Zhejiang Jiangshan Hengli Electrical Co., Ltd. is one of the leading manufacturers and suppliers of 200kva smart distribution transformer in China. If you're going to wholesale durable 200kva smart distribution transformer made in China, welcome to get pricelist from our factory. All customized products are with high quality and low price.
The 200kVA smart distribution transformer is a compact and highly efficient solution designed for reliable low-voltage power distribution. The rated capacity of the transformer is 200 KVA. the primary voltage of the transformer is 11 KV and secondary is 400 V. As a professional transformer manufacturer with full in-house production, we deliver stable, cost-effective transformers directly from our factory, eliminating unnecessary intermediaries.
This model is engineered using advanced electromagnetic design and high-quality materials such as cold-rolled grain-oriented (CRGO) silicon steel and high-conductivity copper windings. It ensures low no-load loss, reduced noise, and stable long-term operation even under varying load conditions.
Oil-immersed technology allows 200kVA smart distribution transformer to achieve both excellent insulation and efficient heat dissipation. The insulating oil acts as a cooling medium while maintaining strong dielectric performance, ensuring operational safety and reliability.

Structural Design & Key Components
Core Design
The core is of the 200kVA smart distribution transformer constructed from high-permeability CRGO silicon steel laminations with multi-step lap joints. This structure reduces magnetic losses and minimizes vibration, resulting in lower noise levels.
Winding System
The transformer adopts concentric cylindrical windings. The low-voltage winding is positioned closer to the core, while the high-voltage winding is placed externally with reinforced insulation layers. This arrangement improves insulation strength and short-circuit resistance.
Insulating Oil System
High-quality mineral oil or environmentally friendly alternatives (such as FR3) provide excellent insulation and thermal stability, ensuring consistent performance even under high load.
Tank & Sealing Structure
The corrugated steel tank is hermetically sealed, preventing moisture ingress and oil oxidation. This significantly extends the transformer's service life and reduces maintenance requirements.
