Dry Type Transformers Dealers

A dry type transformer has an iron core, vacuum pressure resin impregnated high voltage windings and low voltage windings . The low voltage winding is constructed with conductors. Dupond nomex insulating material includes an apparatus to secure the windings in place during a vacuum and pressure resin impregnation process. The result is a coil that exhibits high short circuit protection due to the tightly bond conductors comparable to completely resin encased molded transformers at a substantially reduced cost. Application in following industries : Chemical, Pharmaceuticals, Steel, Textile, Engineering, Plastic, Cement, Refineries, Mining, Captive Power Projects, Hydro Power Projects, Wind Mill Farms, Construction Houses, Pharma, Electrical, Electronics, Renewable Energy, Automobile.

Dry type Transformers, class 'H' insulated, have insulating materials which are with high dielectric strength and are capable to withstand high temperatures. The temperatures are generally made to comply with IEC-60076/IS-2026/IS-1171. Range upto 1600 KVA and 11 KV Class.   Available versions :   Open type execution for installation in an existing panel or enclosure. Well ventilated enclosure with lip-cut louvers & baffles for outdoor installation. Non ventilated enclosure for outdoor installation. Advantages :   Use of non-biodegradable materials makes these suitable for strict environmental   conditions. No fire or explosion hazards because of use of nonflammable materials & absence of any liquid insulation. Non-requirement of oil sump makes these ideally suitable for installation near   load centers thus reducing cabling costs and improving voltage regulation.

We are offering dry type transformers. These are basically distribution transformers. Dry type transformers are preferred to oil cooled transformer, in place where there is fire hazards e.g. Thickly dense area like big-store, multistory building, theatres etc.

With proven design and performing well in western countries, dry type Transformers are now widely used in Indian market as well. vardhman make vacuum pressure impregnated dry type Transformers are engineered with precision to perform well and efficiently. Salient Feature : Maintenance Free. No Fire hazard therefore suitable to use in indoor applications. Self-extinguishing and hence very safe. High resistance to temperature fluctuations. High impulse and short circuit strength. Environmental friendly. Low partial Discharge. Cable drop can be reduced as can be placed near to load center. Capable of withstanding vibration condition hence high performance in earth quack prone areas.

Capitalizing on our profound industry knowledge, we are engrossed in offering a comprehensive array of Scott & Vee Connected Transformer. Fabricated in adherence with all protection and quality guidelines, the transformer we offer is used at various industrial and other related sectors. Appreciated for its high efficiency, the offered transformer is designed by employing premium grade raw material which we obtain from certified vendors of the market. At last the offered transformer is obtainable at market leading rates.

We offer Dry type transformer are non-explosive fire resistant, air insulated, and are cooled by natural circulation of air through ducts provide in the windings. High temperature and high dielectric insulating materials like glass fiber reinforced, nomex insulating tapes are used in such a way that the entire assembly is capable of withstanding high electrical and mechanical stresses with good dissipation of heat causing low temperature rise within the prescribed limit of insulation class. Standard The Dry Type transformer are manufactured to comply with National International Standards BIS, IS 11171, IEC 76. Description The winding are made up of electrolytic Grade, Soft and bright annealed copper conductors covered with nomex insulating tapes. The wound coils are preheating and impregnated with silicon varnish under vacuum pressure and undergo a curing cycle. The low voltage coils are wound over glass fiber reinforced cylinder having high mechanical strength. The high voltage coils are supported over yoke on glazed porcelain or resin insulators. The core is made of CRGO silicon steel laminations duly annealed after shearing and assembled in mitred construction for low â��NO LOADâ�� LOSS. The yoke frame has adjustable pressure plates to clamp & secure the coils adequately. Lifting arrangements is provide on the top yoke frame so that the core and coil assembly is lifted. OFF-CIRCUIT TAMPING if required are provided on HV winding and terminated on fiber glass terminal board for changing the transformer ratio in â��OFF CKTâ�� position. Applications Fire safety and environmental aspects are of increasing importance especially in respect of energy supply. The substitution of oil-filled transformers by dry type transformers is one of the most important step towards it. Dry Type transformer is used when it has to be located near load center and in a fire hazardous place. As there is no oil used in the transformer and special type of fire resistant insulation are used for the windings the fire risk is considerably reduced. TOP Standard Specifications Capacity Up to 2500 KVA No. Of Phases 3 Phase Frequency 50 Hz. Voltage Range 11 KV Tapping On Load Tap Changer to provide +5% to -15% Taps in steps of 1.25% on the H.T.
