Dry type transformerSGB(H)10 series environmental friendly dry-type on-load transformer of class 6-10kv
  • Product overview
  • Apply
  • Specifications
  • Technical
Insulation system of SGZB10 adopts the insulation materials   from DuPont, maintain excellent electrical and mechanical performance through out the whole lifespan of transformer. products are anti-aging, anti-shrinkage and anti-compression, coupled with an exceptionally strong elastic, the coil still keep compact and withstand short-circuit pressure after several years of operation. High safety, no combustible resin, no poisonous gas, no combustion support.

● Volume and weight of unit KVA is decreased.
● Increased emergency overload capacity.
● Convenient repair and maintenance 
● Low noise 
● Insensitive to humidity, dust or pollution.
● No partial discharge or crack during running.
● Flexible design, customization according to your requirements is available.
● Installation height: altitude shall not exceed 1000m;
● Waveform of source voltage is approximate to sine wave;
● Symmetry of multi-phase source voltage: 
   connected voltage of multi-phase transformer should be symmetrical approximately.
● Ambient temperature: 
   Max temperature +40℃
   Max daily mean air temperature: +30℃ 
   Max annual mean air temperature: +20℃
   Min air temperature: -30℃ (applicable for indoor transformers)
