An electrical wire includes a conductor and an insulating layer that covers the conductor and that is cross-linked. The insulating layer is a cross-linked product of a resin composition including (a) a base polymer containing polyolefin and a compatibilizer, (b) a photoradical generator of 0.5 parts by mass or more and 3 parts by mass or less relative to the 100 parts by mass of the base polymer, and (c) a reactive monomer of 1 part by mass or more and 5 parts by mass or less relative to the 100 parts by mass of the base polymer. A relative dielectric constant of the insulating layer is less than 2.5.

A roll rod for a vehicle includes: a front insulator connected to a powertrain; a rod bracket to mount the front insulator on a front end portion of the rod bracket; a case bracket disposed outside the rod bracket and fastened to a vehicle body; a stopping rubber formed at a rear end portion of the rod bracket and disposed in an inner space defined by the case bracket; and a rear insulator formed between the rod bracket and the case bracket, where the rear insulator is secured to an outer side surface of the rod bracket and an inner side surface of the case bracket. The roll rod enhances an insulation rate against vibration of a powertrain and improves durability while reducing manufacturing costs through the simple structure and application of an extrusion molding method.

An agricultural stake to support plants includes a fiberglass reinforced plastic (FRP) elongated member comprising a top end and a bottom end, and a textured exterior surface. The agricultural stake includes an elongated member comprising a thin walled tube having a top end and a bottom end, and the elongated member comprises fiberglass reinforced plastic and exhibits no flex memory. The elongated member has an exterior surface texture configured to provide purchase to a line attached to the elongated member, where the exterior surface texture is formed by an abrasive.

Disclosed are cable types, including a type THHN cable, the cable types having a reduced surface coefficient of friction, and the method of manufacture thereof, in which the central conductor core and insulating layer are surrounded by a material containing nylon or thermosetting resin. A silicone based pulling lubricant for said cable, or alternatively, erucamide or stearyl erucamide for small cable gauge wire, is incorporated, by alternate methods, with the resin material from which the outer sheath is extruded, and is effective to reduce the required pulling force between the formed cable and a conduit during installation.
