Epoxy glass laminate tube

 Epoxy glass laminate tube represent the layered material made by a method of continuous winding preliminary impregnated  epoxy binder  with subsequent it.

  Tube of glass fibre plastics are applied as  insulating a material to a complete set of the high-voltage equipment (oil and air switches) for work in transformer oil and on air in conditions of normal relative humidity of an environment and frequency of a current of 50 Hz at temperature from 60°С up to 90°С and also for work in conditions of the raised humidity of an environment (95±2) % and temperature from-60°С up to 155°С.

 As a constructional material epoxy glass laminate tubes are applied in a role casing  tubes to fastening oil and gas chinks and also in especially harmful manufactures as chemically proof tubes.

  Epoxy glass laminate  tubes can be applied with success as  heat-insulated a material in electric dryers heaters and other equipment .Connection of tubes among themselves can be made by means of the formed internal conic groove by means of pasted metal branch tubes and also can be made with external  underwinding on the ends for cutting an external groove. Epoxy glass laminate tubes  of mark «ТСЭФ» are issued d.10-100mm, marks «ЦСЭФ» from 105 up to 600mm.
