Features & Advantages


Core:


The core is manufactured with high quality cold rolled grain-oriented silicon steel of high magnetic conductivity, and 45° mitring and steps overlapping structure is used for core production, thus to effectively reduce no-load loss and no-load current.

HV winding:


HV winding is manufactured with high quality copper conductor, adopting optimized structure to improve electric distribution. Lightning impulse wave process is carried out for calculation and analysis, thus to improve transformer's anti-lightning impulse capability.

LVwinding:


LV winding is manufactured with high quality foil conductor, so the ampere-turn balance is excellent and the transverse magnetic flux leakage is low. The anti-short circuit capability is thus greatly improved. Oil conduit is rationally designed in the windings to increase winding's heat dispersion surface, effectively reduce temperature and improve transformer's overload capability.


Insulation Structure:


The transformer adopts class-A insulation. The HV and LV windings are arranged in concentric way. Between the windings are oil-clapboard insulation structure built with paper cylinder and small oil conduit.

Tank:


The tank is jointed with high-quality steel. Rust-removing and phosphorization processes are carried out for the tank surface, then the surface is coated with FVC anti- erosion paint, thus to effectively prevent grease pollution and chemical erosion. The appearance is nice and harmonic with the environment. The whole structure is easy for installation and maintenance. It can be widely applied in outdoor environment and under harsh conditions.

Accessories:


The transformer is equipped with HV & LV bushings, oil drain valve, earthing bolt, lifting board, rating plate, pressure relief valve and other accessories. Transformers of over 800kVA power are equipped with signaling thermometer and gas relay.

 


Executed Standards:
IEC60076

 

Package

1 Disassembly

 

With reference to the detail list, disassemble the equipment. During the disassembly, pay attention to the followings:

l All the oil in the disassembled parts have been drained off

l Some of the oil in tank should also be drained away. (normally 100~150mm under the cover) The weight of oil to be drained away is marked in the transportation drawing.

l The openings formed during unpacking should be sealed with gaskets and cover

l Any more, please refer to the “Instruction of the OLTC transformer for testing, transportation and storage”.

l Fill the tank with dry nitrogen gas while draining oil. And then seal the tank.

l For transformer with wheels, the wheels should be taken down.

 

2 Packing

 

l The oil, which is drained or to be added, should be put into clean and sealed cans.

l Transformer body will be exposed for transporting.

l The largest size and weight of transport parts may be found in the transportation drawing.

l All the unpacked parts are packed with firm wooden boxes.

l On each package there are marks as follows:

--User name

--Pieces number

--Gross weight

--Net weight

--Manufacturer

l The contents of each package are shown in its packing list.

l Enough spare surface repairing lacquer is equipped with the transformer, for repairing the damage of surface lacquer during transportation.

l There is a crash recorder on the wall or cover of the box.
