METHOD OF PRODUCING ELECTRIC INSULATOR AND ELECTRIC INSULATOR PRODUCED THEREBY Russian patent published in 2009 - IPC H01B17/14 

FIELD: electrical engineering.

SUBSTANCE: proposed method comprises producing bearing core by applying glass fiber strand on terminations, twisting aforesaid strands, curing of binder and applying coating. Bearing core is made of continuous glass fiber strand. Note that additional coils of strands are laid around terminations. Note also that aforesaid additional coils of one termination are connected with extending additional coils laid around the other termination with the help of fiber from shrinking material. Then bearing core and terminations compacted by shrinking-material band and impregnated by polymer binder. Lavsan, polyether can be used as aforesaid binder. Note that bearing core cross section area equals that of glass fiber layer laid around eye-type termination.

EFFECT: higher strength.
