Vacuum-Cast Epoxy Resin Insulation System: Windings are encapsulated with high-grade glass fiber-reinforced epoxy resin under vacuum, forming a dense, robust insulating layer that effectively resists moisture, dust, and contaminants.
High Fire Resistance Rating: Compliant with international and national standards such as IEC 60076-11 and GB 1094.11, achieving Class F1 fire resistance (no toxic gas emission). Suitable for applications with stringent fire safety requirements (e.g., high-rise buildings, subways, hospitals, data centers).
Maintenance-Free Operation: Oil-free, leak-proof, non-flammable, eliminating risks of explosion and environmental contamination, ensuring safety for personnel and equipment.
Low Losses, High Efficiency: Featuring high-permeability silicon steel or optional amorphous alloy cores, combined with optimized magnetic circuit and winding design, significantly reducing no-load and load losses. Complies with GB 20052 Energy Efficiency Class 1 and international high-efficiency standards (e.g., DOE, CQC), substantially lowering operational costs.
Low Temperature Rise, Long Service Life: Scientific thermal design coupled with the excellent heat dissipation properties of epoxy resin ensures low winding temperature rise and uniform hotspot distribution, with an expected lifespan exceeding 30 years.
Eco-Friendly Materials: Resin materials are recyclable, and no harmful substances are emitted during production or operation, supporting green grid initiatives.
High Protection Rating: Standard IP20 enclosure (higher ratings such as IP23, IP45 available) effectively prevents ingress of solid objects and water droplets, suitable for harsh environments (humid, dusty, saline, etc.).
Strong Short-Circuit Withstand Capability: The cured resin forms a solid bond with copper conductors, creating a high-strength integrated structure capable of withstanding significant electromagnetic forces and exhibiting excellent short-circuit resistance.
Low-Noise Design: Optimized core clamping, vibration damping, and noise-reducing resin properties ensure operational noise levels below national standards, ideal for noise-sensitive areas.
Electrical Parameter Customization: Tailored to customer requirements, including voltage ratings (up to 35kV), vector groups (e.g., Dyn11, Yyn0), impedance voltage, tapping ranges, etc.
Structural & Installation Customization: Available in cabinet-type, open-type, or enclosed configurations (with auxiliary systems like temperature control and fans). Flexible design options for installation methods (floor-mounted, rail-mounted, wall-mounted), cable entry/exit positions, and terminal types.
Special Application Customization: Enhanced designs for specific conditions such as photovoltaic/wind power integration, rail transit, marine power, mining explosion-proof applications, and high harmonic environments (e.g., rectifiers, variable frequency drives), featuring reinforced insulation, harmonic resistance, high overload capacity, and anti-condensation measures.
