Power Transformer (35kV) Oil-immersed Transformer Products structure and technical features The oil-immersed transformer produced by our factory have these advantages: low loss, low noise, high short circuit strength and good appearance. We company create these prefect products of that each parameter has reached to advanced level among domestic similar products by combining advanced manufacture equipments and technology. Structure features: Core and main body: it is used iron core cutting line ,all inclined ladder joints and improving flux trend to eliminate flux saturation phenomenon of iron core in joints . By doing these, it reduces the no-load loss, no-load current and noise of transformers. Adopting pulling-plank structure, in order to strengthen the ability of withstanding short-circuit, we put many nails around pressing planks and bracing plates are used as support between H.V and L.V yoke, make the iron core be a whole. The iron core sheet are coated by glue which are specialized for silicon steel , so that all silicon steels can be bonded together to make the iron core be  integral one, this effectively enhances mechanical strength and plays a positive role in the core anti-rust. The low part of the body and the oil tank are supported through bracing plates adopt" high intensity electric laminated" technology, to guarantee the low part of oil-immersed transformer's body safe and reliable. Coil: The high-voltage(HV) coil adopts an interleaved-continuous structure, The low-voltage(LV) coil adopts an interleaved-continuous or spiral structure, are independently provided with voltage-regulating winding to balance the ampere turn of each winding-up, effectively lower the mechanical force to minimal level.

Advantages of toroidal transformers 1. High efficiency and high performance price ratio Toroidal core has good electromagnetic performance, like high saturation magnetic flux density, high primary inductance and large unit magnetizing power capacity, which improve the utilization ratio of the core and the winding window area, and reduce the number of turns and the direct current resistance, and also greatly improve the overload capacity and load efficiency of the toroidal transformer. Based on these conditions, the product design does not need to consider more power margin and heat dissipation conditions, and also effectively control the cost. 2. Excellent no-load characteristics Toroidal core is wound with high permeability silicon steels, no gap on magnetic circuit, low magnetic resistance. Under the same power and magnetic field density, the no-load loss and exciting current of toroidal transformer are only 50%~70% of other transformers, which reduce the standby loss and improve the equipment operation reliability. 3. Low noise There is no gap of toroidal core, the silicon steels are tightly winded, and after the vacuum impregnation with pressure it becomes a whole. Even in the middle, high magnetic frequency, it will not cause noise due to magnetic expansion. This is what the EI, dry-type and other lamination cores cannot match. 4. Low magnetic flux leakage, low leakage inductance Toroidal core has a high saturation flux density, and the coil is uniformly distributed on the core, magnetic potential difference can effectively reduce the magnetic leakage. Normally, with the same transformer specifications, the magnetic flux leakage of toroidal transformer is only 1/10 of the EI one. The main coil is tightly and rationally layered winded, and then the leakage inductance of the primary and secondary coils can be better coupled to reduce the primary and secondary leakage inductance. 5. Safety of electrical structure There is a certain thickness of stacked dielectric film between the core and primary coils, primary coil and electrostatic shielding, electrostatic shielding and secondary coil, secondary coil and the installation plate, which completely isolates the electrical gap and is safe without maintenance. Therefore, isolated toroidal transformers have been widely used in medical equipment transformers.
