 Epoxy glass laminate  GOST-12652-74

 is made by thickness from 1,5 up to 50 mm. It is intended for work on air in conditions of normal relative humidity of an environment at a pressure from above 1000 V and frequency of a current of 50 Hz, and also for work on air in conditions of the raised humidity of an environment (93 +2) %, at temperature (40 +2) ºС at a pressure up to 1000 V and frequency of a current of 50 Hz.

High mechanical durability and electric stability allow to spend machining of a material and to use it for constructional details of an electric equipment.

Epoxy glass laminate  it is made by thickness from 0,5 up to 50 mm. Possesses the same properties, as , but has more homogeneous fine internal structure that allows to make of it fine details of an electric equipment.

It is long admissible working temperature from-65С up to +155С.
