GNEE New Material cast resin type transformer
63 KVA Dry Type Transformer is safe, flame-retardant and fire-proof, and can be installed directly in the load center. Maintenance-free and easy to install. It has good moisture-proof performance and can be put into operation without pre-drying after shutdown. It has low loss, low partial discharge, low noise, and can operate at 120% rated load under forced air cooling conditions. We have a complete temperature protection control system to provide reliable guarantee for the safe operation of the transformer.

SCB13 63 KVA Dry Type Transformer Material List
|
Material name |
Material |
Quality Characteristics |
|
Silicon steel sheet |
Brand new high-quality grain-oriented high magnetic permeability cold-rolled silicon steel sheet |
Cold-rolled silicon steel strip has the advantages of small size and light weight when used to make transformers due to its high magnetic permeability and low loss. |
|
Coil |
Copper |
The copper content is 99.9%. The state stipulates that the copper purity used by electricians must be above 99.5%. Brass can be used in small power non-power transformers, and its use is unqualified and illegal. In addition, using brass as a transformer coil will increase copper loss (load loss) and reduce the power of the transformer. |

|
Insulating oil |
Naphthenic mineral oil |
Clean and transparent liquid, free of sediment, suspended mechanical impurities and cotton-like substances. The presence of inferior oil or secondary oil accelerates the aging of the transformer, makes it loud, prone to short-circuit and burnout, and has a short service life. |
|
Insulating paper |
Kraft paper/NOMEX insulation paper |
Insulating paper is an important part of the transformer. One of the main reasons for the aging and burnout of the transformer is the use of inferior insulating paper, which is prone to arc breakdown and shortens its service life. |
|
Epoxy resin |
High epoxy value (>40) 6101 epoxy resin |
F/H grade temperature resistance 155℃/180℃. Technical indicators such as temperature resistance, pressure resistance, hardness, shrinkage, water absorption, glass transition temperature, bonding strength, and tensile strength are very critical to the insulation and pouring quality of dry-type transformers. |
|
Electrical wood |
beech trees |
Strong insulation ability and high tensile strength. |
Dry Transformer Feature
1. The coil is wound with copper wire or foil, reinforced with glass fiber, and epoxy resin is vacuum dried, degassed, and dehumidified without fillers and cast as a whole. It has high mechanical strength, short circuit resistance, and strong impact resistance.
2. The first end of the high-voltage winding and the middle tap adopt a copper embedded embedded structure, which has good rigidity, facilitates gear adjustment, and is beautiful and neat.
3. The iron core is made of high-quality grain-oriented cold-rolled silicon steel sheets, with 4-degree fully inclined multi-step joints. The surface is covered with resin insulating coating, which is moisture-resistant, rust-proof and noise-reducing.
4. Elastic parts are used to clamp the iron core, clamps and coils to keep the coils in a stable and compressed state to reduce noise.
5. The transformer is designed to be self-cooling. A longitudinal ventilation channel is reserved inside the wall of the integrally cast high (low) voltage coil barrel. It can be equipped with a forced air cooling device (cooling fan). After using the forced air cooling device, the output capacity can be increased by 20 %.
6. Equipped with a temperature controller, place a platinum resistor (Pt100) in the pre-embedded hole on the top of the low-voltage coil. It monitors the temperature rise of the transformer winding, automatically starts and stops the cooling fan, and has fault alarm, over-temperature alarm and over-temperature trip functions to provide a reliable overload protection device for the dry-type transformer, thereby improving the safety of the dry-type transformer operation.
