QJA Series Ultra-High Voltage Oil Treatment Equipment

Mainly used for the purification of the insulating oil, remove the water, gas and mechanical impurities, so as to improve the compression strength of insulating oil and oil products quality, ensure the safe operation of high voltage electrical equipment.  Ensure the oil up to use general standard after processing. It is the preferred oil filtering equipment of the power industry.


1. Used in uhv construction installation of electricity transmission &transformation facilities equipment, maintenance and overhaul.

2. Used for capacitor,  transformer, ultra-high voltage transformer oil purification treatment depth

3. Transformer oil compensating function

4. Used for transformer in circulation dry processing

5. Realized transformer vacuum, vacuum oiling

6. With double level design of the high vacuum at high altitude areas use this series models more advantages


High efficiency in dewater and degassing: Adopting Dingneng's latest patented technology of three-dimensional evaporation degassing, dehydration system, the unique stainless steel folding of swirling separation tower, increasing the separation area makes the oil film. Built-in secondary evaporation interlayer, plus a special vacuum packing, increase the oil film contact area, rapid moisture in the separation of oil and gas, efficiency is the several times of similar products.

Powerful ability in remove impurity: High β precision filter material, multistage filtering and encryption step by step. And remove oil within the tiny impurity. Filter volume is big, pollutant carrying capacity is big. Service life is long, and configure the filter pollution automatic detection function.

Short oil processing time: Double-stage high vacuum large pumping speed, can quickly and efficiently remove the moisture in the oil, the oil dry degree, breakdown voltage value, disposable filter effects are greatly improved, shorten oil processing period, so as to improve the performance of the oil.

Uniform Heating: The system adopts low density indirect cycle carbon fiber heating technology, put an end to produce acetylene gas oil cracking. Low energy consumption, uniform heating, the oil temperature is stable.

Automatic control: the machine adopts automatic constant temperature control, photoelectric liquid level control, automatic antifoaming control, automatic pressure protection and excellent configuration, ensure no spray equipment in operation of oil, the safe and stable operation

Interlock protection: overload protection, overpressure alarm outage protection, short of oil, oil protection, phase sequence protection to ensure the machine run reliably for a long time

Humanized instructions: automation design, and the oil temperature, pressure, vacuum, filter pollution, running state and other instructions.

Modern design: Advanced net oil process design, online processing and offline processing, high degree of automation, which can realize the unattended operation. The equipment compact structure, convenient movement.

Good comprehensive performance: Low noise, easy operation and maintenance interval long, low energy consumption and low cost, high oil filter efficiency, etc.
