What is the purpose of Electrical Insulation Aramid Board

      Electrical Insulation Aramid Board is a hard board formed by hot pressing aramid fibers (mainly meta aramid). It has a long-term temperature resistance of 210-220 ℃ (H/S level heat resistance), high voltage resistance, self extinguishing flame retardant, vibration resistance, and high temperature non melting. It also has dual functions of electrical insulation and structural support. It is mainly used in high temperature and high pressure conditions that ordinary epoxy boards and phenolic boards cannot handle.

1、 Summary of core functions

      Realize electrical isolation between live parts and between live bodies and shells; Simultaneously serving as insulation support partitions, pads, and barriers, withstanding mechanical pressure and continuous vibration, maintaining insulation stability in high temperature environments, suppressing partial discharge, and preventing arc propagation.

2、 Segmented application scenarios

1. Transformer industry (dry-type transformers, rail transit traction transformers, medium frequency transformers)

      Winding interlayer insulation partition, phase to phase insulation baffle, end insulation support, lead insulation lining plate

      High and low voltage coil isolation barriers, iron core and winding insulation pads, terminal insulation pads

      Advantages: Resistant to overload temperature rise, less prone to cracking in vibration environments, and reduced risk of partial discharge

2. Various types of high and low voltage motors and generators (wind power, mining explosion-proof motors, high-speed rail traction motors)

      Stator end insulation support plate, phase to phase insulation partition, wiring terminal insulation pad

      Reinforcing insulation with slot wedges and insulation blocks at the outgoing line locations; Low dielectric loss in high-frequency operating conditions of frequency conversion

3. In the field of new energy (photovoltaics, energy storage, new energy vehicles)

      Energy storage inverter PCS, photovoltaic inverter power module insulation isolation pad

      Drive motor insulation support, internal insulation partition of high-voltage distribution box, busbar insulation liner

      Insulation and heat insulation baffle for power battery module (combining insulation and flame retardant insulation)

4. High and low voltage electrical control and switching equipment

      Bus phase insulation partitions, internal insulation supports for circuit breakers/contactors

      High voltage terminal insulation pad, internal insulation isolation barrier of cabinet

      Special testing equipment, intermediate frequency power supply, and insulation structural components of induction heating equipment

5. Special electrical equipment for aviation, shipbuilding, and military industries

      High temperature resistant insulation structural components for ship motors and onboard power equipment, suitable for humid, hot, vibration, and wide temperature environments.

3、 Easy distinction from aramid paper (commonly used in business)

      Aramid insulation paper: flexible roll material, suitable for wrapping, groove lining, and coil wrapping;

      Electrical insulation aramid board: a hard board that can be cut, drilled, and milled, used for insulation components that require load-bearing and structural support.
