Transformer Oil Purification Systems Present and future transformer ratings require high quality and high purity insulating oils at the point ofuse. The increasing voltage and rating of the modern transformer and electrical apparatus results in greater electrical stress in insulating material andfluids. To handle these greater stresses, oils with better dielectric qualitiesare required. Also lower residual water content in insulating fluids andmaterial must be maintained.
The proper treatment and upgrading of the insulating fluid will result inthe improvement of the properties of the entire insulating media of powertransformers.
The principal functions of the insulating fluid are to serve as adielectric material and as an effective coolant. To perform these functions,the insulating fluid must have the necessary qualities at the time of initial
impregnation and filling at the factory and later maintain the same quality inthe field operation.
Qianneng’s ZJA series transformer oil purification system upgrades the new or used electrical insulating fluids including transformer oils, polybutenes and silicone fluids. These systems and equipment were developed as a result of 24 years of experience in vacuum treatment of electric insulating fluids.
