Safety delay detonator
- Introduction
The KVA.8Đ Safety delay detonator consists of a special electric igniter fitted with a Safety delay detonator, on the electric wire with a label marking the number of the fuses. Wires are often used with 2 different colors to avoid confusing when making the connection. - Specifications

With a range of differential range, it is possible to design an efficient blast sequence when being used
- Packing and Storage
KVA.8Đ is classified into PE bags, air-pressed, sealed and stored in boxes. Each box is stored in a sealed PE bag, then stored in a wooden box. In each wooden box only one type of detonator is preserved with the same number of differentials.
