Dry-type transformer specifications Main structure 1. The core is a step-type 45° full-bevel joint 2. Inter-turn, inter-layer, inter-segment insulation and insulation tubes are all used Insulation paper or molded parts 3. Low-voltage coil is foil type 4. High-voltage coil is continuous type 5. The body adopts special isolation and noise reduction measures
High-voltage coil High-voltage coil adopts a continuous structure with high mechanical strength and good heat dissipation conditions. The coil is wound on a molded insulating cylinder.
High-voltage coil uses insulating paper wrapped flat copper wire as conductor, and insulating paper is used between layers. The coil is impregnated into a solid whole by VPI vacuum pressure, avoiding the shortcomings of high interlayer voltage, poor heat dissipation, easy thermal breakdown, and low mechanical strength of multi-layer cylindrical coils, thereby improving the reliability of product operation; excellent moisture-proof performance, better able to withstand thermal shock, never crack, partial discharge <5Pc, easy to decompose and recycle after life, and protect the environment.
Low-voltage coil Low-voltage coil is a foil-wound structure. The coil is wound with high-quality copper foil and H-grade insulating material. The interlayer uses
Low-voltage coil insulating paper as the insulation system. The coil is impregnated into a solid whole by VPI vacuum pressure. Product structure features: 1. The coil has high mechanical strength and strong short-circuit resistance. 2. The coil has strong resistance to thermal shock and the product life is improved. 3. The coil has strong “moisture-proof, dust-proof and salt-fog-proof” capabilities.
The core material is made of 0.2mm thick high-quality high-magnetic conductivity silicon steel sheet with 45° full oblique overlap. The core adopts non-punching,
The core pull plate structure; the surface is coated with insulating paint, which is moisture-proof and rust-proof, with low loss and low noise. The operating noise is about 16db lower than the national standard, which can meet the national first-level residential area noise requirements.
