Description
Product Introduction
Our company has developed a new product—the single-phase shell-type distribution transformer mounted on an iron core column—specifically in response to market demand. This transformer features a highly efficient design that significantly reduces energy losses. By placing single-phase transformers closer to the load centers, it helps minimize transmission line losses and enhances the reliability of power supply. Widely used in urban and rural distribution networks as well as residential communities, this product delivers remarkable economic and social benefits.
Implementation Standards
IEC 60076-1:2011 Power Transformers
GB1094.1-2013 Power Transformers
JB/T10317-2014 Single-Phase Oil-Immersed Distribution Transformer: Technical Parameters and Requirements
JB/T10088-2016: Sound Levels for 6kV to 500kV Power Transformers
Model and Meaning
Structural Features
1. Low iron loss, small no-load current
Since the wound core has seamless construction, all magnetic flux is magnetized in the same direction as the rolling direction of the silicon steel sheets. After annealing, the process loss coefficient of the wound core becomes balanced, fully leveraging the grain-oriented properties of the silicon steel sheets. Under identical conditions, the no-load losses of the wound core are reduced by 7–10% compared to those of a laminated core, while the no-load current can be lowered by 50–70%.
2. Low noise
The seamless rolled core structure, manufactured using specialized equipment that ensures the core is tightly wound into a single, solid unit, reduces noise by approximately 5 dB compared to stacked cores under identical conditions.
3. Rolled-iron core products exhibit strong resistance to sudden short circuits and boast excellent operational reliability. A transformer's ability to withstand short circuits—and its overall reliability—depend on three critical tightening mechanisms: "clamping, bracing, and pressing." While conventional laminated-core transformers require careful attention to ensuring these three tight connections between the core and windings, seamless rolled-iron core distribution transformers only need to focus on securing the windings themselves. This streamlined approach further highlights the design’s simplicity and superior reliability.

| Note 1: Performance parameters for products with other capacities shall be determined through negotiation between the manufacturer and the user. Note 2: For transformers with a low-voltage combination of 2 × (0.22–0.24) kV, the rated capacity is halved when the low voltage is at (0.22–0.24) kV—except in cases where they are used in parallel. Note 3: For other short-circuit impedance values, the manufacturer and user shall negotiate and agree upon them. | ||||||||
