Product Description

Product Advantages:

1. Excellent Insulation Performance

When used together with insulating paper and other insulation materials, transformer oil allows a more compact insulation structure. This helps reduce overall equipment size and manufacturing costs while maintaining high electrical reliability.

2. High Cooling Efficiency

Transformer oil transfers heat far more effectively than air, which enables rapid removal of operating heat from the core and windings. This efficient cooling capability contributes to stable performance and extends the service life of the 35kv sz1110000 kva oil transformer with oltc.

3. Strong Moisture Protection and Longer Service Life

The oil acts as a protective barrier that isolates internal insulation materials from moisture and oxygen in the atmosphere. As a result, the aging process of insulation paper is significantly slowed. It helps to extend the operational life of the 35kv sz1110000 kva oil transformer with oltc.

4. High Load Carrying Capability

The oil cooling system effectively controls temperature rise during operation. This allows the the 35kv 10000 kva oil immersed transformer to handle temporary overload conditions and meet peak power demand requirements without compromising reliability.

Despite these advantages,35kv 10000 kva oil immersed transformers also have certain limitations. Regular oil testing and maintenance are required to ensure long term performance. In addition, the presence of insulating oil introduces environmental and fire safety considerations that must be addressed through proper design, installation, and maintenance practices.

Routine Maintenance and Troubleshooting of 35kV 10000 kVA Oil Immersed Transformers

Proper maintenance of a 35kv sz1110000 kva oil transformer with oltc is essential for maintaining insulation performance and cooling efficiency. The following inspections should be carried out regularly:

1. Oil Quality Inspection

Transformer oil should be tested every six months to check dielectric loss and moisture content. If the dielectric loss value exceeds the recommended limit, the oil should be filtered or replaced to maintain reliable insulation performance.

2. Temperature Monitoring

The top oil temperature of a 35kv 10000 kva oil immersed transformer should normally remain below 85°C during operation. If the temperature rises above 95°C. It needs to inspect the cooling system for blocked radiators, faulty fans, or accumulated dust, and clean the cooling surfaces when necessary.

3. Insulation Resistance Testing

Insulation resistance should be measured at least once a year. The 35kv sz1110000 kva oil transformer with oltc is considered in good condition when the high voltage winding to ground resistance exceeds 2000 MΩ and the low voltage winding to ground resistance exceeds 500 MΩ.

4. Common Fault Investigation

If the gas relay operates, first verify that the oil level is within the normal range. After ruling out low oil level as the cause, further checks should be performed to determine whether internal gas generation or another fault has occurred.
