Product Description

Introduction:
Transmission and distribution system from distant power plants will be delivered to the user by adjusting the
electrical energy transmitted through high voltage transmission lines, and substations buck after a few levels to
suit the user. Located near the end-users of electricity distribution transformers reduce the voltage to a suitable
final value. The voltage is reduced to electrical equipment operating voltage transformer called distribution
transformers, transformers such as power plants with a daily lighting and generally low-to 0.4kV and below.
Distribution transformer capacity is small, generally in 2500 kVA and below; once the voltage is lower, in 35 kV
and below. Unlike ordinary oil-immersed transformers, I produced a sealed distribution transformer conservator
removed from the main body of the fin corrugated tank as the heat expansion and contraction components,
transformer oil and the atmosphere is completely isolated. Including the transfer capacity of distribution
transformers and dual voltage transformers and distribution transformers. Yung tune with the size of the
transformer is a two-capacity, and can be adjusted according to load size distribution transformers. Changing
the high voltage winding connection methods, and low-voltage winding series of conversion as well as the
adjustment of the tap without excitation by a special tone volume switch is complete. Meanwhile, large-capacity
transfer small capacity, low pressure due to the increased number of turns, the core flux density significantly
reduced, leaving the smaller loss silicon steel unit, load loss and no-load current is also reduced, to Energy
Conservation purposes. Dual voltage distribution transformer is a kind of size of the two voltages, and can be
adjusted according to the grid voltage distribution transformers. High voltage winding and the series of
transformations, and then adjust each sub-section of the non-excited by a special switch is complete.

 

Features:
Distribution transformers using CAD design, performance in line with IEC60076, GB1094, GB/T6451 standards.
Distribution transformer cores made of cold rolled grain oriented silicon steel core by the German GEOGE
automatic production line applications company ladder seams (Step-Lap) process. Distribution transformer tank
of corrugated tank, the tank by the German company GEOGE automatic production line manufacturing, surface
pre-treatment solution and powder coating are used in international brand products, tank production line by
automatic degreasing, pickling, phosphating, electrophoretic pre-treatment spray powder, and then high
temperature curing, the appearance of anti-corrosion ability transformer. Distribution transformer coils made of
high strength wire (or paper covered wire) wound,Ampere-turns distribution, rational insulation structure, with a
strong anti-short circuit capability. Distribution Transformer body using free hanging core structure, seals made
of high quality acrylic rubber, can effectively prevent photo-aging, thermal aging.
