We manufacture and export technologically advanced transformers with OLTC in India, which ensures trouble free performances. It is a load tap changer. Its major function is to change the voltage level of the secondary winding to maintain the constant voltage. OLTC Transformer keeps the voltage constant within the limits.
Airen Power covers A wide range of oil filled distribution transformer with on Load Tap-changer (Upto 10 MVA in 11 KV And 33 KV Class) confirming To the international Standard Of Quality and safety.These transformers are designed and developed using latest technologies and can be provided with A variety of termination so as to suit the requirement of new installation or replacement.optimum efficency is ensured by delicate preparation of core and winding losses using CRGO M3 –M O H lamination ,electrolytic grade 99.9% pure Copper, with transposition in LV coil for current sharing in parallel conductors ,electric grade press paper,board and mineral oil. careful designing also reduce noise level-2 minimum.
