<p>To provide a high-voltage resistor element which is superior to heat resistance, dielectric breakdown strength, vibration resistance and durability performance, and is advantageous to maintenance, inspection, adjustment, replacement and repair, the formation is made up of: a cylindrical outer tube made of metal; a resistive heat-generating wire in a coiled shape tensionally extending between inner ends of electrode rods inserted respectively from both ends of the outer tube; an insulating material filling up a space between the resistive heat-generating wire with the electrode rods and the internal surface of the outer tube and fired; and insulating sleeves extractably encasing and anchored in the portions adjacent to the both ends of the outer tube penetratingly bridging between arrangement boards.</p> |
