Under the Dual Carbon Goals and National Large-Scale Equipment Renewal Policy, the Wave of Energy-Efficient Transformer Upgrades Emerges

HAIHONG Electric Co., Ltd. aligns with national green development initiatives by developing safe, highly reliable, energy-saving, environmentally friendly, and quiet green power distribution products. We provide superior technology, products, and services to support large-scale transformer equipment upgrades.

Superior Technology | Revolutionizing Century-Old Structures: 3D Wound Core Redefines Energy Efficiency Standards

The 3D Wound Core technology fundamentally transforms the traditional planar core transformer structure that has existed for over a century, offering innovative, safe, and highly reliable solutions for transformer efficiency and noise reduction.

Leap in Energy Efficiency:

No-load loss reduced by 30%, load loss by 5%, and no-load current by 70% (compared to silicon steel laminated cores).No-load loss of amorphous alloy 3D Wound Core reduces  by over 70% (vs. silicon steel laminated cores).

Quiet & Eco-Friendly:

Operational noise reduced by 10-25 dB (vs. laminated core transformers). Open ventilated 3D Wound Core dry-type transformers have successfully resolved noise pollution issues in multiple locations. Electric and magnetic field intensity around the core is 50% lower than laminated core transformers.

Space Revolution:Open ventilated  3D Wound Core dry-type transformers are 28% smaller in volume and 44% lighter in weight compared to cast resin dry-type transformers with silicon steel laminated cores of the same capacity.

Superior Products | Full Coverage for Power Distribution Scenarios, Empowering Smart Cities and Rural Vitalization

Open Ventilated  3D Wound Core Dry-Type Transformer: The "Green Heart" for Outdated Power System Upgrades

Addresses high energy consumption and insufficient capacity in manufacturing parks, commercial complexes, residential areas, and rural outdoor oil-immersed transformer applications.

Energy Efficiency Breakthrough:

If 100,000 SCB9 laminated core dry-type transformers (avg. capacity: 800kVA) are replaced with SGB14 open-type 3D Wound Core dry-type transformers, annual savings would include:610,000 tons of standard coal 1.08 million tons of CO₂ and 60,000 tons of SO₂ emissions reduced.

Capacity Upgrade Without Space Expansion:

Example: A large new energy manufacturer replaced a 1,600 kVA laminated core transformer with a 2,500 kVA open ventilated  3D Wound Core transformer in the same footprint.

Outdoor Adaptability:

Directly replaces outdoor oil-immersed transformers at low cost, improving power distribution quality and safety.

Smart Enhancement:

Equipped with HAIHONG’s intelligent energy-saving monitoring system for digital operation and maintenance.

Miniaturized Double-layer Prefabricated Substation: Compact Power Distribution Solution

Solves power facility upgrade challenges in urban villages, old districts, and rural areas with limited land resources.

Space-Saving Design:

45% smaller footprint, with ultra-compact models reducing space by 60% (vs. conventional single-layer substations).

Enhanced Safety & Reliability:

Features open ventilated 3D Wound Core dry-type transformers for improved fire and explosion resistance.

Corrosion-resistant enclosure.

Incorporates the zero-carbon pressurized vortex retractable cooling system with self-developed patented technology for superior heat dissipation.

Doubled Capacity:

Upper layer can accommodate two open ventilated 3D Wound Core transformers, doubling capacity while reducing footprint by 80% (vs. two single-layer substations, including foundation space).
