Mechanical calculation

Bushes are applied for terminal of wires of high potential from tanks of transformers, oil switches, and also for a lining of wires through walls of buildings. Hey are installed the bush on a cover of the tank or on a wall of the building the metal flange. Bushes can well work at height of no more then 1000м above sea and in an interval of temperatures from-40 up to +45° with relative humidity up to 85%. Corresponding designs of isolators can be used for other, heavier environmental conditions.
