Electrical Insulation Material

We are a leading Supplier & Manufacturer of Electrical Insulation Material such as Flexocoat Base & Hardener, Round Mica, Syndanio Sheets, FRP Washers, Yoke Mica, Asbestos Rope and many more items from India.


Asbestos Millboard Sheets

This is a versatile, thermal insulation and heat-resistant material produced in sheet form using good quality asbestos fibers, incombustible fillers and vegetable binders. It does not suffer loss of strength upto 485°C. When
suitably supported the board can be used satisfactorily at extreme temperatures upto approx. 1400°C.


Service

For all kinds of thermal insulations ranging from domestic cookers and ironing boards to industrial
applications such as glass moulding, ovens and furnaces and domestic stoves. As the sheets can be bent to any diameter with a little moisture, they are most suitable for large diameter pipe cladding.

Flexocoat Base and Hardener

Flexocoat Base and Hardener
Flexocoat Base and Hardener

It is a epoxy paint having excellent adhesion, very good electrical & Mechanical properties include thermak shock resistance coupled with long durability. Available in 1 kg pack ex stock. Applications: This coating is mainly used to insulate the coil of Induction Furnace, It has excellent adhesion on copper and stainless steel with desire flexibility to withstand cooling and heating cycles normally encountered during operation of furnaces and provides electrical resistance to voltage developed between coil turns to protect from sparking.

Round Mica

Round Mica or Ring Mica is made from Hard Mica sheet cut as per required radius and width, Normally one ring is made from several segments. It has very good Dielectric strength.

Application

  • It is used for provide insulation between turns of Induction Furnace Coil.
  • Available in different thickness from 3 mm to 12 mm

Syndanio Sheets

This is a non arcing, compressed asbestos sheet. Available in a standard size of 42” x 48”. Thickness available from 3. 5mm to 75mm the sheet is machinable so by machining we can produce syndanio spacers, syndanio washers, syndanio bushes syndanio rings, syndanio top-bottom of crucibles, this is used as electrical insulation purpose in industry.

Nomex Paper

Nomex paper is an insulation paper which offers  high inherent dielectric strength, mechanical toughness, flexibility and resilience. Nomex is the original form of Nomex paper, and is widely used in a majority of electrical equipment applications. Available in 11 thicknesses (0.05 to 0.76 mm) (2 to 30 mil), Nomex paper
Type 410 is used in almost every known electrical sheet insulation application.


Electrical properties

The typical electrical property values for Nomex paper are shown in Table I. The AC Rapid Rise dielectric strength data of Table I, representing voltage stress levels, withstood 10 to 20 seconds at a frequency of 60 Hz. These values differ from long-term strength potential. DuPont recommends that continuous stresses in transformers
not exceed 1.6 kV/mm (40 V/mil) to help minimize the  risk of partial discharges (corona). The full wave impulse dielectric strength data based on multiple sheets. These values are appropriate for the applications which employ these materials in such configurations. Data based on single sheets of material are available upon  request.
The geometry of the system has  an effect on the  actual  impulse strength values  of the  material.  The dielectric strength
data are typical values and not recommended for design purposes. Design values can be supplied upon request.
