Claims

[Scope of utility model registration request]

(1) In a pleated cone-shaped insulating spacer to be attached to a conduit aerial cable, the distance between the pleats integrally formed on the outer surface and the inner circumferential surface of the metal sheath of the cable is as follows:
A pleated cone-shaped insulating spacer characterized in that the distance between the pleats integrally formed on the inner surface thereof and the inner peripheral surface of the metal sheath of the cable is greater than the distance between the pleats and the inner peripheral surface of the metal sheath of the cable.

(2) A cone-shaped insulating spacer according to claim (1) of the utility model registration, in which an outer face pleat and an inner face pleat are integrally formed on the inner and outer surfaces of a plurality of stages, respectively.
