INQUIRY

220v RDP2-J3 parallel constant power electric heating cable is mainly used for antifreeze and heat preservation of various pipes and meters. The higher maintenance temperature can reach 150℃. It can be used in explosive gas occasions in the first and second areas of the factory.

Example: RDP2-J3-30: Indicates that the insulating material is F46 fluoroplastic, the rated power is 30W/m, and the working voltage is 220V single-phase ordinary constant power electric heating cable.
220v RDP2-J3 parallel constant power electric heating cable structure and working principle
The power bus bar is two parallel insulated soft copper wires. Nickel-chromium heating wire is wound on the inner insulation, and the heating wire is connected to the bus core wire at a certain distance (ie "heating section length") to form a continuous parallel resistance. . After the bus core wire is energized, the associated resistances generate heat, thus forming a continuous heating band, and can be spliced at will according to the use of the heating section length.
220v RDP2-J3 parallel constant power electric heating cable specifications and main parameters
Higher maintenance temperature: refers to the process temperature that the medium in the pipeline needs to maintain, and generally should not exceed the value specified in this table.

Normal insulation resistance: ≥20MΩ/100 meters
Dielectric strength: 2000VAC/50HZ/1min
Long-term high temperature resistance: 205℃
Explosion-proof mark: ExeⅡT4
Protection level: IP56 IP65
The unit of single-phase parallel constant power electric heating cable has a constant heat output. The longer the electric heating cable used, the greater the total output power. The electric heating cable can be cut to the actual length required on site, but the shorter is not less. At 1 hot node. Due to the flexibility of the electric tracing cable, it can be conveniently laid close to the surface of the heating pipe. The outer layer of the electric tracing cable has a copper wire shielding braid, which not only has the function of heat transfer and heat dissipation, but also can improve the overall tensile strength of the electric tracing cable. At the same time, it can also be used as a safety grounding wire.
