NBRAM reviews customer drawings for custom shape mica insulators every week. Thickness, tolerance and cut method decide fit: 0.1-50mm stock, 0.1mm accuracy, waterjet edges, 1000°C service.
A look at mica thermal insulation boards inside heater builds at 900°C: dielectric strength, 0.71 W/mK conductivity, 1-10 mm thickness selection, edge treatments and batch thermal cycling.
Busbar joints run hot while carrying voltage, so the spacer has to do two jobs. NBRAM Mica-Ceramic Composite Parts work from -60°C to 950°C, hold 15-25 kV/mm and resist electrical tracking.
KSD 9700 Series bimetal thermostats from NBRAM: 0°C to 250°C, ±2°C accuracy, 16A/250V AC, automatic reset. Multi-point calibration, helium-tested seals and thermal aging on every unit.
Silicone bonded flexible mica plate from NBRAM: resin aged to a target viscosity, vacuum impregnated and slow cured, so 0.15-3.0mm sheets hold ±0.01mm and 18-22kV/mm after 600°C exposure.
How NBRAM builds iron mica insulation gaskets: 0.5-6.0mm iron-on-muscovite laminates, +/-0.02mm thickness, 18-25 kV/mm at 600C, 25-35 MPa layer adhesion and sealed edges for flanges.
