Induction Electronic AVR / Stabilizer (PLR)
Induction No-Contact Oil-Immersed Electronic Automatic Voltage Regulator has durable solid mechanism and is suitable for large current load and whole plant voltage regulating environment. Conventional conductive mechanism with new cubicle design increased energy conservation and heat radiating efficiency by more than 20%. After 20-30 years service, recyclable material is higher than 90%
Specially for whole plant power equipment
No-Contact Oil-Immersed Electronic Induction Voltage Regulator (induction voltage stabilizer) has durable solid mechanism and is suitable for large current load and whole plant voltage regulating environment. Conventional conductive mechanism with new cubicle design increased energy conservation and heat radiating efficiency by more than 20%. After 20-30 years service, recyclable material is higher than 90%. For the whole plant protection, Induction Voltage Stabilizer is your best choice.
