Description:
Type ZHUA features a galvanised steel core with a thick, smooth TPU cover which is halogen free and flame retardant in line with the smoke and fire requirements of EN 45545-2 and NFPA 130, ASTM E162, E662 and BSS 7239 standards. The conduit retains its flexibility at low and high temperatures and changing levels of humidity, is conduit is UL & CSA approved and has an integrated grounding copper wire (in sizes 1/2” to1.1/4”) to protect cables from electromagnetic interference. Type ZHUA is used in the metro-, train- and bus-building industry, in closed areas, airports, tunnels and (subway) stations, shipbuilding industry and navy.
