Product Description

Product Description

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.

Product features: good flame retardancy, insulation and high electrical strength; low water absorption and moisture resistance, good dielectric resistance, good mechanical strength and processability.

Product use: used for insulating structural parts and padding insulation boards in various electronic and electrical equipment, various motor slot wedges, gaskets, outlet boards, various transformer support strips and pads; can be used in humid environments and transformer oil; can be processed into various large motors, electrical and electrical insulation structural parts.

Product material: made of transformer cardboard as raw material, bonded and pressed with insulating glue,

Production process: The application of new processes and equipment avoids problems such as bubbles, delamination, embrittlement, etc. that may occur in laminates. The veneer made by steaming, peeling and drying is coated with special insulating glue and made by high temperature and high pressure.
