PAPER COVERED COPPER WIRE
Paper covered copper wire is a special electromagnetic wire with an insulating paper layer tightly wound on the surface of a high-purity copper conductor. It combines traditional paper insulation technology with modern copper material technology. This structure not only retains the excellent conductivity of copper, but also achieves reliable electrical isolation through the paper insulation layer.
The wire exhibits excellent heat resistance and electrical strength. The unique microporous structure of the paper insulation layer facilitates impregnation treatment and can form a composite insulation system. The copper core provides stable conductivity, while the multi-layer paper package structure gives it good mechanical protection and heat dissipation characteristics, which is particularly suitable for long-term work in harsh environments.
It is mainly used in the winding manufacturing of oil-immersed electrical equipment such as large power transformers and reactors, and performs well in situations where high voltage and high temperature are required. Its reliable insulation performance and traditional process advantages enable it to continue to play an important role in key areas such as the power industry and rail transportation.

EXCELLENT CONDUCTIVITY
The use of high-purity copper conductors ensures current transmission efficiency, and the conductivity is stable and reliable, meeting high-standard power transmission requirements, and is suitable for precision electrical equipment.
EXCELLENT HEAT RESISTANCE
The paper insulation layer is combined with a special impregnation process to form a high-temperature resistant insulation system, which is suitable for long-term high-temperature operation of equipment such as transformers, ensuring safety and stability.
RELIABLE INSULATION PROTECTION
The multi-layer paper package structure provides uniform insulation layer thickness, effectively preventing high-voltage breakdown, and ensuring the safe operation of electrical equipment in harsh environments.
GOOD IMPREGNATION PERFORMANCE
The porous paper layer structure facilitates full absorption of insulating paint or transformer oil, forming a more complete composite insulation system and improving the overall insulation strength.
ENVIRONMENTAL PROTECTION
The use of natural fiber insulation materials has little pollution in the production process and can be naturally degraded after disposal, which meets modern environmental protection concepts and sustainable development requirements.
