Cast Resin Transformer
LS cast resin transformer takes pride in the ability to offer a wide variety of designs and configurations necessary to satisfy customer needs. Computer and CAD/CAM systems are used for quick and accurate design and manufacturing to meet specific customer requirements.
Features
Short Circuit Strength
- Vacuum-cast with epoxy resin with excellent electrical and mechanical strength
Easy to Maintain
- No oil exchange and firefighting equipment
Overload Tolerance
- Excellent overload tolerance compared to the oil immersed type transformer
Eco-friendly
- No environmental contamination due to oil spills
Suitable for Power Supply to Equipment with Rapid Changing Loads
Humidity Resistance
- Coils are vacuum-molded to prevent entry of moisture
Non-combustibility
- Uses non-combustible epoxy resin to prevent fires
Excellent Impulse Voltage Strength
