Description
Copper Connecting Wire - a.k.a. "Blasting Wire" - is manufactured using a solid, soft drawn annealed copper conductor. The most common is #20 Duplex - two wires covered with Polyvinyl-chloride (PVC) insulation. The PVC web between the two conductors allows for ease of separation without the use of tools. As an alternative to Duplex, the industry uses "Single" #20. Special requests are welcome.
Designed for use in mining, drilling and blasting industries.
