The 100kVA dry-type transformer adopts efficient dry-type insulation technology and is designed for industrial, commercial and residential power systems. With its excellent performance and compact structure, the transformer provides stable and reliable power support and is suitable for small and medium-sized power distribution needs. Through strict quality control, NPC ELECTRIC's 100kVA dry-type transformer provides users with high-quality, low-maintenance power solutions.
The 100kVA Dry Type Transformer is a high-performance, safe, and environmentally friendly distribution transformer designed for medium and low voltage power distribution applications. It is widely used in commercial buildings, industrial facilities, renewable energy systems, data centers, hospitals, and infrastructure projects where safety, reliability, and low maintenance operation are essential.
Unlike traditional oil immersed transformers, the 100kVA dry type transformer adopts an epoxy resin cast insulation system, eliminating the need for transformer oil and significantly reducing fire risks and environmental concerns. This makes it an ideal choice for indoor substations, high-rise buildings, underground facilities, and locations with strict safety requirements.
The transformer is manufactured with a high-quality grain-oriented silicon steel core and optimized magnetic circuit design. The advanced core structure effectively reduces no-load losses, improves energy efficiency, minimizes operating noise, and ensures stable performance during continuous operation.
The winding system adopts high-quality copper or aluminum conductors with advanced casting technology. The epoxy resin encapsulated winding provides excellent insulation strength, high mechanical stability, and strong resistance to moisture, dust, and temperature fluctuations. This design improves short-circuit resistance and ensures reliable operation under different load conditions.
The 100kVA dry type transformer uses an efficient air cooling system (AN/AF) to maintain proper operating temperature. Its compact structure, excellent heat dissipation performance, and flexible installation design allow it to operate reliably in various indoor environments with limited space.
During manufacturing, every transformer undergoes strict quality control from raw material inspection, core assembly, winding production, resin casting, assembly, and final testing. Before shipment, each unit is tested according to international requirements, including insulation resistance testing, winding resistance testing, voltage ratio testing, no-load loss testing, load loss testing, dielectric strength testing, and temperature rise testing.
With its outstanding safety performance, energy efficiency, and long service life, the 100kVA Dry Type Transformer provides a reliable power distribution solution for modern electrical systems.
