally measured twice: the insulation resistance between thehigh-voltage (HV) windingand thelow-voltage (LV) winding plus the transformer tank, and the insulation resistance between theLV windingand theHV winding plus the transformer tank.If both measurements yield acceptable values, it indicates that the insulation among the HV winding, LV winding, and transformer tank is qualified. If either measurement fails, pairwise12/25/2025 -
