Resin-Insulated Dry Type Power Transformer
0102030405
Non-encapsulated Class H Dry Transformer
The SG (B) 10 non-encapsulated Class H dry transformer is an insulation system based on insulating paper. Excellent electrical and mechanical properties are maintained throughout the service life of the transformer. The insulation paper is not easy to age, the shrink resistant agent is anti-compression, and the elasticity is very strong, so it can ensure that the coil of the transformer remains tight in structure even after several years of use, and can withstand the pressure of short circuit.
Main StructureHeg
1. The iron core is a stepping 45° full diagonal joint
2, inter-turn, inter-layer, inter-section insulation and insulation cylinder are composed of insulating paper or molded parts
3. The low-voltage coil is foil type
4. The high voltage coil is continuous
5, the body adopts special barrier and noise reduction measures
High Voltage CoilHeg
The high voltage coil adopts a continuous structure with high mechanical strength and good heat dissipation condition. The coil is wound on the molded insulating cylinder, and the flat copper wire covered by insulated paper is used as conductor. The insulation material between layers is used as insulating paper. Thus improve the reliability of product operation; Excellent moisture-proof performance, more able to withstand thermal shock, never crack, local discharge capacity <5Pc, easy to decompose and recycle after life, protect the environment.
Low Voltage CoilHeg
The low-voltage coil is a foil-wound structure, the coil is wound by high-quality copper foil and H-class insulation material, and the insulation paper is used as the insulation system between layers. The coil is impregnated into a solid whole by VPI vacuum pressure.
1. The coil has high mechanical strength and strong short-circuit resistance.
2, coil thermal shock resistance is strong, product life is improved.
3, coil "moisture, dust, salt spray" ability is strong.
Iron CoreHeg
The core material is 0.2mm thick high quality high permeability silicon steel sheet 45° full diagonal lap, and the core is non-punching and tensile plate structure; The surface is coated with insulating paint, moisture-proof and rust-proof, low loss and low noise. The operating noise is about 16db lower than the national standard, which can meet the noise requirements of national first-class residential areas.
