Flostar insulation adds significantly to the tensile strength of the insulated conductor through the mechanism of load transfer because the insulation has such a superior break strength.
 
   
  Our Product  
  Insulation material depends upon the electrical and mechanical properties desired and the environments. The most common material are Polyethylene and PVC.  
     
 
 
3 CORE FLAT CABLES FOR SUBMERSIBLE PUMP MOTORS

PATWARI 3 Core Flat Cables are manufactured keeping in mind the severally difficult conditions. The individual flexible conductors are made from the electrolytic grade bright copper. The wires are drawn, annealed and bunched properly. Each of these three flexible copper conductors is insulated with a specially formulated PVC compound and cores are laid-up in flat parallel position. The outer sheath of the cable is made from a very special grade of abrasion resistant PVC compound impervious to water, grease, oil etc.
