Leading Manufacturer, Supplier & Retailer of Copper Electric Detonators.

Copper Electric Detonators

We manufacture, export and supply Copper Electric Detonators. Designed with utmost precision, our Copper Electric Detonators comply with set industry standards. The Copper Electric Detonators are suitable for use in underground gassy mines and many other types of blasting. Our detonators offer a reliable means of controlled, simultaneous initiation of explosive charge. They are manufactured in No. 8 strength in copper shells. The copper shells are fitted with electrical fuse heads. PVC coated GI / copper leg wires are sleeved through a PVC plug and crimped to the detonator to ensure protection against moisture and water.

 

Shipping Information :

  • As per Imdg (International Maritine Dangerous Goods) Classifications
  • Class : 1, Division : 1.1, Group : B, Un No. : 0030, Page No. : 1257, Storage Catergory : II Type 'C'
  • As per PESo (petroleum and explsieve safety organization) Classifications ID No. : 716, Class : 6, Division : 3, Categrory : ZZ

 

Precautions :

  • Make sure that all connections are made with clean bare wire ends and if necessary freshly expose bare wire.

  • Make sure that the bare ends do not come in contact with any conductors such as power lines, pipes, rails or other paths of stray current.

  • Make sute that the shot-fiting cable is connected to the exploder just before fiting the shot and is immediately disconnected after the shot is fired. The exploder key must laways be in the possession of the blaster and not kept on the machine.

  • Ensure that the exploder used is of adequare capacity and the current is of the desired magnitude for full initiation fo the round.

  • Check the circuit for continuity before fiting the shots. This must be done using only "Blasters" ohm-meter.
