VPI Dry Type Power and Distribution  Transformers with OLTC  VPI Dry Type Power and Distribution Transformers with OLTC
(VPI Transformer with On Load Tap Changer)
RANGE : Upto 5000 KVA in 11 KV Class.

RUNTHALA INDUSTRIES offers a technologically advanced range of Dry Type VPI (Vacuum Pressure Impregnated) Transformers with an On Load Tap Changer (up to 5000 KVA in 11 KV Class)using CRGO M3 to M5 MOH Lamination and Electrolytic Grade copper. These transformers are designed for trouble-free performance confirming to IS – 2026 with a lower power loss and lesser noise. Modern manufacturing techniques coupled with optimum utilization of active materials ensure cost effectiveness, reliability and a long trouble-free performance.
RUNTHALA INDUSTRIES Dry Type Transformers are fitted with enclosure for Indoor installations. It is an eco-efficient product using no oil,making handling easier and also minimising the chance of spillages, leakage and nontoxic smoke emission. Use of Class ‘F’/‘H’ insulation increases the heat bearing capacity a.

Fire avoidance and environmental safety are the key aspects to keep in check. Therefore, the substitution of oil filled transformers in dry type variety is one of the most important steps to attain it. VPI Dry Type Transformers are used when located near any load centre or a fire hazardous place. Special type of fire resistant insulation is used for the windings, thereby minimising the risk of catching fire.
