Description: Hefei Anru RDP2-J4 High Temperature Constant Wattage Heating Cable - Overview
The working principle, structure, and application of the RDP2-J4 high temperature constant wattage heating cable are the same as the RDP2-J3 type, and it can be used in Zone 1 and Zone 2 gas mixtures of T3-T6 groups. The main differences are: higher high-temperature resistance grade: medium maintenance temperature ≤205℃, insulation material is high-temperature composite material and PFA fluoroplastic. The insulation layer material can withstand temperatures up to 260℃.

Application Scope:
The constant wattage parallel high-temperature heating cable consists of multiple heating sections connected in parallel along the entire length. It can be cut to the required length and must be used with a temperature controller during heating to precisely set the medium temperature and achieve automatic control. Its heat output per unit length is constant; the longer the heating cable used, the greater the total power output. Additionally, the heating cable is flexible and can closely adhere to the pipe surface. The outer metal braid serves to transfer heat and dissipate heat, enhances the overall strength of the heating cable, and can also be used as a safety ground wire. Therefore, it is widely used for insulation, freeze protection, and heating of pipelines, valves, small storage tanks, pump bodies, etc.
The reinforced constant wattage heating cable has an additional layer of anti-corrosion insulation over the outer layer of the standard heating cable, with the rest of the structure being the same as the standard type. Besides the advantages of the standard heating cable, the reinforced type also features high mechanical strength and strong anti-corrosion capabilities. The three-phase constant wattage heating cable, in addition to the characteristics of the single-phase type, also offers features such as a longer maximum usage length, excellent heating uniformity, and the ability to balance the power grid load.
