High Voltage Insulators

•

Abbatron High Voltage Insulators are ideal for high-voltage,

high-temperature standoff and/or feed-thru applications. They

are not intended for high-vacuum or hermetically sealed use,

nor with heavy shear loads.

•

Temperature ratings recommend Steatite safe operation to

1800oF (980oC). Cushion washers may further limit operating

temperature.

•

Voltage ratings (recommended in table) are specified under

clean, dry conditions only. Moisture and/or dirt will de-rate

up to 50%.

•

Nominal operating current, limited by hardware size, shown

for AC, 60Hz, 10oC rise.

•

These insulators are made from Grade L-5 Steatite per

MIL-I-10E. Hardware is nickel plated brass except for solder

lugs, which are tin plated. Cushion washers are “Champak”,

compressed paper or cork.

Steatite Material Specifications:

•

Water absorption 0.05% maximum

•

2600oC softening temperature

• Coefficient of Expansion 7.5 (In/In. per oC x 10-6)

•

Dialectric strength 250 Volts per mil.

•

.003 power factor at 1MHz

• Clear glaze finish over creamy white colored Steatite material.
