High Reliability Power Distribution Transformer With Reasonable Accessories Selection


Power Distribution Transformer Main Functions and Features


1 High reliability, advanced level of performances, reasonable economical indicators.

2 The core joints are of stepped shape with 3 steps, and the surface of the core is coated with cured paint to lower losses and noise.

3 The winding has novel structure and its oil passage is reasonable designed. Its newly designed insulation structure helps enhance its mechanical strength and the short circuit withstanding ability.

4 The oil tank is in various types, all have good outlook.


Power Distribution Transformer Characteristics

  1. To improve insulation level by Electric field strength calculation program
  2. To improve winding short circuit ability by high frequency welding technology
  3. To increase winding short circuit strength by hydrant pressing technology
  4. To reduce noise level by core hydrant pressing technology
  5. Adopting High quality seals and special design to prevent oil leakage

Pay attention to the follows while transporting:

l Weight, size, hanging height, etc. can be found in the reference drawings.

l If flatbed truck is used for transporting, should check its loading record in the past.

l Fix the transformer body on the flatbed truck with rope through fixing holes. Refer to reference drawings for the locations of those holes.

l Attention! There is special axis for hanging and pedestal for hoisting jack. Use them while hanging and carrying the transformer, no use with other places.

l The ropes must be long enough to ensure the hanging angle is less than 30 degrees. Balance girder should be used due to limit of space height.

l Only the special holes can be used while the transformer is being haled. No for ramp with gradient over 15 degrees or speed exceed 20km/h.
