High Voltage Oil Immersed Distribution Transformers, Manufacturer of Distribution Transformer, 10kv Oil Power Transforme
S11-M series fully sealed oil-immersed power transformer has the advantages of low loss, low noise and high efficiency, which can achieve good energy saving effect and reduce pollution. Compared with ordinary oil-immersed transformers, the fully sealed transformers eliminate the oil storage cabinet. The change of oil volume is automatically adjusted and compensated by the elasticity of the corrugated sheet of the corrugated oil tank. The transformer is isolated from the air to prevent and slow down the deterioration of the oil and the insulation aging. , to enhance operational reliability, maintenance-free maintenance.
Product Features:
1. Magnetic Core
The three-limb iron core is made of oblique cut Grain-oriented, seven-step silicon steel lamination insulated on both sides, guaranteeing low losses and low noise. These values are even improved by laser treatment. It is protected on the surface with a flash-proof varnish in order to prevent the sheet from corrosion and to reduce the noise.
2. The winding
The winding as the centerpiece of the transformer must be especially protected – both against high electrical stress due to external overvoltage and against mechanical overloads by short circuits. Varelen transformers are systematically designed to meet these requirements. The windings are made of copper or aluminum. Low-voltage windings are made of strip or flat wire, and the high voltage windings are manufactured from round or profile wire. (“diamond-dotted paper”) bonds the winding into a compact block while drying and increases the short-circuit capacity additionally.
3. The Tank Whether during transport or operation –the tank must be absolutely tight under mechanical stress. Preconditions to achieve this are constructional experience, the most modern calculation methods, and high-quality welding work. Special attention is paid to corrosion protection. Pretreatment of the surface is processed by phosphating pickling, contributes to corrosion protection, just like multi-coating with preset drying times for each layer. On request, hot-dip galvanization provides for even better protection.
4. Dielectric liquids
Mineral oil /Dimethyl silicone/ vegetable oil(FR3 oil).
