  6. Description of content : The notified draft Ecuadorian Technical Regulation establishes 
the requirements to be met by power transformers immersed in PCB (polychlorinated 
biphenyl) -free insul ating fluid and dry -type transformers, prior to the marketing of 
domestic and imported products, with the aim of protecting human safety and the 
environment and preventing deceptive practices.  
The notified Technical Regulation applies to the following prod ucts: 
• Single -phase and three -phase power transformers, immersed in insulating fluid  
• Single -phase and three -phase power transformers, dry type  
It does not apply to the following transformers:  
• Single -phase transformers with rated power less than 1 kVA and three -phase 
transformers less than 5 kVA  
• Transformers which have no windings with rated voltage higher than 1,000 V  
• Instrument transformers  
• Traction transformers mounted on rolling stock  
• Starting transformers  
• Testing transformers  
• Welding transformers  
• Explosion -proof and mining transformers  
• Transformers for deep water (submerged) applications  
• Single -phase and three -phase distribution transformers covered by Ecuadorian 
Technical Regulation RTE INEN 141
