Ama Cord Relay

Characteristics :-ama cord relay is a non electric surface delay initiating device, it provides delay between the holes & the rows in detonating cord. The delay is provided by cutting the detonating cord & attaching the cord relay to the cutting ends. Specification :-cord relay consists of two delay devices housed in a white plastic component. Two holes are provided at either ends for threading the detonating cord.for identification delay nos. Are mentioned on the component-cord relay 17 ms cord relay 25 ms cord relay 50 ms cord relay 67 ms cord relay 100 msapplication :- cord relays can be used for providing various delay initiation pattern such as row delay, diagonal pattern, v pattern,etc. Where controlled blasting is required, cord relays can be used in such a manner that only one hole blasts at a time thus keeping maximum charge per delay. Advantages :-cord relay are non electric and thus are immune to extraneous electricity sources and radio frequency (rf) energies. Use of tie-lines in the surface hook up provides two or three detonation paths thus minimising risk of fire. Use of a combination of cord relays of different timings allow large blasts to be carried out with minimum ground vibration. Firing of one hole at a time is possible where required. packaging :-cord relays are packed in cartons of 50 nos. Each, such cartons are packed in wooden/cardboard cases. Cord relays are packed in standard quantity of 1000 pcs.
