INSULATED POLE BAND FOR ATTACHING TRUSSED BEAM

摘要

PURPOSE:To remove the danger of electric shock by attaching a trussed beam in a high-tension direct current section under a condition where earthing from the trussed beam to a pole is prevented. CONSTITUTION:An insulated attaching plate 3 is boltedly fixed to the outside faces of a pair of band bodies A embracedly fixed to the pole P at required intervals in a vertical direction. The end of the beam is bolted to the outside of the attaching plate 3 in a horizontal or oblique direction. Beam attaching bolt holes in directions being horizontal and oblique to the band body A are drilled on the attaching plate 3. The band body A and the nearest beam attaching bolt hole are mutually separated at least farther than the surface leaking distance of the attaching plate material.
