Product Description

 

Product Description

SCB15 Series Amorphous Alloy Transformers
       have the advantages of low no-load loss, no oil, self-extinguishing, moisture resistance, crack resistance, and maintenance-free operation. They can replace ordinary dry-type transformers in any application and are suitable for high-rise buildings, commercial centers, airports, oil platforms, maps, tunnels, airports, stations, industrial and mining enterprises, and power plants. They are particularly suitable for installation in places with high fire protection requirements, such as flammable and explosive environments.

Main Features

1. Small size, light weight;
2. Safe, reliable, non-polluting, can be directly operated at the load center;
3. High mechanical strength, strong short-circuit resistance, low partial discharge, good thermal stability, high reliability, long service life;
4. Low no-load loss, high efficiency, low noise, significant energy-saving effect;
5. Good heat dissipation performance, strong operational capability, and capacity can be increased during forced air cooling;
6. Good moisture resistance, suitable for operation in high humidity and other harsh environments;
7. Environmental protection, flame retardant, explosion-proof, maintenance-free;
8. For products with a capacity of 200KVA and above, the low-voltage winding is made of copper foil, the high-voltage winding is made of 180°C high-strength enameled wire, and the epoxy resin casting structure is adopted, providing excellent moisture resistance and crack resistance. The iron core is made of amorphous alloy tape, with a rectangular cross-section and three-frame three-column structure.

 

Our company's transformer design and development technology is based on extensive physical model experiments. We have independently developed software for calculating transformer magnetic leakage, short-circuit mechanical forces, and load losses. This enables comprehensive optimization of the transformer's electrical performance, providing users with the lowest lifecycle operational costs. Structural design utilizes three-dimensional finite element analysis software to analyze transformer cores, coils, and components, ensuring enhanced mechanical strength, short-circuit resistance, and reduced noise.

 

Features:

Low no-load loss (approximately 70% reduction compared to current SCB10 dry-type transformers). High efficiency, low noise, significant energy savings. Small volume, light weight. Safe, reliable, pollution-free, capable of direct operation at load centers. High mechanical strength, strong short-circuit resistance, low partial discharge, good thermal stability. High reliability, long service life. Good heat dissipation performance, strong operational capability, capacity can be increased when forced air-cooled. Good moisture resistance, suitable for operation in high humidity and other harsh environments. Environmentally friendly, flame-retardant, explosion-proof, maintenance-free. Transformers with capacities of 200kVA and above have foil-wound low-voltage coils, high-voltage coils wound with 180°C high-strength enameled wire, and are cast with epoxy resin for excellent moisture resistance and crack resistance. The core is made of amorphous alloy strip wound into a rectangular cross-section, three-phase three-column structure.

 

 

production process

 

1.Amorphous alloy material has no crystalline structure and is a type of metal processed using special rapid quenching technology. It exhibits low magnetization power, good heat resistance, and soft magnetic properties. Transformers made with this material are a new type of energy-saving transformer, reducing no-load losses by over 70% compared to current S11 distribution transformers.
Wound core process
2.Coil
    amorphous oil-immersed coil

The coils are rectangular, with high-voltage coils wound with alkyd enameled wire. Low-voltage coils are wound with wires or foils to enhance the transformer's ability to withstand short circuits.
