110kV Oil-immersed type power transformer
General :
Adopting advanced and strictly technology, the 110kV's transformer that we develops to produce index all achieves the advanced standard of international by way of constantly exploring and make perfect. The product possesses characteristics such as the low loss, low noise and low power in part and the resisted short circuit ability is strong etc. The product breed is diversified and the model specifications complete.
The transformer product can be installed and use in outdoor or indoor, and it is very ideal equipment in the distribution network in factory, rural area and city.
Features:
4.1 Short-circuit capability
The use of advanced computer program for calculating the transformer short-circuit conditions, analysis of the coil short-circuit conditions in various parts of the force and deformation. Transformer short circuit capacity can be greatly improved.
4.2 low loss
Optimization of electromagnetic calculations, using a variety of ways to effectively control the leakage magnetic shielding to reduce the load loss and to avoid overheating.
High quality cold-rolled silicon steel lattice orientation of high permeability, the use of miter joints STEP step, no holes are not stacked on the yoke process, reduce the load loss, load current, electromagnetic noise.
4.3 high mechanical strength
Six-side positioning of the body using methods to meet the transport direction of the acceleration level is not greater than 0.3G, the vertical direction is not greater than 0.15g.
