    Sc (B) 10-100~2500 /10kv H-Class Insulation Three-Phase Dry-Type Transformer

    Product Description

    Sc (B) 10-100~2500 /10
    H-Class Insulation Three-Phase Dry-Type Transformer

    Our company has developed this product by ourselves. As a high performance, high safety, pollution free dry-type transformer, it is suitable for the harsh environments where there is a high fire protection requirement, the great load fluctuation and the site where is of filth and moisture. For example: Airport, power plant, metallurgy operation, hospital, high building, shopping center, densely inhabited area, petrochemical industry, nuclear power station and nuclear submarine, etc.

    Nominal service conditions:
    1. A unique ceramic type of insulation structure is adopted in H-class high strength insulation cylinders and high-frequency ceramic cushion blocks are adopted to ensure that no deformation will occur.
    2. The high-voltage and low-voltage windings are made of NOMEX wrapped flat copper wires and imported copper foils. And they are sealed with high strength insulation materials.
    3. The iron core is made of laminated imported high-quality silicon-steel sheets of high magnetic conductivity with a 45 stepwise all-bias structure. A flexible fastening unit is adopted to fasten the winding and iron core, which ensures a relatively low no-load loss and low noise.
    4. Outlet terminals are fixed to the top of winding, taps are in the middle of winding, low-voltage line terminal are in plate-type current-conducting rows for which cold pressure welding is adopted.

    Normal service conditions
    1) Altitude should not be over 1000m: Indoor type
    2) Highest ambient temperature should not over: +40C; Highest daily average should not over temperature: +30C
    3) Highest annual average temperature should not over: +20C, lowest temperature should not below -5C
    We can provide transformer operated in special conditions according to use's requirement.

    Applicable standards
    GB6450-1986 Dry-type power transformer
    GB4208-1993 Casing protection grade (IP code)
    GB/T10228-1997 Technical parameters and requirements for dry-type power transformer
    GB/T17211-1998 Guide rules for dry-type power transformer load
    GB10237-1998 Insulation level and insulation test for power transformer
    GB4208-1993 Casing protection grade (IP code)
    JB/10008-1999 6~220KV transformer sound level
    JB/T56009-1998 Product quality grading for dry-type power transformer

    Performance Characteristics:
    1. Excellent heat dissipation, long thermal life, good overload capacity, without forced air-cooling under a long-term 120% overload and IP45 condition. It can operate for a long time at full load.
    2. Extremely high safety fire resistance performance, smoke-free while burning under a temperature as high as 800C.
    3. Extremely high thermal shock resistance capacity.
    4.100% water-proof, excellent moisture-proof.
    5. Unique winding structure and field strength calculation makes partial discharge impossible.
    6. Low loss and significant energy saving effect. Compared with SC9 series of dry-type transformers, the no-load loss falls 10% and load loss falls 5% in average.
    7. The insulation material and copper conductor can be dismantled easily and recycled after the service lift. Therefore, no pollution will occur.
