Haihong Electric Low Temperature Rise Substation Upgrade Solution

When the transformer in the substation fails to meet energy efficiency requirements, or experiences issues such as overheating, excessive losses, or insufficient load capacity, must the entire substation be replaced? Not necessarily!

From the perspective of user economic benefits and resource utilization, Haihong Electric offers a low-carbon, environmentally friendly solution—the Low Temperature Rise substations Upgrade Solution. This approach avoids wasteful extensive dismantling and replacement, focusing instead on precise upgrades. It effectively addresses problems like high losses and high temperature rise in substations, enhancing both performance and safety reliability, thereby revitalizing the original substation with new energy.

Achieve More with Less Investment

·         Lower Costs: There is no need to dismantle the old substation or replan installation. Simply replace the original transformer directly, making it more cost-effective than a full cabinet replacement.

·         Significant Economic Benefits: After the upgrade, the transformer operates with a lower temperature rise and improved heat dissipation efficiency by over 30%*¹, resulting in high energy efficiency and reduced electricity costs.

Quick upgrade, Minimal Impact

·         Completed in One Day, Simple and Efficient: The upgrade can be quickly accomplished, compatible with most conventional substations. No additional space is required, and it is ready for immediate use, minimizing the impact of power outages.

Stable Operation, High Safety and Reliability

·         Low Temperature Rise Operation: Significantly reduces the operating temperature rise of the original substation, minimizing insulation aging and short-circuit risks caused by high temperatures, while also reducing load losses.

·         Strong Overload Capacity: Capable of steadily handling impact loads such as power usage peaks, equipment startups, and ultra-high load operations over the long term, without causing cracks in the transformer coil insulation.

·         Safer and More Durable: The Fully Insulated Open Ventilated 3D Wound Core Dry-type Transformer reduces combustible material weight by approximately 85%*², offering advantages in fire and explosion prevention. It also has enhanced short-circuit resistance.

Energy Saving and Environmental Protection

·         Improved Energy Efficiency: The Fully Insulated Open Ventilated 3D Wound Core Dry-type Transformer operates with lower losses, reduced leakage magnetism, and minimal stray losses. Combined with the self-developed zero-carbon vortex flow scalable cooling system, it significantly enhances the energy efficiency of the entire substation.

·         Environmentally Friendly: The transformer features a green design throughout its lifecycle, with operational noise below 45 decibels and a 50% reduction in surrounding electric and magnetic fields*³, highlighting its green characteristics.

Haihong Electric's Low Temperature Rise substations Upgrade Solution actively supports the national "Dual Carbon" strategic goals. It upgrades original substations from "prone to overheating" to "high-load resistant with low temperature rise" in a low-carbon, low-cost manner, once again driving the green and low-carbon transformation of power equipment with innovative technology. Haihong Electric consistently aligns with national strategies, addresses practical user needs, practices green development concepts, and contributes professional expertise to achieving high-quality economic social development and the "Dual Carbon" goals.
