ISPP - 1A bushing insulators are available in a pressed glass case. They are used for hermetically sealed the lead - out parts of radio equipment and electrical equipment. Function in the power lines of regular and variable signals. Insulators are manufactured according to SKNTs 552327.191TU of the same type ISPP - 1A, the letter I means the insulator, C - glass case, P - pressed case, P - bushing, 1a - type of insulator design.
Mounted in hardware using soldering. The basic dimensions of insulators and their structural elements must meet standard parameters. The standard designation of insulators in orders and engineering documentation is made up of the wordelter ”, short designation ISPP - 1A, rated voltage, outer diameter of the washer D, outer diameter of the tube d and designation of real TU.
For insulators having thermostability parameter 200 of C at the end of the notation attached hyphenated letter "T". For insulators with a washer height of 2.5 + 0.1 - 0.2 and a tube height of 6.0 + 0.4 - 0.2 through the hyphen, the letter "B" is attached.
Automatic factors that influence the operation of insulators include a sinusoidal vibration index with a frequency range of 10 - 2,000 Pr, acceleration of 5,000 m / s 2 (500 g), an automatic one - time impact with an acceleration of 10,000 m / s 2 (1,000 g ) and automatic reusable impact with an acceleration of 1,500 m / s 2 (150 g).
By climatic factors influence the operation of the insulators include increasing the working temperature of the medium to operation 125 of C and up to 200 of the C, lowering the operating temperature to - 65 operational environment of C, atmospheric pressure with a reduced value of 133 x 10 - 6 Pa (1 * 10 - 6 mm Hg).
