Oil duct for transformer
Description
Paper Board Oil duct/grid is made by bonding transformer board sticks onto insulating paper or single-coated diamond dotted paper.
Features
This paper is highly refined and cleaned to ensure uniform thickness and free from formation Pinholes, un-dispersed fiber bundles and tiny defects
It is a low-voltage grade insulating paper well suited for making electromagnetic wires, power cables of
transformers below 35kV and other electrical insulating equipments below 35kV
This paper has stable electrical and chemical properties, and high physical strength to meet the exacting
needs of our valued customers
Applications
Used widely as electrical insulation wrap on aluminium and copper wires by conductor manufacturers,
electrical insulation between layers of wound coils in electrical motors, in capacitors, transformers & such
other electrical equipment.
Specifications
Our ordinary insulating papers are available in nominal thicknesses from 50 to 250 microns,
and in continuous rolls up to the widths of 625, 960mm and 1200mm (the roll diameter being 680 to 730mm),
or other customized diameters and widths on request.
