Main characteristics of S13 coil core transformer

4.2 Winding
The use of low-oxygen copper paper-covered copper flat wire or QQ-2 acetal enamelled round copper wire; The low voltage coil is double or four layer round copper type or new screw type or foil type. The high voltage coil is multi-layer cylinder type; The coil oil passage is of corrugated structure, and the insulation between layers is double-sided dotting paper. The low pressure and high pressure surfaces are wrapped with epoxy resin semi-viscous glass fiber tape to increase mechanical strength.

4.3 Body and lead
The upper and lower iron yoke insulation is made of insulating cardboard; Laminated wood as a balance pad insulation; Laminated cardboard is used as lead support; All fasteners are effectively locked locknuts.

4.4 Fuel Tank
The triangular structure of the fully sealed corrugated oil tank is adopted. The three phases are provided with corrugated sheets to ensure heat dissipation and compensate for the change of oil volume due to the change of oil temperature. An oil level gauge with pressure relief valve is installed on the cover of the tank to facilitate refueling and observation of the oil level height, and to protect the release of pressure in case of sudden fault overvoltage in the transformer.
