Alfo manufacturing aluminium foil wound transformers in india.
We alfo electric, manufacturers of power conditioning equipment and instrumentation and control equipment for energy management. This position of market leadership has been enabled by providing greater value to the customer through accent on value engineering resulting in better quality and reliability at a lower cost.
One of the major impact areas of value engineering is in the use of aluminium foil wound transformers, as our power conditioning range of products had a high copper content, the possibility of reducing our dependence on copper due to its relative high cost and price instability was considered. This resulted in our using aluminium foil wound transformers in place of copper wire wound ones.The aluminium foil wound transformers so developed have been successfully used in stabilisers and isolation transformers are working on the field since 2007. As this manufacture involves a convenient and efficient method of winding the foil around the core, we designed and developed the special purpose cnc foil-winding machine. We introduced this unique construction technology, providing practical and economical aluminum foil-wound transformers in the 1 kva to 500 kva power range.

SC(B)10 Series Resin-insulated Dry Type Transformer,cast resin transformer,dry-type transformerï¼?cast resin dry transformerï¼?step up dry transformer Dry Type Transformer Flame retardant, non-pollution, it can be installed directly in the load center. Maintenance-free, easy to be installed, low operating costs. Product Features Function Characteristics: Flame retardant, non-pollution, it can be installed directly in the load center. Maintenance-free, easy to be installed, low operating costs. The enclosure can be of Good moisture resistance, transformer can be put into operation without pre-drying under 100% humidity in the normal operation. Low loss, light weight and small volume, low noise, good dissipation of heat, it can be 150% rated load operation under forced air cooling conditions. Equipped with a complete temperature protection control system to provide reliable protection for the safe operation of transformers. High reliability. The results of checking for the products that has been put into operation show that the reliability index has reached the international advanced level. Structural Characteristics: Foil Coil: Adopting the entire section of copper foil, together with the F-class turn insulation, low voltage winding is wound by the special low-voltage foil winding machine. The foil coil resolves problems such as large short-circuit stress, ampere turn unbalance, poor heat dissipation, existing the winding spiral angle and unsteady manual welding quality due to low voltage and large current coil. At the same time, the end of winding is treated with cast resin, solidification to make shape, moisture-proof and anti-fouling, the lead for copper bar is welded by argon arc welding automatically. Temperature Control Device: the transformer adopts BWDK series of signal thermometer. The temperature components are embedded in the upper half of the low-voltage coil, can detect and display the temperature of separate phase coil automatically and continuously, also have the functions of over-temperature alarm and trip. We are pleased to deliver Transformer, Distribution Transformer, Power Transformer, Oil Transformer, Dry Type Transformer. Safe payment and on time deliver time will give you.If you want to know more about the product, please click here.
Multi-layer winding coil Low-voltage coil adopted high quality foil and rolled with the automatic foil machine, argon arc welding with high-accuracy standard; presoak dmd in the interlamination as insulation material. Use presoak glass for insulation both outside and inside, sealed with epoxy resin, followed by solidify in the curing oven, in order to reached the target of high level of humidity resistance. About amorphous metal transformer Amorphous metal transformer introduction The development of the amorphous metal in 1970s, it has been widely used in 1990 for a high energy saving material for the transformer industry. Right now, over one million sets of amorphous metal type transformer had been connected to grid all over the world. The longest proven save and reliable transformer had been running for more than 30 years, and it still perform satisfactory in the power industry. The energy saving is huge and it shall be the new era products in the power industry
Cast resin transformer For the demand of safety for the power distribution equipment, dry type transformers with fire resistant, non-polluting and humidity resistant features are often the right choice. Hsl cast resin transformer will provide the best and safest solution to all kinds of power distribution system application. Features: Hazard-free to the environment Designed for reliability, safety and flexibility, hslí»s medium voltage cast resin transformers are tropicalized, maintenance-free, environmental-friendly, flame-resistant, self-extinguishing, moisture-proof and space optimization and suitable for application to a wide range of industries such as high rise buildings, power plant, airport, hospitals, museum, hotels, all sectors of industry, surface, underground and tunnel railway systems, oilfield, electric grid, mining, etc. Our standard range of cast resin transformers is 30kva up to 2500 kva, however, we are able to design and manufacture special units to suit most applications. The magnetic cores are made of low specific loss high magnetic silicon steel isolated on both sides by a thin inorganic coating (carlyte). The cores are cut at 45 degrees while uniform pressing, stiffness and solidity of the columns assure a low noise emission. The hv windings, coaxial to the column of the core, are obtained using electrolytic aluminum or copper strips insulated in f class, impregnated to a vacuum system with oven-dried in class f, a high level of cementation which provides the coils a very good isolation and mechanical seal. The lv windings are generally made from electrolytic aluminum or copper foils having class f inter-turn pre-impregnated film insulated and then oven dried. Hsl is an iso9001:2000 compliance manufacturer. Our transformers will be 3-phase, 50hz in frequency, naturally cooled and are manufactured equivalent of iec726 standards.
