Kunming City, China

We are offering electronic detonator.The digital electric detonator (edd) is a high-ranking intelligent product . Comparing with the common delay detonator, the edd has three advantages: 1. High accuracy: mean variation and its less than 0.2% in comparison with that 10% of the common delay detonator. 2. High reliability: the edd performance doesnt change under 70m water for 72hrs. The edd misfire ratio is one millionth comparing with that of common detonator between one ten thousandth and one hundreds of thousandth. 3. High safety: anti-static and anti-radio frequency.

We are offering detonating fuse.The common detonating cord is classified into cotton thread detonating cord and plastic detonating cord. The cotton thread detonating cord is made from explosive as its core, cotton thread and paper as its wrapper, and asphalt as its moisture-proof layer. The plastic detonating cord is made from explosive as its core, fiber as its wrapper and plastic as its moisture-proof layer. Its outer diameter is less than 6.0mm. It possesses the advantages of high detonating velocity, complete detonation and good water-resistant property. Its quality reaches the advanced level of the world. It is used in many key engineering projects of our country, such as three gorges dam. It is suitable for the demolitions in the open air. When connected into a cord net in the large demolition engineering and ignited by a detonator, it can detonate explosive bag groups.Velocity of detonation: not less than 6500ms. Detonating sensitivity: it can be completely detonated and when connected by the specified methods. Moisture-proof capacity: the cotton thread detonating cord can be completely detonated after 4 keeping hours in water of 1m deep at the temperature of 1025 when connected by the specified methods. The plastic detonating cord can be completely detonated after 5 keeping hours in water at the temperature of 1025 and at the pressure of 50kpa when connected by the specified methods. Detonating capacity: the detonating cord of 1.5m long can completely detonate a tnt block of 200g(press charge).Pulling-resistant capacity: it can be completely detonated after bearing a static pulling force of 500n.
