Behaviour in fire:
Flame retardant cable acc.to IEC60332-1
Application:
Insulated conductor(H05V-U/ H07V-U/R) is used for laying in electric-installation tubes, under and on plaster installation in dry rooms and in closed installation conduits. Direct laying in cable guides is not permitted. Also applied for internal wiring of distribution and switching boxes equipment, same as for protective laying for lighting of nominal voltage up to 1000 V alternating current, or up to 750 V direct current against earth.
Installation :
Permissible currentare given for conductor laid alone in insulating tube on a wall temperature at 30°C .
