Basic Info

Model No.: FG-S13RL Series

Product Description

The three-phase coils are arranged in a "pin" shape, forming a central gas passage between the coils, which is connected to the center. The "smoke chimney" generates strong air convection due to the temperature difference of 30-40 °C between the upper and lower iron yokes. The cold air flows from below to The central passage is supplemented, and heat is radiated from the inner inclined surface of the upper iron yoke, and the heat generated by the transformer is quickly taken away in the natural circulation. The FGI S13 series eaton transformers usa with top quality and great service has several high performance features including 75 kva transformer amperage, line loss deduction: the no-load current is reduced by more than 90%; Ultra-quiet: the noise is reduced by 10-15 decibels; No interference: the magnetic flux leakage is reduced by more than 50%; Raw materials saving: the cost of copper and iron is reduced by 20%-30%; Significant economic benefits: the cost of ten years of substation is down 17.2% from the distribution transformer specification sheet.

Coil Core Oil Filled Transformer

Structure Characteristics

Iron core: the material performance is not lower than 30ZH120 cold-rolled silicon steel sheet; the three-phase three-column three-dimensional symmetric structure has the most balanced three-phase magnetic circuit; each group (roll) chip is wound by a thin steel strip on a special core winding machine. The pressure is even and firm; the core frame is vacuum annealed to eliminate stress and improve electromagnetic performance; the surface of the core is coated with epoxy paint, moisture proof and solidified.

Winding: paper-coated copper flat wire made of low-oxygen copper or QQ-2 acetal enamelled round copper wire; low-voltage coil is double-layer or four-layer round copper or new spiral, or foil type. The high-voltage coil is a multi-layer cylinder; the coil oil passage is corrugated, the interlayer insulation is double-sided adhesive paper; the low-pressure and high-pressure surfaces are coated with epoxy semi-adhesive glass fiber belt to increase mechanical strength.

Body and lead: Insulating cardboard is used to make upper and lower iron yoke insulation; laminated wood is used to make balance pad insulation; laminated paper is used as lead support; all fasteners are effective locking locknuts.

Oil tank: Fully sealed corrugated oil tank with triangular structure, corrugated sheets are provided in three phases to ensure heat dissipation and compensate for the expansion and contraction volume of oil volume change with oil temperature change; oil level gauge with pressure relief valve on the cover surface is convenient refueling and observing the oil level, and releasing pressure safety protection against sudden fault overvoltage inside the oil filled water cooled transformer.

Performance Features

1. Energy saving: the no-load loss is reduced by 40%-50%, and the load loss is reduced by 7%-10%;

2. Reduce line loss: the no-load current is reduced by more than 90%;

3. Ultra-quiet: the noise is reduced by 10-15 decibels;

4. No interference: the magnetic flux leakage is reduced by more than 50%;
5. Saving raw materials: the cost of copper and iron is reduced by 20%-30%;
6. Significant economic benefits: The cost of ten years of substation is down 17.2% from the generation oil filled transformers.

Storage Instructions

When the oil filled transformer is stored, the oil level of the fully sealed transformer should be kept 2~3cm below the cover, and the storage condition should be checked regularly. For the transformer to be transported by the oil conservator, the oil conservator must be installed to ensure a certain amount of oil pressure and oil, to meet the needs of its temperature change, and the seal of the three phase distribution transformers must be protected during storage.
