Key Features
Detail of Blasting Wire
Electrical & Mechanical Properties
- The Duplex Blasting Wire configuration features a precision-twisted pair design, which provides superior EMI (electromagnetic interference) resistance and enhanced physical durability during deployment. Whether utilized as a primary Lead-in Wire for long-distance surface blasting or as a dedicated Connecting Wire for intricate circuit patterns, our product guarantees minimal signal loss.
- Designed for versatility, it is also highly compatible as a Detonator Wire (commonly known as Leg Wire in specific regional markets), offering a secure and stable link for both conventional and electronic digital detonators. With a focus on high tensile strength and low electrical resistance, our Blasting Wire is the trusted choice for ensuring operational safety in the most challenging environments.
