runthala industries  covers a wide range of oil filled power and distribution transformers with the off circuit tap changer conforming to the international standards of quality and safety. These transformers are designed and developed using the latest technology and provided with a variety of terminations so as to suit the requirements for any new installation or replacement.  optimum efficiency is ensured by delicate proportioning of core and winding losses using crgo m3 to m5 moh lamination, electrolytic grade copper with transposition in l.v. Coil for current sharing in parallel conductors, electric grade press paper, boards and mineral oil. Thus a better regulation is achieved resulting in a longer life. Careful designing also reduces the noise level to the minimum.    standard fittings : rating & diagram plate - earthing terminals lifting lugs - thermometer pocket oil conservator with drain plug - air release hole with plug oil level indicator - explosion vent oil temperature indicator - drain –cum-bottom-filter valve silica gel breather - cable box on l.t.

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.  Applications 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. 

• voltages433 V, 3.3 kV, 6.6 kV, 11 kV, 22 kV, 33 kV

AC Transformer's coil is manufactured from a heavy copper tubing. It is designed and tuned to the inverter circuit which applies a medium frequency (generally 500 Hz or 1000 Hz) voltage to the Induction coil. The magnetic field produced by the induction coil induces eddy currents in the charge and heats it. Medium frequency is necessary to enhance the rate of heat generation.
