Product Description

Introduction

Based on up-to-the-minute technology and high grade quality material, the mentioned 3 phase isolation transformer lists a number of benefits such as easy maintenance and damp proofing. These advantages can be easily applied to distribution places and power transmission lines such as tall buildings, wharfs, tunnels, stations, underground railways, enterprises, airports and many more. The offered transformer is widely used in the occasions that require voltage less than 500V and AC current ranging from 50 to 60 Hz.

Customization

We can also design and produce group of connections, voltage for input and output and tapped winding capacity as per the customers' requirement.

Below cited are the working conditions of three-phase isolation transformer:

  • Various factors such as chemical deposition, dirt, gas, dust, steam may have serious affect on the insulation of transformer, thus the environment should be free of all these.

  • Altitude and relative humidity should be less than 1000 meters and 90 percent, respectively.

  • It requires ambient temperature ranging from -15 to +40 degree Celsius.

  • User may negotiate, in case any special working condition is present in the list.

Bulletined below are the main technical characters:

  • The rated input and output voltage are ±10% and +1% (without any load), respectively.

  • Breakdown does not occur for one minute, under the frequency of 2000V sine voltage

  • Capable of bearing overload for a minute having twice flow of rated current

  • Input and output voltage along with current can be easily indicated

  • Available without any additional distortion of waveform

  • Efficiency is 96% and resistance of insulation is 50M

  • Protection from over flow of current

  • Can be automatically operated without the need of attendant

  • Power may range from 250 to 5kW
