It is high power detonator and initiated by an electric impulse. It can reliably initiate all explosives & detonating cords applicable for blasting work in well mining or in open pit, digging tunnels, road construction, building water conservancy project etc. Electric detonators are widely used to initiate blast sequence but are rarely now used inside the blast hole themselves except seismic prospecting. Electric energy is introduced into the detonator from out source via a primary circuit wire through detonator leads
