Haihong Electric Delivers Its Answer to the "New Starting Point for Energy Conservation" in the Transformer Industry

During the recently concluded 2026 National Energy Conservation Promotion Week, Haihong Electric held in-depth exchanges with multiple institutions. From three perspectives – end users, design institutes, and engineering installation contractors – the enterprise explored one core question: what truly makes the energy-saving 3D Wound Core Transformer technology a "new starting point"?

3D Wound Core Technology Balances Stable Operation and Energy Efficiency to Meet Power Distribution Demands of High-Efficiency Enterprises

In the past, manufacturing enterprises prioritized basic functionality when selecting transformers, with energy efficiency as a secondary consideration. Today, energy conservation has become an indispensable requirement. The Implementation Plan for High-Quality Development of Energy-Saving Equipment (2026–2028) explicitly mandates that energy-saving equipment including transformers shall reach internationally leading energy efficiency levels. The Circular on Launching a Three-Year Campaign to Advance Energy Conservation and Carbon Reduction Renovation in Key Industries categorizes power transformers as key energy-consuming equipment subject to strict supervision. Haihong’s 3D wound core technology perfectly addresses the era’s demand for China’s industrial energy transition from "basic functionality" to "ultra-high efficiency".

Featuring a 3D wound core structure paired with circular coils, the transformer bears uniform mechanical stress and delivers even temperature distribution, endowing it with robust structural durability. Under equivalent cost configurations, its no-load loss is cut by 30%, no-load current reduced by 70%, and load loss lowered by 5%, slashing annual operating costs by 10% and generating substantial electricity bill savings.

Haihong’s 3D Wound Core Transformer technology has gained recognition from numerous large enterprises. In mid-June, as a special technical partner, Haihong Electric visited multiple manufacturers. Faced with harsh operating conditions typical of high-energy-consumption industries – concentrated loads, continuous operation and heavy impact loads – the company put forward its core viewpoint: the new starting point for energy-saving transformers lies in reliable performance and remarkable cost savings.

Fully-Insulated Low-Temperature-Rise 3D Wound Core Dry-Type Transformer with Cooling System Facilitates Streamlined Design and Outstanding Project Performance

The demand of end users – "stable performance and cost savings" – translates into specific technical parameters for engineers at design institutes. While meeting client requirements, designers must also weigh equipment safety, reliability and economic efficiency. On June 11, Haihong Electric was invited to Dongguan Electric Power Design Institute and presented an innovative, cost-effective product: the Fully-Insulated Low-Temperature-Rise 3D Wound Core Dry-Type Transformer with Cooling System. Built with inherent fireproof, explosion-proof, moisture-resistant and anti-pollution capabilities alongside crack-proof coil insulation, this product integrates two core innovative technologies to precisely address key concerns of design engineers:

1.Full insulation design covering the core and the entire unit. The core withstands 30kV voltage resistance to eliminate risks of high-voltage ground breakdown. The robust structure delivers superior impact resistance and eradicates discharge hazards from clamping components.

2.Zero-carbon eddy current pressurized cooling system. Full-load temperature rise is far below national standard limits. Lower temperature rise reduces load loss, drastically slows insulation aging and significantly extends equipment service life. Notably, future load expansion only requires upgrading the pressurized flow guide without replacing the entire transformer body, greatly cutting renovation and upgrade expenses.

When selecting transformer models, design institutes need solutions that simultaneously satisfy long-term capacity margin, cost performance and service life alongside energy efficiency requirements. The Fully-Insulated Low-Temperature-Rise 3D Wound Core Dry-Type Transformer with Cooling System empowers electrical engineers to raise the overall performance benchmark for energy-saving transformers at the design stage. Its technical achievements won high praise from Dongguan Electric Power Design Institute, with multiple designers acknowledging its exceptional performance and expressing willingness to cooperate on upcoming projects.

Balanced Energy-Saving Performance and Installation Convenience Ease Work for Construction Contractors

All equipment specified by design institutes relies on installation contractors for on-site assembly. Even with excellent energy-saving indicators, complex installation and cumbersome maintenance will diminish practical value during engineering implementation. On June 13, Haihong Electric visited Guangdong Rong’an to elaborate on the advanced merits of the Fully-Insulated Low-Temperature-Rise 3D Wound Core Dry-Type Transformer with Cooling System.

Developed with transportation, installation and maintenance friendliness as core design priorities, this transformer boasts a compact, lightweight structure for easy installation. Its lightweight top-mounted pressurized flow guide simplifies assembly work, while the integrated protective enclosure balances protection and operability. Multiple access windows enable convenient maintenance and safeguard operators’ workplace safety. Crafted with premium materials for stable operation, the equipment drastically reduces routine inspection frequency, delivering dual "energy savings" in both labor and material inputs. During the exchange, the team from Guangdong Rong’an commended the integrated enclosure design for its thoughtful consideration of construction convenience. For power installation partners across the industry, this holistic advantage embodies the full connotation of the "new starting point" of 3D wound core energy-saving technology.

Over the past week, Haihong Electric completed a full closed-loop promotion of its energy-saving technology value chain by engaging three key stakeholders: end users, design institutes and construction & maintenance contractors. Superior low energy consumption alone cannot define technological advancement. A true "new starting point for energy conservation" must integrate energy efficiency, safe stable operation, full-lifecycle cost-effectiveness and hassle-free construction & maintenance.

Since its founding, Haihong Electric has adhered to its philosophy of Genuineness · Honesty · Sincerity and focused on one single mission: continuously upgrading the performance of energy-saving transformers to eliminate waste of electricity, cut power expenses for end users, and boost industry practitioners’ confidence in equipment selection. Upholding internationally leading 3D wound core technology, Haihong Electric consistently supports sustained improvements in energy efficiency across national power distribution systems.
