1. Low Noise Level: The 160kva oil filled low loss electrical transformer features a compact design and employs new materials and advanced manufacturing processes to effectively reduce operational noise. It is designed without a conservator, which results in a lower overall height compared to conventional units of the same class.
2. Advanced Vacuum Filling Process: During the sealing process, a vacuum oil filling technique is applied to completely eliminate moisture inside the transformer tank. Once sealed, the internal components are not exposed to air. This effectively prevents oxygen and moisture from entering the unit, which would otherwise lead to the degradation of insulation performance, which includes the aging of insulating materials and the dielectric oil.
3. Extended and Reliable Service Life: The tank cover and tank flange of the fully sealed 160kva oil filled low loss electrical transformers are connected using bolts or a welded structure. This design completely isolates the insulating oil from contact with the air, which prevents the insulation from absorbing moisture. As a result, the rate of insulation aging is greatly reduced, significantly extending the operational lifespan of the 160kva oil filled low loss electrical transformer.
4. Compact Size and Aesthetic Appearance: The 160kva oil filled low loss electrical transformer tank utilizes corrugated fin type cooling panels. These panels adjust to oil volume changes caused by temperature fluctuations through their elastic expansion and contraction. The corrugated tank design offers a visually appealing, compact shape and requires a smaller installation footprint.

A. The oil level shall be maintained between one quarter and three quarters of the oil level gauge scale. An oil level that is too low may lead to insufficient insulation or overheating. An oil level that is too high may cause abnormal oil pressure.
B. The inspection method involves observing the oil level through a transparent oil level gauge or a magnetic oil level gauge. The inspection of a 160kva oil filled low loss electrical transformer must be carried out with the power outage and stable oil temperature. During winter, the oil level may drop by five to ten percent.
A. Sampling for testing shall be conducted at least once per year. The test shall measure the breakdown voltage which must be at least 35 kilovolts, the moisture content which must not exceed 20 parts per million, and the acid value which must not exceed 0.1 milligram of KOH per gram. If these values exceed the specified limits, the oil must be filtered or replaced.
B. The oil replacement cycle is typically eight to ten years, subject to adjustment based on the specific operating environment.
A. The top oil temperature shall not exceed 85 degrees Celsius for natural cooling or 95 degrees Celsius for forced cooling. The temperature rise limit is 55 Kelvin.
B. Dust and debris on the surface of the radiator shall be cleaned regularly to ensure proper ventilation.
