Selection of flame retardant cable note problems
- Dec 20, 2016 -

(1) due to the halogen-free flame retardant cable (including flame retardant cables low smoke and low halogen-free flame retardant cable) when burned emit corrosive of halogen acid gas, significantly hinder fire-fighting delayed the fire and the fire spread in public places should be designed with higher population densities use low smoke zero halogen flame retardant cable. In the operational areas of lower population density can choose either flame retardant cable.

(2) fire-retardant cables are divided into a, b, C3, class a fire retardant cable better than b, c class, price is the most expensive. Designers should be indicated when ordering inventory categories of flame retardant cable.

(3) visually indistinguishable from flame retardant cable category of a, b, c, only the manufacturer supplied guarantee, so in design should be very careful in choosing the cable manufacturer.

(4) low smoke zero halogen flame retardant cable compared with halogen-free flame retardant cable, low corrosion and the advantages of low-smoke, but significantly lower electric and mechanical properties, so when the cable, low smoke zero halogen flame retardant cable should have a greater than halogen-free flame retardant cable bending radius.

(5) when the cable is designed, non-flame retardant cable should not be tied with flame retardant cable laying should not be different categories of flame retardant flame retardant cable tie installation.
