Electric insulation frame tubes of the TESC brand
TESC pipes (TU 27.90.12-002-91008728-2018)
Electric insulation frame tubes of the TESK brand represent shnurchulki from stekloniti of dense weaving impregnated with an organosilicon sublayer.
Electric insulation frame tubes of the TESK brand are intended for use as a basis for applying a rubber layer in the production of reinforced electrical insulation tubes, as well as as independent products for insulation of output and installation wires of electrical equipment, current-carrying elements of various electrical devices and radio equipment operating at voltages up to 230 V DC and alternating current with a frequency of up to 500 Hz in the temperature range from minus 60 seconds to plus 250 seconds.
TESK brand tubes are available in 2 types:
Type I - tubes with silicone impregnation of the stocking cord;
type II - tubes with impregnation of the stocking cord with organosilicon varnish.
Type I tubes can be manufactured in a variety of colors, while Type II tubes can only be made in natural colors that correspond to the technological color obtained during the production process.
In the name of pipes, the letters mean:
T - phone number;
E - electrical insulation;
With - string-stocking made of stekloniti;
To - frame version.
Example of a symbol for a TESK type I tube with an internal diameter of 5 mm in white:
"TESK 5,0-220B-I tube WHITE. TU 27.90.12-002-91008728-2018"
Example of a symbol for a TESK type II tube with an internal diameter of 5 mm in natural color:
"TESK 5.0-660B-II tube NAT. TU 27.90.12-002-91008728-2018"
The warranty period of storage is 24 months from the date of manufacture.
The service life of tubes as part of equipment (products) is not less than 25 years, provided that the manufacturer of the equipment (products) complies with the conditions of transportation, storage and operating instructions established by the Technical Specifications.
