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.

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.

SCB13 dry type power transformer product features. Low loss: the no-load loss of the product is 20% lower than that of the SCB11 product, and the energy saving effect is excellent, running economy and maintenance free. Low noise: product noise level is 10 to 15 decibels lower than the current professional standard JB/ t10088-1999 "6-220kv transformer sound level". Low set: resin mixed materials adopt the most advanced mixing method in foreign countries and vacuum film degassing technology, so that the mixture is evenly mixed and the bubbles in the mixture are excluded. The product only has extremely low local discharge, can be controlled under 5PC. The high and low pressure coils are poured under vacuum and pressure, so that the resin insulation can be both encapsulated and inter-turn. The casting body has a dense solidified structure, which is resistant, explosion-proof and pollution-free. The glass fiber and other insulating materials of winding coil have self-extinguishing characteristics, which will not cause the electric arc of short circuit, and the resin will not produce poisonous and harmful gas in high heat. High mechanical strength: packing resin to make casting body expansion coefficient difference is small, small curing shrinkage rate, small internal stress, curing of high hardness, the internal and external surfaces of the high and low voltage coil epoxy resin coating layer, placed with the strengthening of prefabricated molding material, especially as dense as the reinforced concrete structure, and mechanical strength is greater than the pure epoxy resin, can withstand the sudden and short-circuit force without damage.
