|Applicants:||KOREA ELECTRIC POWER CORPORATION
|Title:||INSULATING DEVICE FOR CROSSARM OF ELECTRIC POLE AND MANUFACTURING METHOD FOR CROSSARM|
The present invention relates to an insulating device for a crossarm of an electric pole and a manufacturing method for an insulating crossarm, the insulating device comprising: a hollow pipe member; and an insulating tube which comes in close contact with at least outer circumferential surface of the pipe member so as to surround the pipe member, wherein the insulating tube is formed of an insulating shape memory resin and prevents a malfunction or an accident by eliminating a current-carrying path through an insulation, thereby supplying stable power and remarkably reducing investment costs for preventing malfunction.
