CDET SIGMA Relay For Detonating Fuse (Cord Relay)
CDET Sigma relay is a non-electric surface initiator and provides delay between the holes and the rows in case of detonating cord initiated blasts. The delay is accomplished by cutting the detonating cord and attaching the cord relay to the cut ends. Cord relays are available in various delay intervals and are suitable for bi-directional use.
CDET Sigma can be used for providing various delay initiation patterns such as Row delay, Diagonal pattern, V-Pattern, etc. Where controlled blasting is required, CDET Sigma can be used in such a manner that only one hole blasts at a time thus keeping the maximum charge per delay
