RDP3-J3-40 means：insulation material F46 fluoroplastic, 40W/m three-phase general type constant power heating tape
RDP3Q-J3-40 means: insualtion material F46 fluoroplastic, 40W/m three-phase reinforced type constant power heating tape
Structure and working principal
Power buss wire consists of 3 parallel insulation copper wires with heating wires winded to
inner insulation layer, heating wires be connected to buss wires every certain distance which
forms continous parallel resistances, After power
on buss wires, all parallel resisatances will heat and form a continous heating tape
