- Details
Electrical Semiconductor creped insulation paper is a new kind of special shielding material.Mainly used for high voltage transformer,new energy transformer lead wrapping,interlayer insulation foil winding,ultra high voltage power cable,high voltage electrical equipment lead and coil insulation wrapping.It can replace metallized paper and other surface type semiconductor materials.It has excellent wettability,lowconductivity,shielding static electricity,also can solving partial discharge and balancing high voltage electric field.
Recommended width:
700mm、1100mm;it can also slit it to be belts.Tailor-made by customers' requirements is available.
Storage
The product should be stored in dry,clean and well-ventilated warehouse.The fire,heat sources and direct sunshine should be avoided.The storage period is one year,qualified products exceeding the storage period can still be used.
