FAQ

Certificate Collection

1. Premium Material Selection

Our transformers feature H62 high-conductivity copper rods (30% lower resistance), premium mineral oil (dielectric strength >56kV), and weather-resistant acrylic rubber gaskets. The galvanized steel enclosure (30-year rust-proof) exceeds GB standards for durability in harsh environments.

2.Digital Manufacturing

95% automated production with Baosteel silicon steel achieves:

• 50 units/day capacity (3× traditional speed)

• 5dB noise reduction

• 5% lower no-load loss

• ISO-certified vacuum oil filling/drying systems

3. Innovation and R&D advantages

National CNAS certified laboratory

Each transformer has passed more than ten rigorous tests such as lightning impulse, temperature rise, insulation no-load loss, etc. to ensure stable operation in all environments.

International mutual recognition testing standards

100% of the products have been fully tested in the laboratory, and qualified products are accompanied by global mutual recognition test reports. All products have passed CE, IEC, SGS, BV, GOST and other certifications, demonstrating professional capabilities and international credibility.

4.Product design advantages

① Ceramic bottle with groove: protects the sealing gasket from aging by ultraviolet rays, directly solving the old problem of oil leakage in traditional transformers.

② Double seal of tap changer: double insurance, no need to worry about oil leakage during installation

③ Ultra-low no-load loss: adopts step lamination process + high magnetic permeability oriented silicon steel sheet produced by Baosteel, the no-load loss is 5% lower than the national standard (GB/T 6451), and the annual operating electricity cost is significantly saved.

Applications

Utilities & Grids: Ensure stable voltage transformation for efficient long-distance transmission and safe local distribution.
Industrial Plants: Built to withstand heavy-load operations in manufacturing lines, mining sites, and large-scale processing facilities.
Renewable Energy: Seamlessly integrate with wind and solar power systems, enhancing grid stability and optimizing energy efficiency.
Critical Facilities: Guarantee uninterrupted 24/7 performance for mission-critical environments such as data centers, hospitals, and oil fields.
Urban Infrastructure: Designed with a compact footprint to meet the space and safety requirements of commercial buildings and municipal substations.
