In which industries is Thermally Upgraded Kraft Paper mainly used

      Thermally Upgraded Kraft Paper is a special insulation kraft paper that has been thermally stabilized and modified, with a core positioning of electrical insulation

1、 Power Transformer Industry (Largest Application Area)

Oil immersed distribution transformers, power main transformers, dry-type transformers, coil interlayer insulation, turn to turn isolation, and phase to phase barriers;

Core wrapping insulation, lead insulation liner, insulation cylinder substrate;

Internal layered insulation of high-voltage transformers and reactors;

Advantages: Long term stability at 120 ℃ without embrittlement, low dielectric loss, resistance to long-term thermal aging, and extended service life of transformers.

2、 Electric motors and new energy drive motors

Insulation of stator coils, slot insulation, and winding lining paper for industrial high-voltage motors, fan and water pump motors;

New energy vehicle drive motor, energy storage inverter motor, wind turbine generator coil wrapping;

High speed automatic winding machine specialized for folding and upgrading kraft paper tape, with high-speed wrapping that is not easily broken and suitable for automated production lines.

3、 Manufacturing of electromagnetic wires/enameled wires

Used for wrapping insulation paper tape on the outer layer of enameled wire, high-speed winding process, providing intermediate insulation layer, improving the temperature and voltage resistance performance of the wire, and adapting to the processing of motor and transformer winding wire.

4、 High voltage electrical and capacitor industry

Isolation medium for the cores of power film capacitors and high-voltage parallel capacitors;

Insulated paper lining switchgear, transformers, and insulation components to block high-voltage creepage;

Small high-voltage power supply, special pulse equipment interlayer insulation.

5、 Photovoltaic energy storage electrical matching

Internal inductance of photovoltaic inverters and energy storage converters, insulation pads of transformers;

Energy storage PACK is equipped with small drive coils and interlayer insulation for power inductors;

Suitable for long-term enclosed high-temperature cabin conditions, with better thermal stability than ordinary insulation paper.
