Detonating Cord

Detonating cord, also known as det cord or detonation cord, is a thin, flexible explosive material that is used to transmit a detonation wave from an initiator to a main explosive charge. It consists of a core made of high explosives, such as PETN (pentaerythritol tetranitrate) or RDX (cyclotrimethylene trinitramine), surrounded by a protective covering.

Detonating cord is commonly used in various industries, including mining, construction, and demolition. It is primarily used for controlled explosive operations, such as breaking rock or concrete, cutting metal, or initiating larger explosive charges.

The cord is typically initiated by a blasting cap or a detonator, which creates a shockwave that travels through the core of the cord at a high velocity. This shockwave then detonates the main explosive charge, causing it to explode.

Detonating cord is designed to be safe and reliable, with a predictable detonation velocity and high resistance to accidental initiation. It is often color-coded to indicate its explosive power and intended use.

It is important to note that the use of detonating cord should only be done by trained professionals who have the necessary knowledge and experience in handling explosives. Safety precautions and regulations must be followed to ensure the safe and effective use of detonating cord.
