Isolating transformers are used in Air Field Lighting system and provide isolation between the primary high voltage series circuit and low voltage secondary circuit. The primary of all transformers are connected in series and fed by constant current regulator . secondary feeds the individual Airport Runway light.

Isolating Transformers are used to maintain continuity of high voltage primary circuit incase one or more lamps are not in working order and to maintain the supply of 20 Amps. From the 6.6 amps.series circuit or vice - versa alternatively to suppl 6.6 Amps. From 8.3Amps . in the series circuit .

The Toroidal magnetic core made from cold rolled silicon steel, grain orienred lamination of low loss quality . The core is insulated by nylon cap or polyster paper .

 
     
  The primary and secondary windings are of standard quality super enamailed copper wire .  
     
 

The primary is a single core made from annealed, tinned , copper wire, EPR insulated and PCP sheathed, suitable for 5000V operations .One secondary, cable end is moulded with plug and other with receptacle as per Customers ,s requirement

 
     
 

The secondary is two core made of annealed , tinned , copper wire, ERP insulated and PCP sheathed . Theb secondary cable end is moulded with receptacle as per reqirement of the customers .

 
     
  The isolating transformer is epoxy casted and cured under vaccum.  
 

The Epoxy casted assembly is rubber moulded to with - stand outdoor exposure , immersion in water or direct burial in earth containing concentration of oil, acids and alkalies .
