Adopted high-purity sulfate wood-pulp electrical pressboard, excellent insulation performance, suitable for long-term operation in oil-immersed transformers.
High mechanical strength and short-circuit-resistance, firmly support winding coils to avoid deformation and bulging.
Precision-machined dimensions with tight tolerance, guarantee high assembly accuracy for windings.
Multiple profiles available: rectangular, T-shaped, dovetail type, compatible with insulating spacer blocks for assembly.
Smooth burr-free surface without sharp corners, effectively prevent partial discharge risk.
Form uniform axial oil ducts, optimize transformer oil circulation and dissipate coil heat rapidly.
Low water-absorption shrinkage, stable dimension after oil immersion, resistant to deformation in long-term service.
Custom cutting available per customer drawings & samples, fit various transformer parameters flexibly.
Physical-chemical properties comply with transformer industry standards, good compatibility with transformer oil.
Clean impurity-free material, no dust shedding, maintain clean internal operating environment for transformers.
