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.

Resin cast current transformers are available for metering and protection application. These current transformers are mainly fabricated according to client’s specification. Ct coils are encapsulated in cast resin (polyester / epoxy). Secondary terminals are provided with either screws or studs. The main insulation between primary and secondary and earth is obtained by this epoxy resin. These transformers are of compact design with high mechanical and electrical properties. These are non-hygroscopic and hence give very good insulation properties even in given humid conditions. General particulars Rated voltage: 11 kv Rated primary current: 100 a Rated secondary current: 1a or 5a Rate burden: 5va Rated frequency: 50hz Accuracy class: 0.5 or 0.5s Temperature: as per is-2705/1992 Highest system voltage: 12kv Insulation level: 28kvrms/75kv(p) Stc: 13.1ka for 1 sec Continues thermal current: 1.2 times of rated current Core material: crgo Copper wire material: enameled wire as per is-4800 part-4 or iec-317 Insulation class/material: epoxy resin Secondary terminal: m5 brass bolt with nut &washer or m5 threaded bush with screw &washer Primary terminal p1 & p2 size and material Mounting base: ms 5mm thick zinc plated Rountine test :as per is-2705/1992
We manufacture highly efficient and accurate resin cast potential transformers. These resin cast potential transformers are used in ac circuits, for the purpose of measuring large voltages. Their main function is to reduce the supply voltage to a small value so that it can be easily measured with standard low range ac instruments of moderate size and capacity. There are many advantages of using resin cast potential transformers for range extension of ac meters. We also offer resin cast potential transformers of dual purpose metering & protection that are also commonly used.

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
