Product Description

Potential Voltage Transformers

Outdoor Type Potential Transformers (With Top Tank)

Macroplast manufactures Potential transformers with top tank (expansion chamber) up to 132 Kv system voltage.

This design has two tanks. The core and windings are contained in the lower tank. The primary winding is taken through the HT insulator to be connected to the primary terminal arranged on the top tank. The secondary windings are connected to secondary terminals placed on the lower tank. In this design, the Top Tank provides space for expansion of Oil.

Construction Features :

  • Primary Terminal
  • Oil Level Indicator
  • Pressure Release Device
  • Oil Expansion Tank
  • Bushing
  • Bushing Clamp
  • Secondary Terminal Box
  • Main Tank (3 mm thk)
  • Name & Rating Plate
  • Earthing Terminal
  • Lifting Lug
  • Oil Filling Plug
  • Oil Drain Plug
