Vibration resistant cables containing a first conductor and a second conductor, each having a diameter d, are disclosed. The second conductor is twisted around the first conductor at a lay length between 3 feet and 6 feet to eliminate bagging of the vibration resistant cable during installation.

Provided are a high-temperature corrosion-resistant stranded conductor and a method for manufacturing the same, which relate to the field of high-temperature conductor technologies. The stranded conductor is formed by twisting a plurality of composite wire monofilaments, each including a highly conductive core wire made of copper or a copper alloy, and a high-temperature corrosion-resistant alloy cladding the core wire. The stranded conductor is capable of maintaining strength and transmitting a signal under a high-temperature atmospheric environment below 1000 C. for an extended period of time. By employing a plurality of twisted composite wire monofilaments with the above structure, the conductor achieves high strength retention, stable electrical conductivity, and superior oxidation/corrosion resistance when operating long-term under operating conditions of 600 C. to 1000 C. This solves the technical problem of conventional conductors failing in high-temperature environments.

Disclosed herein is a tree wire and a method of preparing the same. The tree wire disclosed herein has an improved ampacity compared to a conventional ACSR tree wire, as well as reduced sag compared to a conventional ACSR bare conductor and/or ACSR tree wire.
