Product Description

Product Description

Cast Resin Dry-Type Transformer

Pearl Electric's cast resin dry-type transformers feature low noise, low loss and low partial discharge. It employs a rational structure,high-quality materials, scientific design, strict craftsmanship and advanced testing methods.

Capacity: Up to 40MVA
  Voltage: Up to 69kV

Pearl Electric's Cast Resin Dry-Type Transformer Features

· Superior short-circuit resistance and high lightning impulse withstand capability.

· Excellent damp-proof performance. Operatessafely in up to 100% relative humidity for short periods without pre-dehumidification, making it ideal for coastal, humid and other harsh environments.

· Outstanding overload capacity: 110% rated load for continuous operation, 150% rated load with forced air cooling (AF).

· Flame-retardant and non-explosive design. Oil-free structure eliminates the risk of oil leakage and environmental contamination, no toxic gases released during operation.

· Premium H-class epoxy resin casting structure delivers excellent crack resistance and superior thermal dissipation, ensuring long-term reliability.

· Compact and lightweight design significantly reduces installation space requirements and overall civil engineering costs.

Core:

LV Winding:

HV Winding:

Our transformer utilizes a high-quality cold-rolled grain-oriented silicon steel core with high magnetic permeability and 45° slope lamination, significantly reducing no-load loss and current.
 
Through simulating analysis in core model design, we precisely calculate vibration frequency and size, preventing core cavity resonance. Spring connections between the core and windings, and the core and frame, reduce noise by 10-15dB below the standard.

For enhanced anti-short circuit capabilities, LV windings exceeding 400 kVA now utilize advanced foil conductors. This design improves ampere-turn balance and minimizes transverse magnetic flux leakage.
 
Additionally, an optimized air passage within the winding significantly enhances heat dissipation, lowering temperature rise and increasing the product's overload capacity.

HV windings utilize high-quality copper conductors with fiberglass-reinforced insulation. They are vacuum-cast using a German HUBERS machine to ensure optimal resin penetration, significantly reducing partial discharge (e.g., below 5pC for 11kV products).
 
Optimized structural design enhances the electric field distribution, and advanced lightning wave simulation technology substantially improves the transformer's anti-lightning capability.
