Description
For some time now, electric insulation materials have been at the forefront of remarkable progress in the electronic device industry. Electric insulating cloth has been the material of choice for many years. Varnish cloth is electro-insulating material formed by impregnating nylon fabric with electro-insulating varnish. Synthetic alkyd varnished cloth allows for good flexibility and has good thermal conductivity and great tensile strength. Varnished cloth can easily be cut, processed and shaped to the required specifications. Varnish fabric is suitable for use in conditions of prolonged heating. The product is actively used in various branches of electrical engineering.
Main advantages of the alkyd varnished cloth:
- Multifunctionality of application
- Excellent dielectric properties
- Possibility of operation under conditions of constant exposure to oils and fuel
- Resistance to high temperatures
- Insensitivity to moisture
- Long service life
Areas of application
- instrument and mechanical engineering
- the automotive industry
- electrical engineering
- electric motors
- transformers
- relays
- bobbin
- choke
- throttles
- others
