Capacity:- We manufacture Automatic Voltage Controllers of 30KVA to 3000 KVA

We are manufacturing Industrial type Automatic Voltage Regulators (Stabilizers/Rectifiers) using the differential wound Vertical Roller Type Regulators. Manufacturing LINEAR TYPE +/- Heavy Duty Regulators with rollers rolling on both the sides of the coil. The Actual Efficiency of our stabilizer in running conditions at 100% Load for the (360-460 V) model will be 99.5% in comparison to less than approx. 95-96% of conventional type stabilizer for the Automatic Voltage Controller of similar rating.

 

Advantage

By installing voltage controller, you can save 10% to 20% power consumption of lamps, tube etc. and reduce its failure rate up to 80% if you are having higher voltage problems. It has been observed that the industries usually face the problem of both low as well as high voltage problem. With the installation of AVC and by maintaining 400/230 volts three/single phase – you will certainly achieve the advantages as explained under: 

»

Reduction in Breakdown of Electrical Equipments: 60-80% depending upon the input voltage ariation and working hours of the plant.

»

Energy Saving: 5-10% depending upon the input voltage variation and working hours of the plant.

»

Reduction in MDI: There will be definite reduction by 10 -15% after the installation of the equipment.

»

Improvement in Power Factor: There will be definite improvement in the power factor by 10-15% after the installation of the equipment.

»

Uniform Quality of end product.

»

Better Utilization of Existing Transformer and cables.

»

Lesser production loss and better efficiency of plant.

»

Depreciation allowance @80% as per Income Tax Act.

Quality

CORE - The core will be constructed from low loss, cold rolled, grain oriented, annealled laminations of electrical sheet steel conforming to the latest internationals standards using grade 4 laminations with lamination thickness from 0.24mm to 0.27mm for the minimum no laod and load losses

WINDINGS -Coils will be wounded with 4- DPC paper layer covered plus 3 polyster film cover for better insulation with Electrolytic grade copper strip and taking current density of 2 to 2.5 amps/mm2 in oil accordingly we use more copper than any other manufacturer to give the highest quality with minimum losses for the entire running life of the equipment. Radiators Cooling is provided to keep the hot spot temp. as low as possible for higher working efficiency for all the years with lowest temperature rise even on full load conditions.
TANKS & PAINTS - The acoustic enclosure/tanks will be made of sand blasted M.S. steel plated / sheets of 3 mm thickness with adequate bracing & stiffners. All the external surfaces are given a primary coat of 2 Pack Epoxy primer and finishing two coat of Epoxy paint for better life with chemical treatment inside with seven tank paint procedure for the effective protection of the enclosure while woking in the toughest of the chemical and mositure zones
OIL - Oil will be tested for resistivity, dielectric and acidic charactristic conforming to IS 335. Before topping up oil is filtered throughly. We use HT grade 11 KV oil even for the LT equipment for better dielectric strength and high flash point.
Protection: We will give tripping to your existing ACB/MCCB in case of single Phasing with single phase preventer. Under voltage cut off and over voltage cut will also be provided.
 
AVR - Linear Copper strip wounded regulators in Diiffrential Winding, plus / minus type with negligible losses due to differential winding as regulator part is out of ckt on minimum amd maximum conditions. This regilator is wounded with copper strip wheare as in market the series type regulator are made of copper wire with highest losses due to series winding. The losses of our regulator are 1/18th in comparision to others. Self lubricating carbon roller assemblies.

CARBON ROLLER: We are giving self lubricating carbon roller assemblies with working life of 1 lakh track meters instead of Carbon brush used by others. Our rollers are point contact with least wear and tear as surface area in contact keeps on changing during the motion and heat is dissipiated through out the body resulting in very high working life on maximum temperature rise with spring tension behind to keep the roller intact with coil for trouble free operation for ages.
