H05V-U / H07V-U
H05V-U: Single core non-sheathed cable with solid conductor for internal wiring, 300/500V, 70º C
H07V-U: Single core non-sheathed cable with rigid conductor for general purpose, 450/750V, 70º C
Application
H05V-U is suitable for the installation to the inside of apparatus as well as for the protective laying to the lightings, in dry rooms, in production facilities, switch and distributor boards, in tubes,under and surface mounting of plasters.
H07V-U is suitable for laying tubes, under and surface mounting of plasters and also in closed installation conduits; it is permitted for the inner wiring of equipment, distributor and switchboards and also for protective laying to the lightings with a nominal voltage up to 1000 V alternating current or up to 750 V direct current against ground.
