Electrical Insulation Paper Sheet
- By : Insulation Materials
Electrical paper sheet made of high-purity 100% kraft pulp then finished by high-pressure processing.
High purity, high mechanical strength, with both mechanical and electrical properties after oil immersion. It is widely used in oil-immersed transformers and reactors, capacitors, switches, etc.
T4 cardboard is more density than the electric board, with larger tightness, smaller shrinkage and good flatness. It is mainly used in equipment such as transformers, capacitors, transformers, etc.(Pie winding parts,like grease block, partitions, cardboard tube, corrugated paper, iron yoke insulation, clip insulation and end insulation winding platen, etc.).
Specifications: Thickness: 5/1/2/3/4/5mm
Long * wide: 1000*2000
Single carrier about: 500Kg
