APPDD are available in 0-6 numbers with delay interval of 25milliseconds. The shells are made of copper material. The delay element is inserted above the primary charge and consolidated. The delay timing is achieved by the lead element on the primary charge. The two lead wires are passed through the PVC plug soldered with the fuse head and crimped.
Permitted delay detonators are used in gassy underground coal mines.
