Description

Insulating Paper for motor is a thin layer of insulating material made of natural cellulose (wood pulp) or synthetic fiber through a special process. It is used for insulation protection of power cables, transformers, motors and other equipment.

Core function: Isolate conductive parts to prevent current leakage or short circuit, and be resistant to high temperature and aging.

Trusted support: Adopt international standards (IEC 60554, ASTM D202)

Product advantages

1/High insulation performance
Typical data: Breakdown voltage strength ≥30 kV/mm
Test basis: Provide a screenshot or number of the test results of a third-party test report (such as SGS, TÜV).
2/High temperature resistance
Data support: Long-term temperature resistance level is 105°C (ordinary type), 130°C (high temperature type)
