HBL (RDP, JFB, BL) parallel constant power heating cable_Shandong Huaning Electric Heating Technology Co., Ltd

The parallel type constant-power electric heating series has a constant heat generation per unit length. The longer the electric current is used, the larger the total output power is. The maximum single-circuit length is longer. It is mainly used for pipes, instruments and tanks with high temperature. Insulation of body equipment; high temperature of maintenance and heating; can be used in explosive gas occasions in the first and second zones of the factory

The explosion-proof mark of the parallel constant power electric heating is: ExeIICT3 Gb

Parallel constant power heating cable is connected in parallel by multiple heating sections in the whole length. It can cut the length according to actual needs. It must be used together with the temperature controller when heating. It can accurately set the medium to maintain temperature and realize automatic control. The heat generation per unit length is constant, and the longer the electric heating belt used, the greater the total output power. In addition, the electric heating belt can be closely attached to the surface of the pipeline because of its softness. The outer metal shielding net can play the role of explosion-proof, anti-interference, heat transfer and heat dissipation, improve the overall strength of the electric heating belt, and can also be used as a safety grounding wire. Therefore, it is widely used for heat preservation, antifreeze and heating of pipes, valves, small storage tanks, pump bodies, etc.

The reinforced parallel type constant-power electric heating belt is coated with an anti-corrosion insulating layer on the outer layer of the ordinary electric heating belt. The rest of the structure is the same as that of the ordinary electric heating belt. In addition to the advantages of the ordinary electric heating belt, the reinforced electric heating belt has the advantages of High mechanical strength and strong anti-corrosion ability.
