PRESSED STEEL RADIATORS

Range:

  • 300 Wider
  • 520 Super

Application: Pressed Steel Radiators are both used in Power transformers and Distribution Transformers.
Features:

The new circular embossing introduced enables the transformer oil to be distributed across the radiator at any level which results in even heat dissipation over the total width of the element thus improving the heat dissipation and efficiency in comparison with the radiator types available in the market.

CORRUGATED TANKS

Features:

  • We are manufacturing Corrugated Wall Panels from CRCA Steel Sheets in thickness ranging between 1.2 to 1.4 mm.
  • Corrugated Wall Panels are formed in length ranging from 500 to 1100 mm, with depth of 50 to 400 mm and pitch of 40 to 60mm.
  • The Corrugated Tanks are constructed using Mild Steel Sheets/Plates in thickness ranging between 3 mm to 10 mm.

Advantage:

  • Compact in size.
  • Saving in Steel/Reduction in weight of transformer tanks.
  • Saving in oil. Additional reduction in oil volume because of more stability in corrugation (no bulging of corrugation).
  • Saving Freight cost.
  • Improve heat dissipation.
  • Oil cleaning easier and less expensive.
  • Elegant appearance and Hermetically sealed construction.
  • Due to vertical oil channel greater stability is achieved in comparison with the old system. It means tanks can withstand a higher degree of pressure than before

Comparison :

  • Transformer Size :   630 KVA
  • Ambient Temperature :   45 deg C
  • Heat Dissipation :    4.89 kW
