S11 series high voltage 110KV Oil-Immersed Type 380v electrical
Power
Transformer 6300kva 63000kva
Product Introduction
1. The iron core is made of high quality and low loss oriented cold
rolled silicon steel sheet, which
adopts two kinds of structure of three steps and five steps with
all inclined seams. There are two
advanced transverse shear lines in our factory, which can ensure
the automatic shearing of this
type of sheet, lOSS DOWN 7 ~ 10% , no-load current down more than
30% ; !
2.Oxygen-free copper wire is adopted in the coil lead, which
enlarges the use range of the layer coil
and adds axial interlayer oil channel! All products are used
three-level inspection system, that is, the
operator self-inspection, workshop inspection, Inspection, to
ensure the high quality of products;!
3.The insulating parts adopt the dense technology to ensure that
the shrinkage of the insulating parts
is minimum!
4.The advanced domestic drying system was introduced to dry the
transformer insulation
with kerosene as the medium, which can extrude the water molecules
from the deep insulation, dry
thoroughly and quickly!
5.The preheating, vacuuming and final water output of the system
are all
controlled automatically by microcomputer, the vacuum degree can
reach 6PA, and the system has
the functions of self-checking fault and cross-country diagnosis!

Main functions and features
The oxygen-free copper electromagnetic wire is adopted in the coil
lead, which enlarges
the use range of the layer coil and adds axial interlayer oil
channel. Compared with the
ordinary pancake coil, it has the following characteristics: !
A. HIGH RATE OF OCCUPATION!
B. Winding Process Simple, good processing!
C. With High Longitudinal capacitance, improve the impact of
voltage distribution, improve
the lightning resistance!
D. Because is the axial oil channel, the heat dissipation
efficiency is high!
E. Ampere turn balance is better, AXIAL MECHANICAL FORCE IS
SMALLER!
F. Using excellent radiator oil tank, not only ensure good heat
dissipation performance,
but also make the volume of the transformer greatly reduced,
beautiful shape!
