1 Introduction


Oil-immersed type transformer features low noise, low loss, rational structure, high quality material, scientific design, strict production technology and advanced test method. The product also has the following additional advantages:



2 Structure



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.


LV winding is manufactured with high quality foil conductor


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.


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 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.


3  Inspection and Acceptance

On receiving the transformer, please check immediately the product type and other specifications with reference to the rated plate on the transformer, to determine they conform to the requirements written in the contract. Meanwhile, please check the technical documents and attachments by referring to the shipping list. For transformer itself, please check the following items:


1) Whether there are oil-leakage from the transformer tank.


2) Whether the transformer or its attachment are damaged.


3) Whether the wearing parts are damaged, for example, the pressure relief valve, thermometer, bushing,

gas relay and multi-function tube-type oil-level indicator.


Note: in normal cases, a transformer with rated power lower than 630kVA is not equipped with signal thermometer and a hermetically sealed transformer with rated power higher than 800kVA is equipped with gas relay and signal thermometer.


4  Storage

For storage before equipment installation, the oil level should reach the oil tank or above. Please check regularly the storage conditions. For transformer with oil-reservoir dismantled during transportation and the storage time will be at least half a year, the oil-reservoir must be mounted, thus to ensure certain oil-pressure and sufficient oil in the tank and to adapt to the temperature variations.
