Description and Application
SUPREMEDET’S LPD is a non-electric firing system used to detonate a shock-sensitive explosive in underground blasting operations with a long delay range. The Cobra clip mounted on the shock tube allows easy connection to the detonating fuse. If desired, it can be fired with SUPREMEDET’S STL non-electric capsules.
It is manufactured in various delay times to improve performance by providing enough time intervals for rock operations in blasting. It consists of 30 series to provide a delay range of 100-10,000 ms. This ensures that underground blasting models can be fully applied to the field.
It is not affected by wet environments, harsh weather conditions, radio waves, or static electricity, providing a safer use. Due to its spiral wrapping, it is easier and faster to distribute capsules into holes underground, and the delay numbers written in large fonts make it easier to distinguish capsules in the underground darkness.
