Micaver® Standard Insulators

Electrical insulation is the major Micaver application which covers a wide range of standard products. Insulators must be able to meet a large number of specifications required by users. These specifications may combine several technical characteristics such as, mechanical (compression, flexion...), thermal (expansion coefficient) or electrical (dielectric rigidity, arcover voltage, perforation voltage ...). Insulators made of Micaver make use of the unusual properties of the material, in particular its very low Thermal Coefficient of Expansion that generates exceptional dimensional stability of parts made from it and allow metal inserts to be incorporated during the moulding process. Saint-Gobain Quartz also proposes modified standard insulators, results of modifications on the diameter, length or type of the inserts - all modifications that do not affect the shape and the dimensions of the insulator. Eventually, we would be glad to make your needs becoming one of our new standard (Please contact our Sales Department for any demand on such products).

Standard insulators

  • Categories
  • Properties

Standard insulators are divided into categories :

 

  • Insulators :

       - Biconical and symetric with inserts that comprise, on the outside, tapped holes and/or threaded rods

       - Skirt-type and/with anchored inserts and tapped holes only

 

  • Studs, designed as mountings for brushholders, of which the insert consists of two smooth rods.

 

  • Bushing, reinforced with a single threaded rod that crosses through the whole body

Micaver insulators hold a special range among other insulators thanks to the remarkable properties of Micaver, positioned in-between  thermoplastics and ceramics properties.

 

  • Hardness and compactness
  • Great mechanical strength under tension and compression 
  • Great resistance to impact
  • Excellent dimensional stability in temperature
  • M0 classification : it does not burn
  • Excellent weatherability
  • High resistivity (surface and volume)
  • Suitable to use in vacuum chambers (no outgasing)
  • Good resistance to chemicals
  • Relatively insensitive to radiation
