After nearly a year's effort, the first SZ11-RL-40000/110 3D wound core power transformer was successfully produced and passed all tests conducted by national testing institutes. The important indicators are significantly better than those of traditional laminated transformers of the same capacity. After 5 years and nearly 100 million investment, HAIHONG ELECTRIC has developed a full set of intellectual property rights of 132kV 3D wound core power transformer from R&D, trial production, inspection to small batch production, and has obtained more than 30 authorized patents at home and abroad.

Product Description

Based on the high safety and low-carbon characteristics of high-voltage transformers in the power system, HAIHONG ELECTRIC has successfully developed a 3D wound core power transformer for 110kV voltage level. This product has the characteristics of low loss, low noise, low partial discharge, small radiation, small volume, etc. It has solved the bottleneck technical problem of leaping from 35kV and below distribution transformer system to 110kV power transformer system, and effectively solved the "neighbor avoidance effect "It also improves the overall economic efficiency and safety of the power transmission network.

Product Advantages

Energy saving and environmental protection

Low no load and load losses, low no-load current, low noise, low magnetic field strength of the surrounding electric field (low radiation)

Safe and reliable

Three-phase balance, high short-circuit resistance, low temperature rise, long life, low bureaucracy

High production efficiency

High precision, high efficiency, short production cycle, one time coil formation, produced by self-developed equipment

High compatibility

The radiator can be adjusted around the tank and designed to a reasonable size to meet the installation needs of different sites and easy maintenance

Comparison of Product Performance

Range Of Application

Suitable for all kinds of power transmission and distribution, especially for urban power projects where land is tight, new energy sources and comprehensive energy requirements, metallurgical industry, power generation industry, etc.
