Insulation Resistance
The two figures show typical curves for the insulation resistance.
Insulation resistance of ISOMIL measured with 20V DC.
Insulation resistance of ISOMIL measured with 500V & AC / 50Hz.
For both mineral insulated thermocouples and mineral insulated heating cables the
standards (e.g. DIN 43721, ASTM E 420/71,
VDE 0284) lay down dc measurements.
Since polarization currents are accompanied
by a time dependent increase of the insulation
resistance after applying dc voltage, the
measurement value is read off after 60 & 3s.
The displacement currents lead to considerably
lower insulation resistances especially in
the temperature range below 600&C. When
considering an FI switch as a protective
measure, the above must be given careful
consideration when designing the circuitry
in equipment with mineral insulated heating
Dielectric Strength - Bending Radius
Mineral insulated cables can easily be wound into a spiral. The minimum bending radius
varies according to the width of the sheath and is three to five fold the outer diameter.
Bending causes a reduction in density in the insulation material under the outer edge of the
sheath, this reduction increases the smaller the bending radius. The associated reduction in
dielectric strength conductor/sheath is of significance especially for ISOMIL-H.
Dielectric strength as a
function of bending radiusmeasured
on ISOMIL-H at
alternating voltage (50 Hz).
Measurements have shown that the dielectric strength is virtually temperature independent
up to 800&C.::::::工德股份有限公司::::::

NI-G-S was developed originally for heated
high temperature press platen steel mold. NI-G-S has been installed at the mold
lateral sides to minimize the heat loss, enabling a much better mold
temperature control and reduce heat transmission to the environment.
It can also be used many other areaswith elevated temperature where a light
