A grommet includes a hollow grommet main body, a protector placed in a hollow space of the grommet main body, and an outer member for fixing the grommet main body to an attachment surface. The grommet main body has a first grommet-main-body-side recess to engage with a protector-side projection of the protector, and a second grommet-main-body-side recess on an outer wall surface of the grommet main body to be adjacent to the first grommet-main-body-side recess. The outer member has an outer-member-side projection engaged with the second grommet-main-body-side recess. The protector-side projection and the outer-member-side projection are located to sandwich a portion of the grommet main body in a direction crossing to a pressing direction of the outer member when the protector is placed in the hollow space and the grommet main body being fixed to the attachment surface by the outer member.

Described is a plug-in bushing, a manufacturing method of same, and a high-voltage installation, more specifically, to a plug-in high-voltage bushing for connecting an external electrical conductor to a high-voltage installation filled with an insulating body, and to a high-voltage installation comprising the bushing. The plug-in bushing comprises: a conducting body; a resin insulating body surrounding the conducting body; an electric field-control electrode made of a semi-conducting synthetic resin material, coupled to an upper end of a lower support fitting; the lower support fitting connected to the outer circumference of a lower part of the resin insulating body; and injected insulating body produced by an insert injection including the outer circumference of the resin insulating body and electric field-control electrode, having formed thereon a plurality of fins; and a stress cone connected to a lower end of the resin insulating body.

A dielectric cover for an insulator and conductor in an electrical distribution includes an insulator cover portion for covering the insulator. A knob and ridge extend down from an inside ceiling of the insulator cover portion. An arm, for covering a portion of the conductor extending from the insulator, has a top keyhole, where the keyhole has a wide portion that fits over the knob in a first position and a narrow portion that restricts vertical movement of the arm in a locked position when the arm is withdrawn slightly. The arm also has a resilient tab that snaps over the ridge in the locked position, wherein the knob in combination with the keyhole restrict further withdrawing of the arm from the insulator cover portion in the locked position, and the tab contacting the ridge restricts further insertion of the arm into the insulator cover portion in the locked position.

A grommet includes a hollow grommet main body, a protector placed in a hollow space of the grommet main body, and an outer member for fixing the grommet main body to an attachment surface. The grommet main body has a first grommet-main-body-side recess to engage with a protector-side projection of the protector, and a second grommet-main-body-side recess on an outer wall surface of the grommet main body to be adjacent to the first grommet-main-body-side recess. The outer member has an outer-member-side projection engaged with the second grommet-main-body-side recess. The protector-side projection and the outer-member-side projection are located to sandwich a portion of the grommet main body in a direction crossing to a pressing direction of the outer member when the protector is placed in the hollow space and the grommet main body being fixed to the attachment surface by the outer member.

Mounting plates for elevating platforms, including a mounting apparatus with interior and exterior reinforcement components elongated vertically. The interior reinforcement piece includes an embedded bolt that extends from the interior reinforcement piece, through a wall of the platform, and through the exterior reinforcement component. The interior and exterior reinforcement components have a stepped construction to convert peel stress to shear stress.

A T-post insulator that includes means to attach in a plurality of locations around the post. The insulator portion of the device consists of an outer surface that wraps around the T-post about 270 degrees for optimal insulation of the wire. The wire is installed through means of a snap in action from the top center of the wire around a retaining post. The wire is insulated fully regardless if installed on a straight run or a corner installation where wrapping around the T-post is required.
