PROTECTIVE DEVICE FOR BLAST ISOLATION

摘要

A protective device for blast isolation has outer and inner coaxial cylindrical fiber-glass shells made of pyroelectric material with metal shell placed coaxially between those with direct contact and metal shells with coaxial placement with direct contact outside of outer fiber-glass shell. To increase reliability of two-layer fiberglass-plastic shell due to decrease of its maximal deformation the metal shells placed outside of the outer fiber-glass shell and inside of the inner fiberglass plastic shell are electrically connected one to another.
