A rare item for a collection

Made in USSR in 1965

Two hemispherical cups made of iron-molybdenum alloy, coated with activated barium oxide.

Arresters of the RB-280 type are connected between the wire and the ground and are triggered when the induced voltage relative to the ground exceeds their discharge voltage.

Designation: R - arrester; B - barium; 280 V - average discharge voltage. Deviation is allowed ± 30 V.

The spark gap consists of a flask in which 2 electrodes are placed, which include barium. The flasks are filled with argon.

Breakdown voltage, V:
