MAIN TECHNICAL PARAMETERS

Product Selling Points

1.Fully Sealed & Maintenance-Free Core Design: Integral fully sealed construction with high-performance sealing materials eliminates oil aging and moisture ingress, reducing maintenance frequency by over 90% compared with traditional open-type transformers.
2.Ultra-High Efficiency & Low Loss: Adopts low-loss silicon steel sheets and full-copper windings, with no-load loss reduced by 30% and load loss optimized by 25% against national energy efficiency Grade 1 standards, cutting long-term power consumption significantly.
3.Wide Voltage Compatibility: Supports 6/6.3/6.6/10/10.5/11kV high-voltage input and 0.4kV low-voltage output, with ±5%/±2×2.5% tap adjustment, adapting to 95% of industrial power grid voltage fluctuation scenarios.
4.IP54 Protection & Harsh Environment Adaptability: Dust-proof, water-proof, and anti-corrosion performance enables stable operation in high-dust (≥80mg/m³), high-humidity (RH≥95%), and corrosive gas environments, solving the pain point of unstable operation of conventional transformers in harsh conditions.

Operation and Maintenance Cost Optimization

1.Minimal Daily Maintenance Costs: The fully sealed structure isolates insulating oil from air, avoiding oxidation and emulsification; oil sample testing is only required every 5–8 years (no oil change for qualified oil), saving the cost of oil replacement and manual operation (about $500–$1000 per oil change for conventional transformers).
2.Reduced Energy Consumption Costs：For a 1000kVA model, the annual energy saving is about 8,000 kWh under 80% load rate, translating to an annual electricity cost saving of $800–$1,200 (based on industrial electricity price of $0.1–$0.15/kWh).
3.Lower Fault and Replacement Costs：Reduces the frequency of equipment replacement, avoiding the capital cost of transformer procurement and installation every 10–15 years for conventional products.

Logistics and Installation

1.Convenient Transportation：Reasonable layout of internal components and optimized external dimensions make the product easy to load and unload; the whole machine is fixed with anti-shock brackets, and the tank is equipped with lifting lugs and forklift slots, suitable for road, sea, and railway transportation.
2.Simple and Fast Installation：All transformers are fully debugged in the factory (including voltage adjustment, insulation testing, and no-load test), and can be put into operation only by on-site wiring and fixed installation, reducing on-site debugging time by over 70% (installation can be completed within 4–8 hours for a single standard model).
3.Comprehensive On-Site Support：For large-capacity models (≥800kVA) or key project customers, we send professional technical engineers to the site to provide one-to-one installation guidance, including foundation inspection, wiring debugging, and commissioning acceptance.

Durability and Stability

1.Reliable Operation in Diverse Environments: Fully sealed structure prevents dust from entering the internal core and windings; the external shell is designed with dust-proof gaps, ensuring normal heat dissipation while avoiding dust accumulation, and can operate stably in metallurgy and textile workshops with dust concentration ≥80mg/m³ for a long time.
2.Excellent Anti-Loss and Anti-Aging Performance：High-quality cold-rolled oriented silicon steel sheets with low iron loss and high-purity oxygen-free copper windings have excellent thermal stability and electrical conductivity, and the insulation system uses H-class insulating materials (temperature resistance 180℃), effectively resisting thermal aging caused by long-term operation.
3.Ultra-High Operational Stability：The product has a no-load operation stability test of ≥1000 hours and a full-load continuous operation test of ≥500 hours in the factory, with no abnormal temperature rise, noise, or vibration (noise ≤55dB at 1m distance).

Production Process Advantages

1.Advanced Manufacturing and Precision Processing Technology:Adopts CNC shearing and folding, step-by-step lamination, and vacuum annealing processes, with the core lamination gap ≤0.05mm, reducing iron loss by 15% and improving magnetic conductivity significantly.
2.Strict and Comprehensive Quality Control System:We have established a full-process quality control system covering raw material procurement, production processing, product assembly, and finished product testing, in accordance with ISO9001 quality management system standards, with 16 quality inspection links and 3 full-inspection nodes:
3. Key Core Technology Advantages:Our R&D team has independent intellectual property rights for the electromagnetic design of the transformer, optimizing the core and winding layout through finite element simulation analysis, realizing the optimal matching of loss and volume.
