Description
66kV oil-immersed power transformer core is made of high-qualityoriented silicon steel sheets stacked in multiple steps, and the surface iscoated with curing paint. It has the characteristics of low loss and lownoise.
Features:
1. The coil adopts the inner and outer strut struicture,and the high-strength cardboard tube structure is used between the coil and the ironcore and between the coils,which effectively guarantees the ability ofshort-circuit resistance.
2. The wall of the fuel tank adopts a one-time forming and bending corrugated structure, which increases the mechanical strength of the fuel tank and has a beautiful and generous appearance.
3. A omni-directional positioning structure is adopted between the body and the fuel tank to ensure the stability of product transportation and operation.
4. Apply to power plant (station), substation (power distribution stations) and industrial etc.
5. Perfect quality guarantee system: The company strictly controls the quality of products according to ISO19001 standard.
6. To meet the client’s needs, we can provide products of other voltage ratios, Vector Groups, and rated capacities, as listed in the table.
