Hello, welcome to Huaxin
Power Transformer Series

S13 High Overload Capacity Distribution Transformer

The S13 High Overload Distribution Transformer is a kind of distribution transformer researched and developed to solve short-term rapid growth of power load. It mainly meets power requirements for rural public 10kV high load capacity power distribution in the operation area of State Grid Corporation, which effectively solves overload and burnout of the distribution transformer during festivals and busy farming season, guarantees safety and reliable power supply in the rural area, and meanwhile guarantees operation economy of the rural distribution transformer.

  • 1. The high overload transformer has a high tolerance in high load resistance and transformer burnout due to overload. It can continuously run for over 6 hours at 1.5 times of the rated load, over 3 hours at 1.75 times of the rated load as well as over 1 hour at 2 times of the rated load. It can effectively solve the transformer burnout problem caused by short-time high overload.

    2. The fully-sealed ripple structure is adopted for the oil tank, and the expansion coefficient is not less than 1.3, so as to guarantee no oil seepage or leakage at the specified working conditions and overload conditions.

  • 1.Specially target to occasions such as low annual average load ratio in the rural area, short-term substantial growth of load during festivals, and busy farming season. Under the premise of guaranteeing basic power capacity, it meets the demand of both long-term power usage for small load and short-term power usage with overload. 

    2. The distribution transformer with high overload capacity has the features of energy saving, high efficiency, environmental protection, small no-load current, low reactive loss, strong resistance to short circuit and more.

  • 1. Maximum temperature: +40℃/+104ºF;

    2. Maximum daily average temperature: +30℃/+86ºF;

    3. Maximum annual average temperature: +20℃/+68ºF;

    4. Minimum temperature: -45℃/-49ºF;

    5. Elevation shall not exceed 1000m;

    6. Indoor or outdoor use.

    Note: please make specific instructions in case of any special use conditions.
