Key features

Fireproof and Safe Design: Vacuum-cast epoxy resin core with self-extinguishing properties for direct load center installation.

30-Year Expected Lifespan: Robust integrally cast coils ensure strong mechanical and short-circuit resistance for long-term use.

High Efficiency and Low Loss: Uses grain-oriented silicon steel and foil winding to achieve lower noise and loss than national standards.

50% Overload Capacity: Forced air cooling (AF) mode allows output capacity increase by up to 50% for emergency operations.

100% Humidity Resistance: Excellent moisture resistance allows operation in 100% humidity without pre-drying after shutdown.

Flexible Customization: Supports custom voltage, capacity, dimensions, and IP levels with flexible OEM/ODM services.

Renewable Energy Adaptation: Designed to handle harmonics and DC components for grid connection of energy storage systems.

Low Total Cost of Ownership: Ultra-high efficiency saves electricity costs, while maintenance-free design reduces operating expenses.

AI-Powered supplier vetting

SummaryThe supplier presents itself as a professional technical manufacturer with production equipment, standardized finished-product inspection, quality assurance, material traceability, 3D design, and broad customization capabilities. It reports OEM and ODM services and exports representing 51%–70% of total sales. However, the evidence also shows no new products in the past year, no SDK, no overseas agents, branches, warehouse, or showroom, and no participation in offline trade shows. Corrective-action and complaint-handling procedures exist but lack written records. Supplier-management controls are weak because there are no written assessment procedures or approved supplier lists, and no valid manufacturing-capacity contract with related subcontractors is reported. Financial credibility cannot be positively assessed from the provided figures, which are stated as zero for the reported periods.

Supplier typeThe supplier is explicitly identified as a professional technical supplier and reports R&D capability, 3D software design services, manufacturing equipment, and export activity of 51%–70% of total sales. These details support classification as a technical manufacturing supplier with international sales exposure.

CertificationsThe supplier states that it is certified to ISO 9001 and ISO 9002 quality management systems and claims recognition as a National High-Tech Enterprise and a Top 10 Well-Known Brand of Prefabricated Substations. The certification wording contains apparent transcription errors, so the stated certifications are evidence of claimed quality credentials but not independently verified here.

Production capacityThe supplier reports technical expertise, production facilities, advanced manufacturing processes, and equipment including machining, bending, assembly, cutting, laser cutting, welding, electrical leakage testing, and a partial-discharge lightning test laboratory. It also has inventory capability, standardized finished-product inspection instructions, and one-month average lead times in both peak and off-season periods. Nevertheless, no valid contract with related subcontractors is reported, creating a documented capacity-management concern.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, and minor customization, supported by 3D software design services and ODM capability. This demonstrates broad stated customization coverage.
