What is a detonating cord?

The detonating cord is also called the detonating cord. It is a blasting equipment used to transmit detonation waves and directly induce explosives. It itself requires a detonator to detonate. See Figure 1.

1-core wire; 2-drug core; 3-internal layer; 4-mid layer;

5- moisture barrier layer; 6-paper strip layer; 7-outer layer; 8-coat layer

It RDX by the drug core, Tai made of high-power explosive drugs, look red, detonation velocity detonating cord is made 6500 ~ 7200m / s. The detonating cord has strong water resistance and is sealed at both ends. It can be completely exploded after being immersed in water for more than 24 hours.

The detonating cord can make a large number of explosives simultaneously detonate, and is widely used in the blasting of deep holes, medicine rooms and segmented charges. The disadvantage is that the cost is high.
