A reinforced cable tie generally includes an elongate strap, a head attached to a first end of the strap and a continuous fiber reinforcement disposed in and extending substantially continuously along a path defining at least one of the strap and the head. The head has one or more apertures formed therein and a locking device disposed in the aperture of the head. The locking device is configured to permit a second end of the strap opposite the head to be inserted through the head aperture in a first direction and is further configured to prevent movement of the second end of the strap from the head aperture in a second direction opposite the first direction.

A method for injection molding of thermoplastic pole parts utilizes a mold to fix at least one vacuum interrupter and contact terminals during a molding process. At least one injection opening or gate for injection of thermoplastic material is formed into the mold. The mold is applied with multiple injection openings at least along its long axis, for injection of hot thermoplastic material, and the injection openings or gates can be steered in such a way that they inject thermoplastic material simultaneously or with a defined time dependent injection pattern. This process alleviates the issue of a pressure gradient along the long axis of the molded pole part, shortens process times, and achieves a homogenous dissipation of material during the molding process.
