Specification:

1. Meba Autotransformer SG series High voltage winding is pie winding and has hierarchical structure; low voltage winding is pie winding and has foil structure.

2. The winding are open ventilating, so the windings have a fine the heat radiating performance. Adopt good vacuum-impregnation technique, thus improve the damp-proof performance.

3. The transformer possesses 180 insulation system; C-220-NOMEX paper is adopted as the main insulation layer of transformer; thus the transformer possesses high overload ability.

4. X/R structure is adopted for the parameter design of winding; thus reduce the stroke current when the burst short-circuit happens.

5. The temperature rise of winding adopts 125K temperature rise standard.

Working conditions:

1.Ambient temperature: -15°C~+40°C
2.Altitude: <1000m
3.Relative humidity: <90%
4.Environment exists without gas, steam, chemical deposition, dust or dirt that will affect transformer’s insulation seriously, also explosive or corrosive medium is not allowed.
5.If any special working conditions that are not in line with the above stipulations, user shall negotiate with us.
