(1)For the transformer whose capacity is 500kV and below, the on-load loss value above diagonal line is suitable for Dyn11 connection, and the value below diagonal line is suitable for Yyn0 connection.

(2)Overall dimensions are for reference only, and we have a right to change it.

(3)We can produce transformers with special performance parameter according to requirements of users.

Weite, established in 1988, is one of the leading and professional 10kv s11 three-phase full-sealing oil-immersed distribution transformer manufacturers and suppliers in China. Equipped with advanced equipment and technology, our factory can offer you safe, quality and durable transformer with reliable performance.

Performance and characteristic of 10kV and S11 type transformer:

Comparing with general oil-immersed power transformer, the full-sealing power transformer cancels conservator, and uses fin plate of corrugated tank as heat dissipation components.

The fin plate can expands as the volume of transformer oil to isolating internal transformer from external atmosphere for avoiding degradation, moistened insulation and aging.

The core adopting high quality cold silicon sheet improves flux density condition in core and reduces sound and loss.

The winding adopting high strength enameled wire(or paper covered wire) and cylindrical structure with uniform ampere-turn and reasonable insulation structure has a strong capacity of anti-short circuit.

All of the fasteners adopt check nut to insure that they are not loose during operation after long distance transportation. The transformer whose surface of tank adopts 3-proofing (coating of damp proof, mould proof and salt spry proof) after parkerizinis is widely used in some nasty conditions such as metallurgy, mine and petrochemical.
