Strict full lifecycle management is implemented for insulating mineral oils, covering procurement, operation and maintenance, testing, and disposal. Its standard documents clearly specify the limit values for dozens of key indicators of in-service oil, including dielectric strength, water content, acid value, particle contamination, and dissolved gas analysis. This means that oil purification machine is not just tools for post-fault repair, but essential equipment for preventive maintenance and condition-based inspection, used to restore degraded oil indicators to compliance, thereby extending transformer life and reducing replacement costs.

Practical application and verification effects: from on-site repair to oil regeneration

In South Africa, the application of Transformer Oil Purification System has surpassed simple filtration, showing features of multifunctional integration and mobile on-site operations.

On-site dehydration, degassing, and purification are the most typical applications of oil purification machine in South Africa. Measured results show that processed transformer oil has water content reduced to below 5 ppm, impurity filtration accuracy at 3 ppm, and gas content meeting IEC standards. This directly addresses insulation hazards caused by oil deterioration and significantly reduces equipment downtime and maintenance costs.

Due to South Africa's vast geographical features and on-site maintenance needs, trailer-mounted mobile oil purifiers are favored. ACore Filtration Co., Ltd customized the MTP series Mobile Transformer Oil Purification Machine for South African customers, with rainproof and dustproof features, allowing rapid transfer between remote substations. These devices integrate vacuum drying, vacuum oil filling, and hot oil circulation, and can even function as independent vacuum units to perform vacuum treatment on the transformer body, achieving “one machine, multiple functions” on-site comprehensive operations.

In addition, the application scenarios extend to oil regeneration and the circular economy field. Acore Filtration Co., Ltd has exported multifunctional regenerative Mobile Transformer Oil Purification Machine to customers in South Africa's renewable energy sector, used to purify and recycle insulating oil that is not completely decommissioned, rather than simply discarding it, which aligns with South Africa's environmental protection and resource recycling needs.
