UL1007 Topcoat Hook Up Wire is a 300V lead wire used across a variety of engineering and electronics industries. The topcoat tinning means that the bare copper strands in this wire are twisted together and given an overall coating of tin, which provides good electrical connectivity and easy soldering. Additionally, the PVC jacket protects the wire against abrasion, chemicals, oils, and solvents. By conforming to UL specifications, the hook up wire provides excellent uniformity for processing, stripping, and terminating.
