INFLUENCE OF CURRENT-TIME CURVE OF PROTECTIVE INSTRUMENTS ON FIRE SAFETY OF CABLE PRODUCTS

Abstract

The paper provides results of experimental investigations on determination heating characteristics of ВВГ2x2.5, ВВГ2x4 and ВВГ2x6 cables and individual current-time curves of automatic switch-off series. Joint operation of automatic switch-offs and protected conductors are analyzed from the point of view of fire safety provision.
