Overload Oil Immersed Transformer 20 KV - 2000 KVA Safety Energy Saving Transformer

20kV - 2000kVA , Oil - Immersed Transformer, Three Phases, Two Winding, Power Distribution


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:


1. High mechanic strength, great anti-short circuit capability, excellent anti-lightning impulse capability and high reliability. All these performance indexes rank first in the industry in China.


2. Excellent overload capability, capable of continuously working under 110% rated load.


3. Low loss, energy-saving, economic and maintenance free.


4. Nice appearance, small size, less installation space occupation and low engineering cost.


5. Each performance index and technical specification excels that specified in China GB, international IEC and industrial standards.


6. Hermetically sealed corrugated tank structure is adopted, thus to effectively prevent air corrosion to the oil and prolong service lifetime of the transformer.

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:


This series products is applied for oil-immersed enclosed type transformer.It is

mornted on the cover of the oil tank and indicates the oil level inside.When the

window at the top part of the oil Gauge gives blue color,it means the oil level is

normal,oil elvel is above the oil tank cover;


Otherwise it will indicate abnormal when red color appears and it means the oil level is under the tank cover,oil must be refilled. M40×1.5 screws at the top of the Oil-level Indicator act as the interface for

oil-filling connecting bube,pressure relief-valve vacuum extraction.
