Product Description

 H.T. Transformers

These H.T. Transformers operate in a closed loop system for the regulation of power supply output. H.T. Transformers provide better efficiency and are perfect for protection of motors and preventing leakage current and reduce electrical noises.  We manufacture these H.T. Transformers using high-grade raw material and components. Our clients can avail these in various sizes as per their requirements and are ranged at affordable prices. H.T. Transformers is offered in a wide range which is highly appreciated by clients for its features like durability, reliability and high performance, easy to install, maintain and handle. Almost every constituents of the HT transformer is fabricated and accumulated with accuracy and extreme care. The main procedure lines of the transformers is:

Core: The core is completed with laminated and small loss electrical steel sheets that is imported, grain oriented, cold rolled and sheets of superior quality steel. The cores are accumulated in a manner that they decreases the sound caused by trembling; individual stamping are layered with insulation polish which is defiant to heat and oil on both sides. The core is associated to the clamp which guarantees that it is effectually earthed. The core legs are surrounded with heavy duty insulating tape. The yokes are firmly and safely fastened amid the folded steel channels. Clamps on top and bottom are rigidly connected to each other by the means of tie rods. Tie rods offers the dual purpose of reassigning the load from the bottom to the top clamps and securing the winding in place. This avoids tensile stress being associated in the core legs, which could unfavorably influence the iron losses.


WINDING: Transformer windings also called 'Coils' are specifically intended to meet three basic prerequisites: thermal, mechanical and electrical. These windings wound concentrically and are cylinder shaped. Both H.V. & L.V. type windings are wound with sufficient securing and brazing tapes in order to get a strong, forceful and self-supporting arrangement. It is offered with inter layer ducts which make sure low heat grade between windings and oil so the hot spot temperature is kept to low. This ensures that the rate of insulation corrosion is lowered to achieve high life expectancy.

WINDING CONNECTIONS: Tapping and phase leads run in paper covered conductors. Sufficient barriers are used to detach the phase leads from the tapping. Severely brazed tubes are used to preserve the required clearance from coil to tank.

LV Leads, larger in cross-section, are generally strong and tough, where needed supports are provided.

INSULATION AND IMPREGNATION
The major ingredient of insulation is padding pre-compacted pressboard. The element like ring ducts merged spacer; blocks etc. are put under pressing along with the coil assembly for preshrinking. The irrelevant improvement in dimension after the preshrinking is pleased by providing additional insulation. This diminishes the probability if loops getting loose during process and also reduces the breakdown due to short circuit forces.

SHORT CIRCUIT CAPABILITY
In the order to avoid deformation under short-circuit forces; solid insulation end block and ring are used. Winding are squashed under top and bottom clamping members with the assistance of tie rods. The axial end thrust under erroneous conditions is reduced by the suitable balance of the ampere-turns over the span of windings. In case of larger transformer, the HV tapping leads are moved out from two positions to equilibrium the short-circuit forces in a much enhanced way.

TANK CONSTRUCTION

All tanks are fabricated from mild steel sheet of sufficient thickness with ridged wall panel type radiators of hard-pressed steel fin/cooling tube for heat indulgence.
All tanks are verified by magnaflux, ultraviolet ray die piercing system to guarantee that there is completely no seepage from any part of the tank.

QUALITY FINISH THROUGH USE OF SHOT BLASTING TECHNOLOGY
Tanks are shot blasted to eliminate mill and welding scale and then a basic-coverage coat is instantly applied to the external to eradicate oxidation creation.

After priming, all tanks obtain a coat of transitional paint and after pressure testing; they receive a ultimate coat of high gloss paint applied by spray. This guarantees high coverage serving to battle oxidization in unreachable place.
