Electrically insulative hollow-profile structural part with high-tension attaching elements and method of constructing same

摘要: An electrically nonconducting hollow-profile structural part having a protective cover, preferably made of polyester threads or fibers, with mechanically supporting glass-reinforced plastic core, especially for SF 6 insulating gas technology. The has an end that is conically shaped and connected to attaching element oppositely facing conical surface by means conically-constructed screw and/or cemented connections in such way the glass-fiber interfaces core exposed at are covered gastight cone superficies element. As result, insulation products separation which attack glass develop as result corona discharges cannot come into contact fibers.
