Comparing with Common Seismographic Electric Detonator, this product has the function of radio-frequency resistance, so the safety of the product is improved. It is good at synchronized ignition and has a strange resistance to static electricity. The radio-frequency and static-electricity resistance of this product is better than that of the Common Seismographic Electric Detonator.

Technical Parameters

Shell material：cooper-clad nickel-plated steel, copper

The core material of blasting cord：copper

The length of blasting cord：2m (It can be determined as required by customer.)

Series detonating current：When 20 electric detonators are connected in series with 3.5A constant DC current, all 20 detonators shall explode.

Water resistance：Immerse the products in water at the depth of 30m for 72 hours, the initiating performance shall not change.

Radio-frequency resistance (For radio-frequency resistance type)：For 50MHz-200MHz frequency, the radio frequency will be attenuated by 20db.
