QYDJ/TDM series oil-immersed light test transformer
0.0 0.0
Product description

The QYDJ/TDM series of oil-immersed test transformers is a series of test transformers developed and produced after a lot of improvements on the basis of the original similar products according to the "Test Transformer" standard. This product complies with DL/T848.2-2004 "General Technology for High Voltage Test Equipment" Conditions-Part 2: Power Frequency High Voltage Test Device", a new type of product developed and produced. This series of products have the characteristics of small size, light weight, compact structure, complete functions, strong versatility and convenient use. Oil-immersed test transformers are particularly suitable for power systems, industrial and mining enterprises, scientific research departments, etc. to conduct insulation strength tests under power frequency or DC high voltage on various high-voltage electrical equipment, electrical components, and insulating materials. It is an indispensable important equipment in high voltage test.

Product Features

1. The product is pressed into a high-pressure casing at one time;

2. The complete isolation between the casing and the oil barrel and all the connecting parts are sealed with imported oil-resistant O-ring seals, which completely solves the common transformer oil leakage problem;

3. The design of sleeping iron core effectively improves the shock resistance of the product;

4. All products undergo a 24-hour inversion test before leaving the factory to inspect and test the problem of oil leakage in the transformer;

5. All products can pass the 1.1 times induction withstand voltage test;

6. The insulating oil adopts colorless and transparent Karamay original oil;

7. The high and low voltage line adopts high-strength polyester, oxygen-free copper rod enameled wire;

8. The iron core is made of new WISCO di-silicon cold-rolled silicon steel coils.
