125 kVA SBH21 Amorphous Alloy Distribution Transformer

Product Advantages

Capacity for Growing Local Feeders

The 125 kVA rating offers more headroom for mixed residential, commercial or light-industrial demand when supported by the load study.

Reduced Standing Loss

The amorphous alloy core addresses energy consumed while the transformer is energized, including periods of light load.

Sealed Oil System

The tank design limits exposure of insulating oil to atmosphere and supports reduced routine maintenance.

ONAN Thermal Performance

Cooling relies on natural oil and air circulation, avoiding auxiliary fan power and controls.

Connection Flexibility

Voltage, tap range, vector group, conductor and accessories are finalized for the network interface.

Product Details

125 kVA SBH21 Amorphous Alloy Distribution Transformer

Product Introduction

The 125 kVA SBH21 oil-immersed amorphous alloy transformer serves small utility, community and commercial feeders that require dependable continuous distribution with reduced no-load loss. Compared with the 80 kVA page, this rating targets a larger diversified load and should be checked for growth allowance, voltage regulation and downstream protection.

Typical Applications

Typical uses include community distribution, commercial branch feeders, municipal services, agricultural processing and light-industrial sites. Compare the expected load curve and annual losses when choosing between 80 kVA, 125 kVA and larger ratings.

Frequently Asked Questions

How does this page differ from the 80 kVA model?

The 125 kVA unit serves a higher calculated demand and may provide different growth headroom; loading, losses, impedance and protection must be checked for the specific design.

What should be compared for lifecycle cost?

Review purchase cost, guaranteed no-load and load losses, expected load curve, energy price, service life and maintenance requirements.

Which accessories can be specified?

Accessory selection depends on utility practice and project needs; list required bushings, indicators, protection devices, terminal arrangement and monitoring in the RFQ.
