Description

Dyno Nobel produces a safe and accurate electric detonator with a strength rating of No.8.

The detonator is of the NPED-type, (Non Primary Explosive Detonator, US patent No.4.727.808), in which the primary explosive (lead azide) has been replaced with a secondary explosive.

This gives increased safety in both manufacturing and handling.

The electric detonator uses electrical energy to heat a bridge wire that ignites a burning mixture which in turns ignites a secondary explosive.

Application

For use in initiating blasts in underground and surface applications.

Features

  • The electric detonator provides increased water hammer resistance in blasting applications where saturated ground conditions exist.
  • The electric detonator is designed to function safely and reliably over a wide range of climatic and environmental conditions.
